Nick Chen addresses rumors that the American director is remaking Jang Joon-hwan’s 2003 sci-fi comedy about aliens conspiracy theories

When Titanic was a blockbuster freak in 1997, he spawned a star in Leonardo DiCaprio — and also a rumored freak. In response to Titanic, an anti-Leonardo DiCaprio website claimed that the actor is actually an alien trying to take over Earth by having sex with the planet’s female population. As of 2022, the blog post no longer exists, nor does the original conspiracy theory (we now know that DiCaprio wouldn’t sleep with women over 25). It did, however, inspire South Korean filmmaker Jang Joon-hwan to write and direct Save the green planet!a 2003 comedy that could well become a 2024 comedy, should Ari AsterRemake plans are coming to fruition.

In 2020, Aster and Lars Knudsen have announced that their production company, Square Peg, is collaborating with CJ Entertainment, the studio behind Parasiteto redo Save the green planet! for modern audiences. According to the press release, Jang will direct from a script written by Succession writer Will Tracy, and, by Aster, the updated version in the United States “will reflect the messiness of today’s world”. Could it feature DiCaprio as an alleged alien? Maybe Cousin Greg? Two years later, we are still waiting for an update.

In the meantime, Jang’s original Save the green planet! is a riot genre mashup worth your time. Accompanied by a punk cover of “Over the Rainbow,” the opening credits establish what’s to come: a raucous show of cinematic tropes. Here, DiCaprio’s figure is Kang Man-shik (Yun-shik Baek), a wealthy and suited CEO who is captured by Lee Byeong-gu (Shin Ha-gyun), an incel-ish beekeeper who is convinced that Kang is a alien from the planet Andromeda. If Lee is correct, Kang’s Andromedan companions plan to exterminate the human race in order to save planet Earth from the humans themselves. Hence the underlying gag: even in Lee’s logic, humanity is the bad guy fighting global warming.

What distinguishes Save the green planet! of, say, other goofy bullshit theorizing that wealthy businessmen are secret Martians is Jang’s sparse approach to tone. One scene might be a painfully heartfelt, dialogue-driven reveal of Lee’s tragic background, the next might be an animation, 2001– referencing a flashback featuring dinosaurs or a musical interlude involving Lee’s circus-playing girlfriend. Also intercut is a shocking subplot about detectives suspecting Lee of the kidnapping. As a swarm of bees commits a giallo-style cinematic murder, you half wonder if Jang is treating the film as a show for his versatility.

Even then, nothing can prepare viewers for the detour through torture porn. Imprisoned by Lee, Kang is tied up and experimented on, with his three weak spots supposedly being his feet, his eyes, and between his legs. With Kang shaved, electrocuted, and repeatedly questioned about his UFO philosophy (which he denies through tears of pain), it’s obvious we’ve witnessed this dynamic before, just in reverse. In an interview with The voice of the villageJang cited two basic ideas: “this anti-DiCaprio website” and telling Misery from the kidnapper’s point of view.

Without surprise, Save the green planet! was a box office flop, both in South Korea and overseas. Sympathize with an anti-hero? In 2003? On this planet? But any fan of AsterMovies should be open-minded. Take Hereditary, a global hit starring Toni Collette as a mother who says to her son, “All I get is that fucking face on your face.” Or Midsommara relationship drama that has audiences cheering when Florence Pugh’s Dani chooses to watch her boyfriend burn alive.

In fact, in a 2019 IndieWire characteristic, Aster specifically named Save the green planet! as the main source of inspiration for Midsommarthe breathtaking conclusion. He explained, “There are so many South Korean movies that have come out in the last 20 years…I love how they juggle the tones.”

As Asterthe two released feature films (and, allegedly, his upcoming Boulevard of disappointment.), Save the green planet! is a bloody, messed up, utter genre extravaganza with family trauma at its heart. In homemade protective gear that’s a slightly more advanced version of wrapping himself in foil, Lee looks comically absurd – more SNL than Spielberg. But Shin imbues so much seriousness into the ridiculous dialogue that you accept the chaos. And, of course, Lee’s gory story is shrouded in so much nonsense that it doesn’t quite resonate like Dani losing her parents and sister before. Midsommar’s opening credits, but that explains a method to the film’s madness.

Kang owns Yuje Chemicals and Lee’s mother, an employee of the pharmaceutical company, was poisoned and has been in a coma for years. Additionally, Lee was beaten by teachers, his father was abusive, and during a time in prison he was assaulted further. To ease the pain, Lee turned to conspiracy theories. At the time, there was no Joe Rogan podcast, so he opted for the next best thing: choosing to believe that the man responsible for his mother’s impending death is a UFO.

Maybe, then, Save the green planet! really needs a modern update. In 2003, writing online that DiCaprio is a dangerously sexy alien was a funny blunder; today could be QAnon’s last tweet. And, if DiCaprio is involved in the new version, the actor could come full circle on his Titanic days, satirizing the alien nature of fame and the self-righteous element of its Don’t look up press tour. Besides, a remake may seem illogical, but so does the original film. As Aster noted when presenting Jang’s science fiction at a 2019 repertoire showing, “This is a movie that shouldn’t work but it really does do it beautifully.”

When Congress directs the White House Office of Science and Technology (OSTP) to coordinate with other relevant federal agencies to seek a five-year scientific assessment of solar and other rapid climate interventions, it does not is all too evident that the highest levels of government have gotten the internal memo that the climate is in trouble. Even so, they’re still late to the party.

Scientists have been warning of the consequences of excessive CO2 levels and urging Congress and the White House to act for decades.

Now that the broken climate system has been recognized as a serious threat, as a general rule, if something is broken, it can be fixed. There is no other plausible outcome. Otherwise, it wouldn’t have been possible to build it in the first place, or seen in another way, if it can be built, it can be fixed.

But is it possible to fix a broken climate system? That is to say, the system on which we all depend for the maintenance of life. But, we didn’t build it. Yet we broke it. Thus, it does not conform to the axiom: “If it can be built, it can be fixed”. Ergo, this may be a bigger challenge than the current scramble to find solutions to build fast enough to turn down the heat.

In this sense, there are a wealth of readily available facts to prove that the climate system is truly broken (a long list is available upon request). Of most concern is the degradation of various ecosystems, but not all, which is occurring much sooner at such a low +1.2°C global average temperature change above the pre-industrial period than anyone thought possible. At just +1.2°C, the planet’s life support, which is our only life support, is at an undetermined level of risk, and no one knows how soon the major blackout will occur, estimates range. from (a) in this decade to (b) beyond this century. All of this raises the awkward consideration that scientists’ models have been off-target by a country mile for the past few decades. They are almost always too conservative and overwhelmed by real climate change. They’re late for the holidays.

Nevertheless, there are many climatologists, engineers, physicists who say: “Yes, this can be solved via the engineering of the climate system”. In fact, they are currently sending recommendations to the White House Office of Science and Technology. It’s really urgent.

While it is interesting to note that in fact human influence has already modified or geo-modified the climate system by altering the composition or chemistry of the atmosphere with massive emissions of greenhouse gases, the CO2 for example.

Engineering, or is it geoengineering, the climate system is a yes/no problem among experts and non-experts, maybe no, and it’s controversial enough to inspire loud cries and physical threats . It’s wild out there in the provocative world of “pro or anti” geoengineering.

Depending on who you meet at the airport bar and grill and strike up a conversation about geoengineering, it’s either feared, ridiculed, praised, or punched in the face, no soft opinions in between. There are websites dedicated to the study of geoengineering. Conspiracy theories abound. And, there are serious research programs going on at major universities around the world like MIT and Harvard and Stanford and Cambridge.

“Relevant scientific research on direct climate cooling methods and technologies currently being conducted include sea cloud thinning, stratospheric aerosol injection, sea ice freezing, thermal energy conversion oceans, oceanic and glacial microspheres, terrestrial and atmospheric mirrors, thinning cirrus clouds, iron salt aerosols, and white reflective roofs and streets (Source: Suzanne Reed, Healthy Planet Action Coalition, Compilation of Comments Submitted to the White House Office of Science and Technology Policy Regarding the United States Climate Response Study by HPAC and Affiliated Organizations and IndividualsSeptember 9, 2022)

In the Consolidated Appropriations Act of 2022, the White House Office of Science and Technology (OSTP), in coordination with other relevant federal agencies, was instructed by Congress to seek a scientific assessment of five years of solar and other rapid climate interventions in the context of long-term climate risks and hazards. In other words, key people at the highest levels have received the disturbing message that climate change is an extremely serious matter and a threat to stable ways of life.

The assessment will address: “(1) the objectives of scientific research (2) the capabilities needed to model, analyze, observe and monitor atmospheric composition (3) climate impacts and the planet’s radiation balance (4) what that is necessary for the coordination of federal research and investments needed to provide assessment at the point of managing near-term climate risk as well as climate response research,” Ibid.

Evaluation, as noted above, is the long version of saying: We have a serious problem that requires immediate attention.

A tagged fixit program The climate triad is brought to you by the Healthy Planet Action Coalition (HPAC), which is a diverse international coalition of scientists, engineers, technologists, and public policy buffs. HPAC recommends a coordinated program involving (1) Direct Climate Cooling, DCC (2) Reduction of Greenhouse Gas Emissions (3) Removal of Greenhouse Gases, GHGR. All three should be treated as equal priorities in an effort to keep global average temperatures below pre-industrial 1.5°C (when did it start?).

The tone of the fixit message is that of the urgency to deploy direct climate cooling “now necessary to reduce current and near-term damage and risk to humans and other species from current and near-term future levels of the global warming”, Ibid.

As such, and with even greater urgency, the coalition is asking the White House to work to shorten the proposed five-year research and implementation plan by accelerating it to one to two years. Implicit in this urgent request, coalition members evidently believe that climate change is so dangerously proactive that mitigation efforts must begin as soon as possible, which reinforces the HPAC’s request to start by compressing the timeline to 1-2 years from the five-year plan as stated by Congress.

For a list of HPAC proposals or to join their efforts, go to: https://www.collaborationconnection.org/

For example, the coalition submitted a menu of 15 proposed climate cooling approaches, such as: (a) thinning of cirrus clouds (b) ice shields to thicken polar ice (c) injection of stratospheric aerosols . And, of the utmost importance, polar refreezing is considered a top priority in support of national and international security objectives, protection of biodiversity, reduction of extreme weather events and raising the level of the sea.

At the top of the HPAC list: “Arctic amplification (with up to four times the temperature rise of the equator) and the role of Arctic sea ice in regulating climate by the jet stream and ocean currents make the Arctic Circle the most serious planetary problem. warming risk and cooling priority”, Ibid.

This sense of urgency about climate change and the big push by Congress for the White House to take a leadership role in a massive attempt to fix the climate system is a positive testament to the influence of a Democratic-led Congress. . There is no other way to see things. What is the GOP position?

Yet there are two sides to this rushed and hopeful rescue plan. One side is almost 100% certain that human engineering of the climate system will be positive, and thus the only way out of a sticky climate change/global warming problematic quagmire.

The other side believes that an artificially (human) engineered climate system is destined to trigger unintended negative consequences that could spiral out of control.

And, to all appearances, some aspects of the climate system are already out of control. Just ask anyone in Pakistan to tell you about the Himalayan range, where global warming has hit alpine glaciers with the bursting of glacial lakes or ask the barge companies on European rivers or the hundreds of cities living off water by truck in France and Italy, or the nearly “dead” Lake Mead. pool,” and the list could go on and on. All of this is happening at unprecedented levels never seen before, signs of a disruptive or broken climate system. Nothing is normal anymore.

Naturally, it is the intended consequences (mentioned above) that create the urgency and the need for massive planetary experimentation. But, so far, almost all proposals are desktop models. The real world is waiting for the tests to hopefully lead to real results that work as intended.

If it works, it will be something to behold, kind of like a miracle.

Stay tuned!

A newly discovered half-water, half-rock planet is straight out of science fiction https://sinia-planeta.com/a-newly-discovered-half-water-half-rock-planet-is-straight-out-of-science-fiction/ Tue, 13 Sep 2022 21:31:00 +0000 https://sinia-planeta.com/a-newly-discovered-half-water-half-rock-planet-is-straight-out-of-science-fiction/ Since the 1990s, scientists have cataloged thousands of planets outside our solar system, called exoplanets.

Since the 1990s, scientists have cataloged thousands of planets outside our solar system, called exoplanets. Some of them are massive and gaseous, while others are tiny and rocky like our homeworld. But recent analysis suggests some of these exoplanets could be denser and hold more water than previously thought, with big implications for extraterrestrial life.

There are four main types of exoplanets: Neptunian, gas giant, super-Earth and terrestrial. It is not easy to spot these planets directly, let alone understand what they are made of. One of the most proven methods of hunting exoplanets is called transit photometry, which basically involves pointing a telescope at a star and measuring the light as a planet passes by. A drop in brightness indicates that a planet is there.

But two astronomers, Rafael Luque of the University of Chicago and Enric Pallé of the Universidad de La Laguna in Spain, wanted to find the density of certain exoplanets. When they took a closer look at some of this transit data, they discovered something was wrong.

By analyzing data from a directory of 34 planets, Luque and Pallé discovered that some planets contained more water than previously thought. The new analysis would make these planets about 50% water and 50% rock, which would constitute a new class of exoplanets. In contrast, the Earth is almost entirely made of rock and contains far less than 1% water overall, even though its surface is covered with a large amount of water. Scientists believe that water is essential for life as we know it.

“It was a surprise to see evidence of so many water worlds orbiting the most common type of star in the galaxy,” Luque, the paper’s lead author, said in a statement. “This has huge implications for the search for habitable planets.” Their results were published in the journal Science.

The idea of ​​such a heavily waterlogged world was once the stuff of science fiction. A 1998 episode of “Star Trek: Voyager” featured the explorers visiting a planet composed entirely of water, resembling a spherical sea.

To make the discovery, Luque and Pallé looked at small planets transiting around red dwarf M stars — an extremely common type of star in the visible universe, but much smaller and cooler than our Sun. It is believed that when the planets around M dwarfs first form, they start out as spinning disks of dust and gas. Slowly they take on the marble shape we all know, but first form shields of hydrogen and helium called envelopes.

The husks slowly decay over time, eventually drifting through space. When estimating the mass and orbit of exoplanets, astronomers must take these envelopes into account. But when Luque and Pallé recalculated some of these measurements, they discovered that these envelopes probably don’t exist for some of these planets. Instead, they’re probably part rock and part water.

However, these planets probably do not have oceans. They are too close to their stars, which means any surface water would immediately evaporate and transition to a supercritical gas phase – essentially, a super hot fluid in which the distinct liquid and gas phases do not exist. This would expand their radius as they swing around their sun.

“But we don’t see that in the samples,” Luque explained. “This suggests that the water is not in the form of a surface ocean.”

Instead, it is likely that water is embedded in the rock of these planets in equal proportions, possibly forming pockets below the surface. This may sound familiar: Europa, a moon of Jupiter, is believed to contain liquid water underground and, therefore, may support life. NASA hopes to send a probe to Europa in 2024 to search for signs of extraterrestrial life.

There are perhaps billions of planets in the universe. According to the Encyclopedia of Extrasolar Planets, 5172 exoplanets have been discovered so far, occupying 3816 planetary systems. Due to their relatively smaller size and the fact that, unlike stars, they generally do not generate their own light, planets are much harder to spot with telescopes than stars – which are estimated to be 200 miles away. billion billion, or 200 sextillion.

Compared to the large number of stars observed, 5172 exoplanets is a much smaller sample. But it continues to grow and new discoveries on these other worlds are regularly announced. Diamond rain can be quite common on some exoplanets, for example, while two Earth-like exoplanets were recently discovered 105 light-years away.

Do any of these exoplanets harbor extraterrestrial life? So far, scientists have no idea. But tools like the James Webb Space Telescope will make it easier to discover what exoplanets are really made of and whether they harbor at least the right materials to make life possible. So far, there are plenty of good candidates, but this new study could greatly add to that growing list.

Temperature profiles and mixing ratios of H2O and CO2 from the SPECULOOS-2c atmosphere models: (top) two Hot Earths (Hot Earth 1 & 2), (middle) two humid greenhouses (Runaway 1 & 2) with a Low and high CO2, and a fully runaway (Runaway 3) greenhouse model (bottom) of CO2-dominated atmospheres (CO2-atm) and a modern Venus VIRA atmosphere (modern Venus).

astro-ph.EP

Venus and Earth offer a startlingly different view of the evolution of a rocky planet, raising the question of why these two rocky worlds evolved so differently.

The recently discovered transiting rocky planet LP 890-9c (TOI-4306c, SPECULOOS-2c) is the key to this question. SPECULOOS-2c (1.367 + 0.055 -0.039 R_Earth) circles a nearby M6V star of relatively low activity (32 pc) in 8.46 days. SPECULOOS-2c receives 0.906 +/- 0.026 of the flux from modern Earth, putting it very close to the inner edge of the conservative habitable zone, where models differ sharply in their prediction of how long Earth-like planets can conserve their water.

Our atmosphere models show that the transmission spectra of observable species can tell the difference between a hot and humid Young Earth, a scorching rocky planet caught in a runaway greenhouse on the brink of total water loss, and an analogue of Venus. Distinguishing these scenarios from the planet’s spectra will provide key new insights into when a hot terrestrial planet loses its water and becomes a Venus.

SPECULOOS-2c is a prime target for observations with JWST. Observing it will also provide key information for predicting Earth’s long-term future.

Two super-Earths discovered 100 light-years away – and one is potentially habitable https://sinia-planeta.com/two-super-earths-discovered-100-light-years-away-and-one-is-potentially-habitable/ Wed, 07 Sep 2022 11:00:44 +0000 https://sinia-planeta.com/two-super-earths-discovered-100-light-years-away-and-one-is-potentially-habitable/

If NASA’s collection of more than 5,000 exoplanets were a zoo, you’d find Jupiter lookalikes on every corner and worlds with a waterless rain covering the entrance. You’d stumble upon hellish landscapes behind arid paths and perhaps a pop-up exhibit of an ocean planet born from Poseidon’s daydreams.

But if this zoo really imitated life, you’d probably see most scientists hanging out in a room with all the “normal sounding” planets. Places that look a bit like Earth, the most plausible places to sustain life. (Well, life as we know it, at least).

NASA’s Exoplanets Division, for example, calls Trappist-1 the most studied planetary system besides our own. It’s very Earth-y, containing seven rocky worlds with the potential to hold water.

“It is important to detect as many temperate terrestrial worlds as possible to study the diversity of exoplanet climates, and ultimately to be able to measure the frequency of emergence of biology in the cosmos,” said Amary Triaud, professor of exoplanetology at the university. of Birmingham, said in a statement.

Thus, on Wednesday, Triaud, accompanied by a crew of international astronomers, reported the exciting detection of two other
temperate and earthly muses to explore. About 100 light-years from Earth, this planetary pair orbits a star called Speculoos-2 — yes, like the cookie — named after the telescopes that determined their existence: the Search for Habitable Planets Eclipsing Ultra-cool project. stars. Details of the researchers’ findings will be published in an upcoming edition of the journal Astronomy & Astrophysics.

“The goal of Speculoos is to search for potentially habitable terrestrial planets transiting some of the smallest and coolest stars in the solar neighborhood, such as the Trappist-1 planetary system, which we discovered in 2016,” said Michaël Gillon. , from the University of Liège. and principal investigator of the Speculoos project, said in a statement. “Such planets are particularly well suited to detailed studies of their atmospheres and to the search for possible chemical traces of life with large observatories, such as the James Webb Space Telescope.”

Profiles of exoplanets

According to the researchers of the new study, one of the two worlds had already been identified by NASA’s Transiting Exoplanet Survey Satellite, but it was not until Speculoos stepped in that scientists were 100% certain that this planet was indeed a planet.

Then, after some analysis, the team concluded that the world, named LP 890-9b, is about 30% larger than Earth and completes an orbit around its common star every 2.7 days.

“Follow-up with ground-based telescopes is often necessary to confirm the planetary nature of detected candidates and refine measurements of their sizes and orbital properties,” Laetitia Delrez, postdoctoral researcher at the University of Liège and lead author of the paper, said in a statement.

Two white domes are under the sky, on what looks like rocky desert ground.  Here are some of the Speculoos telescopes.

The other planet, named LP 890-9c, was a bit more mysterious. He was previously unknown. But after some testing and sorting through the data, the team estimated that the world was around 40% larger than Earth and had an orbital period of around 8.5 days, a bit longer than its sibling.

This orbital period is pretty exciting, though, because the researchers say it means the exoplanet is physically located in its star’s “habitable zone.” The habitable zone simply refers to the region around a star that is neither too hot nor too cold to sustain liquid water for billions of years. Sometimes the range is aptly called the Goldilocks area. “It gives us a license to observe further and find out if the planet has an atmosphere, and if so, to study its contents and assess its habitability,” Triaud said.

Hopefully, if NASA’s Webb Telescope can decode some of this information, it will unveil an answer to the biggest question of all: Are we totally alone in the cosmos?

But don’t get too carried away. It’s probably far from here. You can find me at the Exoplanet Zoo there, probably looking at the non-spherical planets exhibit. This one is shaped like a rugby ball. Isn’t that the weirdest?

From smart homes and consumer devices to connected workplaces and complex industrial monitoring, the Internet of Things (IoT) has endless potential. By nature, the IoT connects the physical world to the digital world, providing visibility into processes that was not available before.

As connectivity options become more robust, the IoT world is no longer limited by geographic constraints. Satellite networks can now connect to existing terrestrial networks, expanding the world of IoT across land, sea and sky. Long range networks have vastly expanded tracking options. When combined with a system of connected sensors, this wide area network potential has created new opportunities for IoT technology to make our planet smarter.

By the sea

A healthy ocean is essential for the future of our planet, both as home to essential biomes and as food for the growing world population. In fact, aquaculture continues to be one of the fastest growing food production sectors according to the Food and Agriculture Organization of the United Nations (FAO). The FAO predicts that aquaculture production will increase by 15 percent by 2030.

As the demand for aquaculture grows, the health of our oceans and the marine life they support becomes even more important. A climate-smart pilot program in New South Wales, Australia uses sensors from ICT International to monitor water quality in oyster farming systems. Water quality varies due to rainfall, sewage and flooding, which impacts oyster health. Water sensors monitor quality by detecting salinity and temperature, and can communicate critical information, including the ideal harvest window and alert oyster farmers when deteriorating conditions require estuary closure.

By plane

Air quality is of the utmost importance, both indoors and outdoors. The COVID-19 pandemic has highlighted the importance of indoor air quality. Whether at home, in the workplace, or in healthcare and other facilities, people want to make sure the air they breathe is clean.

A school board in Montreal, Canada recently deployed an IoT solution from Milesight in over 47,000 classrooms across the province of Quebec. The beauty of this deployment is in its simplicity: deploying long-range sensors in each classroom required an installation time of only about five minutes per room. The sensors transmit data such as CO2 level, humidity and temperature to the walkways at five-minute intervals during school hours. This information is used to implement corrective actions when key thresholds are reached, ensuring that fresh air is pumped into the classroom. The system also facilitates the analysis of historical data, allowing facility managers to determine HVAC repair needs.

Air quality monitoring is particularly important in healthcare facilities. A university hospital in Paris recently piloted an air quality monitoring and contract tracing solution to control the spread of viruses. To simulate contact tracing, the pilot fitted staff and students with Bluetooth-enabled badges to wear in the hospital. Sensors measured CO2 levels against occupancy rates, as well as ventilation changes or malfunctions. Technology offers the possibility of evaluating these factors to better predict – and, in the future, limit – the spread of viruses.

Outdoor air quality is a vital indicator of the health of our planet. Wildfires can have a devastating impact on communities due to the damage caused by the burns as well as the overall impact on the environment. In an average year, wildfires add 13 billion metric tons of carbon to the atmosphere. IoT technology can be used to detect wildfires earlier, alerting authorities before fires get out of control. For example, a solar-powered detection system from Dryad can detect abnormal patterns of smoke, temperature, humidity and atmospheric pressure, alerting firefighters within 30 to 60 minutes of the fire starting.

By land

According to the United Nations, the world’s population of 7.6 billion is expected to reach 8.6 billion by 2030 and 9.8 billion by 2050. In the face of a growing population, farmers are tasked with finding sustainable and efficient ways to ensure sufficient food production. From measuring crop growing conditions to tracking livestock health, the IoT enables farmers to identify efficiencies that maximize yield and encourage sustainable farming practices.

Australia-based Smart Paddock uses IoT-connected ear tags to monitor livestock and deliver real-time information to herders. Ear tags combine the long-distance, low-power capabilities of a network using LoRaWAN with a Global Positioning System (GPS) to track livestock location and behavior data, ensuring herd safety and health.

IoT sensors can also measure water usage and crop health to ensure plants are growing efficiently while minimizing water usage. Because the soil is not homogeneous, moisture levels vary, which means different areas of a field may need more water than others. Sensoterra’s sensors are equipped with soil probes, providing farmers with real-time data on soil moisture.

A more sustainable planet

The conditions of the ocean, sky and land are all essential to the overall quality of the environment and, therefore, to the quality of human life. Thanks to IoT innovations, detecting and responding quickly to environmental changes allows us to maintain the health of our planet.

The James Webb Space Telescope has detected carbon dioxide in the atmosphere of a distant planet surrounding a Sun-like star for the first time.

Why is it important: The JWST is designed to study and help scientists understand the compositions of exoplanet atmospheres in hopes of ultimately determining exactly what might make a world habitable.

  • Although this detection was made in the atmosphere of a gas giant that is unlikely to support life, it could help scientists understand what a carbon dioxide signal might look like for a potentially habitable world.

What is happening: The planet called WASP-39b – which has almost the same mass as Saturn but is larger in diameter than Jupiter – is located about 700 light-years away.

  • The JWST caught a glimpse of the planet as it passed in front of its star, backlighting its bloated atmosphere and allowing the telescope to analyze what it was made of.
  • During a transit like this, the light from the star is partially obscured by the planet and the starlight is filtered through the atmosphere, allowing scientists to obtain a spectrum of colors representing various molecules. that make up the atmosphere.
  • “The detection of such a clear signal of carbon dioxide on WASP-39b bodes well for detecting atmospheres on smaller, Earth-sized planets,” said Natalie Batalha of the University of California at Santa Cruz, who led the team behind the discovery. statement.

More: “Carbon dioxide molecules are sensitive tracers of the history of planet formation,” said team member Mike Line from Arizona State University.

  • “By measuring this characteristic of carbon dioxide, we can determine the amount of solid matter versus the amount of gaseous matter that was used to form this gas giant planet,” Line added.
  • “Over the next decade, JWST will make this measurement for a variety of planets, providing insight into the details of planet formation and the uniqueness of our own solar system.”

The James Webb Space Telescope has captured a spectacular image of a distant exoplanet, ushering in a new era of discoveries about distant worlds.

NasaThe James Webb Space Telescope has made history again, this time photographing a planet beyond our solar system. While astronomers have identified more than 5,000 exoplanets, most have been confirmed by methods other than direct photography.

The James Webb Space Telescope (JWST) has been making headlines since releasing its first batch of images this summer. The initial images from Webb include the Director’s Discretionary Early Release Science (DD-ERS), which is a program designed to provide astronomers around the world with immediate access to Webb’s data. The program gives the entire scientific community ample time to plan follow-up observations and contribute to groundbreaking discoveries. With an expected lifetime cost of more than $10 billion, the telescope has proven its worth by investigating distant solar systems, confirming the presence of carbon dioxide on distant planets, and teaching astronomers ever more about planets. close to space like Jupiter, among other discoveries.

This last image is of HIP 65426 b, which is a super-Jupiter about 385 light-years from Earth. As a gas giant, the planet has no rocky surface and cannot be inhabited. HIP 65426 b is more than 100 times farther from its host star than Earth is from the Sun, allowing scientists to filter light from the star and get a sharper picture of the planet itself. -same. In the accompanying paper, published on arXiv and awaiting peer review, the research team notes that this finding is important not just because of what it can teach scientists about the HIP 65426 system. b, but also because it shows that the JWST’s high-contrast imaging modes exceed expectations and open up a world of future possibilities. Aarynn Carter, postdoctoral researcher at the University of California, Santa Cruz, who led the image analysis, shared her excitement in a NASA blog post. “I think what’s most exciting is that we’ve only just begun“, Carter said.”There are many more images of exoplanets to come that will shape our overall understanding of their physics, chemistry, and formation. We might even discover previously unknown planets.”


Webb takes on the exoplanet challenge

Photographing exoplanets is an exceptional challenge because stars are brighter than planets and therefore eclipse distant worlds. About 20 images of exoplanets have already been captured by the Hubble Space Telescope and some terrestrial observatories, such as the Gemini Planet Imager. Nevertheless, this new Webb image is revolutionary in its methodology and is the first-ever direct detection of an exoplanet beyond five microns. HIP 65426 b is also estimated to be only 15 to 20 million years old – young compared to the 4.5 billion year old Earth – making it a particularly intriguing subject of study. Most exoplanets are discovered using the transit method, but this technique most often identifies larger, older planets that are likely to have undergone migration or accretion. By contrast, direct imaging can identify younger, smaller, and more Earth-like exoplanets, promising to teach astronomers new things about planetary formation. The paper also suggests such findings.”could ultimately lead to the discovery of life outside our solar system.”


In the coming days, Webb will use the lessons learned from this discovery to turn his attention to other solar systems, some of which hope to harbor exoplanets with atmospheric conditions conducive to life. NasaThe new telescope continues to illuminate the universe in exciting ways, ushering in a new era of scientific discovery.
