Where the asteroid belt is located today, there was a mysterious hole in the early solar system.

If you go back a few billion years on the cosmic clock, our solar system would look very different from what it is today. The young Sun was shining like it does now about 4.5 billion years ago, although it was a bit smaller. He was enveloped in a spinning disk of gas and dust, rather than being surrounded by planets. Planets eventually formed on this disc, known as the protoplanetary disc.

Between where we are today and where the asteroid belt is today, there was a noticeable gap in the protoplanetary disk of the early Solar System. It is not known what generated the sinkhole, but scientists believe it is a sign of the processes that regulate the creation of the planet.

The discovery of this ancient loophole was detailed in a study published by a group of scientists. Cauê Borlina, doctoral student in planetary sciences. a student in the Department of Earth, Atmospheric, and Planetary Sciences (EAPS) at the Massachusetts Institute of Technology, is the lead author (). “Paleomagnetic evidence for a disk substructure in the early solar system,” reads the title of the research. It was published in the journal Science Advances.

Astronomers are increasingly studying younger solar systems that still have protoplanetary disks and developing planets through facilities such as the Atacama Large Millimeter / Sub Millimeter Array (). They often have visible gaps and rings, which are evidence of the formation of the planets. But exactly how it all works remains a mystery.

“Observations over the past decade have revealed that cavities, vacancies, and rings are prevalent in disks around other young stars,” says Benjamin Weiss, research co-author and professor of planetary science in the Department. of Earth, Atmospheric and Planetary Sciences (EAPS). “These are critical but poorly understood fingerprints of the physical processes that turn gas and dust into the early sun and planets.” Meteorites provided evidence of a gap in our solar system’s protoplanetary disk about 4.5 billion years ago.

The magnetic fields of the solar system have had an impact on the structure of meteorites. The small rocks called chondrules in the protoplanetary disc were sculpted by paleomagnetism. Chondrules are molten or partially molten round rock fragments that have accumulated into chondrites, a form of meteorite. And chondrites are among the oldest rocks in the solar system.

The magnetic fields of the time were recorded in the chondrums as they cooled. As the protoplanetary disk evolves, these magnetic fields vary. Positioning… Summary of the latest news from Brinkwire.

Astronomers have created highly detailed images of 42 of the largest objects in the solar system’s asteroid belt, including Ceres which is twice the diameter of the Grand Canyon.

The team used the European Southern Observatory (ESO) Very Large Telescope (VLT) in the Atacama Desert, Chile, to image objects that exist in the Solar System’s main asteroid belt, located between Jupiter and mars.

Since asteroids are made up of intact material that existed when the solar system was formed, the detailed images could help astronomers better understand how planets like Earth evolve.

Of the 42 main objects in the asteroid belt, only three of the largest, the dwarf planet Ceres and the asteroids Vesta and Lutetia, have been detailed so precisely before, when visited by space missions Dawn and Rosetta, operated by NASA and the European Space Agency (ESA) respectively.

“Our large ESO program provided resolved images for an order of magnitude more targets, 42 in total, allowing characterization of the 3D shape and density of a representative sample of the compositional diversity of the asteroid belt. “, scientist of the Astrophysics Laboratory of Marseille, Pierre Vernazza, said News week. “Such data was not available before and that’s what motivated us.”

Most of the objects the team photographed were over 62 miles in diameter, roughly the length of the Panama Canal. The investigation also managed to image almost all objects in the asteroid belt greater than 125 miles in diameter, which is about half the length of the Grand Canyon.

Of these, Ceres is the largest and Vesta is the second largest asteroid belt object with a diameter of just over 320 miles, five times the width of the Channel. The smallest asteroids the team photographed were Urania and Ausonia, both around 56 miles in diameter.

Vernazza, the main author of a Astronomy & Astrophysics document detailing the results, said News week how ESO’s investigation, and the new images it provided, delivered unexpected revelations regarding some of the objects in the main asteroid belt.

“There were many surprises, including the spherical shape of Hygiea and the heavily cratered surface of Pallas. Overall, this research has changed our perspective on many objects,” the researcher said.

In addition to imaging almost perfectly spherical asteroids like Hygiea and Ceres, the team also detailed elongated objects. These included the unusually shaped asteroid Kleopatra, which resembles a cosmic dog bone.

By combining details about the masses, sizes and shapes of the objects, the teams were also able to determine the densities of many asteroids in the Main Belt. They found that these densities ranged from that of coal for light asteroids like Lamberta and Sylvia, to asteroids even denser than diamond, like Psyche and Kalliope.

The discovery of such a wide range of densities in the main belt asteroids indicates that some of these objects may have drastically different compositions, which could have implications for our understanding of the early solar system.

“We now have a better understanding of the variety of composition of the asteroid belt, the effect of large impacts on asteroid shapes, binary formation and the overall dynamic evolution of the solar system,” said declared Vernazza.

Such detailed images of asteroid belt objects were only made possible by the sensitivity of the Spectro-Polarimetric High Contrast Exoplanet REsearch (SPHERE) instrument mounted on the VLT.

“The angular resolution of the SPHERE instrument is about three times better than that of the Hubble Space Telescope,” Vernazza said. “We knew that the improved capabilities of SPHERE as well as the fact that little was known about the shape of the larger asteroids in the Main Belt would allow us to make substantial progress in this area.”

To get even more detailed images of these major objects in the asteroid belt, astronomers may have to wait for the completion of the Extremely Large Telescope (ELT), which is currently under construction in Chile and is expected to start operating later. this decade.

“We will have to wait for the next big step, namely the first light of the ELT,” concluded Vernazza. “In the meantime, we will continue to use the SPHERE instrument on targets of interest that were not covered by our observing program.”

Researcher at the Marseille Astrophysics Laboratory and co-author of the article, Laurent Jorda declared News week: “In the near future we plan to observe some more interesting asteroids
with SPHERE to answer new questions raised by our major program.

“When it becomes available, the ESO / E-ELT will allow us to solve a
largest sample of asteroids in the main belt and possibly even the
the largest objects in the very distant Edgeworth-Kuiper belt beyond Neptune. “

On the heels of the Hope Mars mission, the United Arab Emirates have announced that they will begin building another interplanetary probe to be launched in 2028, with the aim of visiting Venus and seven worlds in the asteroid belt over the next 12 years.

The mission, announced on Tuesday by UAE Vice President Sheikh Mohammed bin Rashid, will fly over the second hell planet from the sun in mid-2028, circling the planet on its way back from Earth and towards the asteroid belt. . It will be built over the next seven years and its journey will allow it to accumulate over 3.6 billion kilometers (over 2.2 billion miles).

“The UAE is committed to making a significant contribution to space exploration, scientific research and our understanding of the solar system,” tweeted Sheikh Mohamed bin Zayed, Crown Prince of Abu Dhabi, Tuesday.

The goal of the mission will be to explore seven objects in the Asteroid Belt, a region of space between Mars and Jupiter stacked with millions of oddly shaped rocks orbiting the sun. Objects inside the belt have been studied by space agencies, like NASA, in the past, but the UAE’s ambitious mission will aim to image seven asteroids and then hit one to take a sample.

If they can achieve all of this, the UAE would become the fourth country to touch the surface of an asteroid. It won’t be easy.

“This mission is on the order of five times more complex than the EMM,” Sarah bint Yousif Al Amiri, president of the United Arab Emirates Space Agency, said in a press release.

As with the Hope mission, the United Arab Emirates agency will work with the Atmospheric and Space Physics Laboratory at the University of Colorado at Boulder. The name of the mission will be announced later.

Venus has become an increasingly popular target for space missions over the past year. NASA plans to launch two spaceships on the planet, and the Indian Space Agency and the European Space Agency are also preparing their own probes to explore it.

While many explorers of Venus have been the subject of discussion for years, there has been a lot of hype about its potential habitability since. 2020 study found high levels of phosphine – a gas associated with life on Earth – in the clouds of the planet greenhouse. Since publication, the results have been disputed and the data reanalyzed, with a June 2021 study suggesting the planet’s atmosphere is too dry to support microbial life.

(MENAFN- Jordan Times) DUBAI – The United Arab Emirates will launch a spacecraft to explore a major asteroid belt between Mars and Jupiter, officials said on Tuesday, after a United Arab Emirates probe reached the Red Planet in beginning of this year.

The five-year journey from 2028 will traverse 3.6 billion kilometers, as the unmanned vehicle relies on gravitational aids from Earth and Venus to reach the main asteroid belt beyond Mars, have officials said.

“The mission will conduct its first close planetary approach to orbit around Venus in mid-2028, followed by close to Earth orbit in mid-2029,” the United Arab Emirates Space Agency said in a statement.

“It will make its first flyby of a main object in the asteroid belt in 2030, then observe a total of seven asteroids in the main belt before its final landing on an asteroid 560 million kilometers from Earth in 2033.”

The United Arab Emirates – made up of seven emirates including the capital Abu Dhabi and Dubai – is a newcomer to the world of space exploration.

In September 2019, the oil-rich country sent the first Emirati into space as part of a three-member crew that took off aboard a Soyuz rocket from Kazakhstan.

Then, in February 2021, its “Hope” probe successfully entered orbit of Mars on a journey to reveal the secrets of Martian weather, during the Arab world’s first interplanetary mission.

The UAE also plans to send an unmanned rover to the moon by 2024.

Abu Dhabi Crown Prince Mohammed Bin Zayed, UAE’s de facto ruler, said the launch of the new project sets a new “ambitious” goal for the country.

“The UAE is determined to make a significant contribution to space exploration, scientific research and our understanding of the solar system,” he tweeted.

The United Arab Emirates Space Agency (UAE) is embarking on a new space mission in collaboration with CU Boulder’s Atmospheric and Space Physics Laboratory (LASP). The mission will build on the success of the UAE’s ongoing Emirates Mars mission to visit a much more ambitious target: the asteroid belt.

Like their comet and Kuiper Belt cousins, asteroids are small rocky bodies that archive gases and dust present during the early stages of our solar system’s formation. Although researchers have studied these minor planets using terrestrial and space telescopes, the small size of the asteroids and their great distance from the sun have limited our ability to understand their volatile materials and their extraordinary supply of minerals. The international team plans to build and deploy a state-of-the-art instrument suite to collect the data needed to reveal the history of several asteroids and uncover their future potential as space resources.

“The Asteroid Belt is an exciting research opportunity that encompasses the scientific, engineering and mission operations capabilities of LASP while aligning with the aspirations of the United Arab Emirates Space Agency to advance our understanding of our solar system, ”said Pete Withnell, LASP program manager. “This new mission will build on our successful knowledge partnership between engineers and scientists from both countries and provide ample opportunities to develop new cutting-edge technologies. ”

Transformer change

The new mission will build on the transformative change that has taken place in the UAE’s space sector with the aim of making a significant contribution to space exploration. This was catalyzed by the Emirates Mars Mission (EMM), the first Arab mission to another planet, which resulted from a foundational collaborative partnership between the UAE’s Mohammed Bin Rashid Space Center and LASP at CU Boulder. This collaboration led to the successful launch, orbital insertion and continued data collection of EMM.

“Partnering with the United Arab Emirates Space Agency for this new mission will push the boundaries of scientific discovery while enhancing scientific knowledge and advancing critical engineering skills,” said Dan Baker, Director of LASP. “This is a unique opportunity to learn more about the beginnings of our solar system while helping to inspire a new generation of students studying science, technology, engineering and math in both countries. “

“The new mission we are mounting to explore the asteroid belt takes us to another level of complexity and capability development, and represents a quantum leap for the development of the UAE space sector,” said Sarah Al Amiri, Minister of the United Arab Emirates. Technology and President of the United Arab Emirates Space Agency. “It is also both the continuation and the deepening of the collaboration between Emirati engineers and scientists and the University of Colorado, which has been instrumental in our work to accelerate our space sector.”

The mission will include a significant element of private sector participation, with a series of initiatives launched to encourage both emerging Emirati space startups and the growing specialization of existing companies involved in areas such as avionics and manufacturing to move forward. focus on the country’s developing space sector.

“With this mission, we are focused on leveraging our work with CU and LASP to foster our private sector, using our academic partnership to translate into real value creation and economic opportunity,” Al Amiri said. “We can already see tremendous synergies between Colorado’s vibrant space community and the emerging industry here in the Emirates.”

“The partnership between CU Boulder and MBRSC on the Emirates Mars mission serves as a proven model of international collaboration in academic research that transcends borders and cultures, fosters innovation and generates lasting benefits globally,” said Terri Fiez, CU Boulder Vice-Chancellor for Research and Innovation. “This ambitious new mission with the United Arab Emirates Space Agency will accelerate transformational discoveries with real impact.”

LASP is a world-renowned research institute at CU Boulder that engages in the full cycle of space exploration, from conception to instrument and satellite design, mission operations and scientific discovery. In addition to its involvement in numerous interplanetary missions, the Lab has played a leading role in the development of small satellite technologies to answer key scientific questions. LASP, which began a decade before the creation of NASA, is the only university research institute in the world to have sent instruments to the eight planets and to Pluto.

Using data from NASA’s Asteroid Terrestrial-Impact Last Alert System (ATLAS) survey, astronomers have detected a comet in the main asteroid belt, an unusual location for comets. Named asteroid (248370) 2005 QN137, the body of the solar system was earlier identified as the eighth asteroid in the main belt and discovered in 2005. But on July 7 of this year, astronomers were surprised to discover that the space rock had grown a tail, a property exhibited by comets.

Unlike asteroids, which live primarily in the main asteroid belt orbiting the sun between the orbits of Mars and Jupiter, comets primarily live in the Kuiper Belt, an orbit that exists beyond Neptune – the planet. furthest from our solar system – and is 20 times wider than the main asteroid belt.

Comets are much smaller space rocks than asteroids and due to their small masses they follow long elliptical orbits sometimes going very close to the sun. After living in the cold depths of the Outer Solar System for hundreds and thousands of years, they enter the Inner Solar System and as they approach the Sun their surface evaporates leaving a trail of dust and giving them their characteristic appearance.

In 2006, astronomers David Jewitt and Henry Hsieh discovered that small asteroids in the main asteroid belt could also develop comet-like properties, such that their ice could sublimate and exhibit a dust tail. Jewitt and Hsieh called them main belt comets.

Now, Hsieh has discovered that the Main Belt Asteroid (248370) 2005 QN137 meets the physical definition of a comet because it is icy and throws dust into space despite following orbit. of an asteroid. “This duality and blurring of the line between what were previously thought to be two completely separate types of objects – asteroids and comets – is a key part of what makes these objects so interesting,” Hseih said in a statement. The head of the recently observed Main Belt comet is 3.2 kilometers in diameter while its tail is 720,000 kilometers long. The width of the tail is 1,400 kilometers wide.

The results were published September 30 in Earth and Planetary Astrophysics.

The United Arab Emirates Space Agency (UAE) will send a probe into the asteroid belt between Mars and Jupiter, with the goal of eventually landing on an asteroid in the early 2030s, in a mission that is sure to be a blow. major thumb for the country. private sector space companies.

The mission will launch in 2028. From there, the spacecraft will make a long and winding journey: it will travel 3.6 billion kilometers over five years, boomeranging around Venus and Earth to create sufficient speed to finally reach the asteroid belt beyond Mars in 2030 The UAE aims to land the spacecraft on an asteroid in 2033 – an ambitious goal for a country that only founded its space agency in 2014 .

If successful, the UAE Space Agency would join a very small group – including NASA, the European Space Agency, and the Japanese space agency JAXA – to land a vehicle on a planetoid. The exact scientific goals of the mission will be announced next year, but all the data the spacecraft collects could help deepen our understanding of the origins of the universe. This is because some scientists believe that asteroids are celestial remnants of the formation of the solar system.

This is the UAE’s latest and most ambitious effort, which aims to boost its national space sector. Importantly, the UAE will give priority access to contracts and procurement to UAE companies, which will benefit from the project.

Last year, the country launched the Emirates Mars Mission Hope probe, which entered orbit around Mars in February this year. This probe will spend a Martian year (687 days) in orbit around the red planet and collect data on its atmosphere.

The United Arab Emirates will also send a 22-pound lunar rover, dubbed Rashid, to the moon in 2022. This payload, which also includes technology from three private Canadian companies, will be delivered aboard the Hakuto-R lander of the Japanese space startup ispace.

Sarah Al Amiri, president of the United Arab Emirates Space Agency, said the new mission would be “on the order of five times more complex” than the mission to Mars. New challenges will include “the design and engineering of spacecraft, interplanetary navigation and the integration of complex systems”, as well as the higher performance requirements of the communication, power and propulsion systems of the spacecraft, the United Arab Emirates said in a statement.

NASA has already encountered the gigantic asteroid during its previous missions. In 2011 and 2012, Vesta was visited and examined by the space agency using a spacecraft named Dawn. Dawn’s initial examination includes identifying Vesta’s physical structures.

Among the details collected on the asteroid are the exceptional depressions of Vesta scattered over its entire surface. The largest hollows identified were the Divalia Fossae, occupying more than 50% of the surface in the middle of the cosmic rock, and the Saturnalia Fossae, bumpy in the northern area.

The Divalia and Saturnalia Fossae are confusing to experts, as there is little data to show how the two largest hollows came into existence and what materials are responsible for the massive asteroid dent. Experts’ best bet is that the dips are the result of a strong cataclysmic collision between Vesta and one of the large objects in our solar system.

University of Georgia geology expert and study co-author Christian Klimczak said in a space report that Vesta was apparently in the process of becoming an Earth-like planet.

However, planetary formation was disrupted early in the solar system. The expert said research on Vesta could help us better understand what really happened during the asteroid’s early years and learn more about the details of the origin of our planet.

The Dawn spaceship has discovered the solar system’s most intractable puzzle

Dawn’s discovery of the couple of hollows on Vesta’s body has led scientists to theorize whether the other basins on her surface, known as Rheasilvia and Veneneia, have some connection to the asteroid’s origin.

To analyze the puzzling characteristics of the asteroid, experts chose a standard approach called crater counting. The method will determine and consolidate the impact categories of Vesta crater, ranging from oldest to youngest, as well as the correct sequence of the series of impacts inflicted on the surface.

The exact date cannot be accurately determined by the crater counting approach. However, it can arrange consecutive impacts in order from old to new craters.

Counting the craters, the best way to analyze the asteroid, did not provide complete information about the interval between craters, as they turned out to have existed due to their similar age. Although of the same age, the maps of the craters of Vest were not correlated with each other.

Further research will be conducted regarding the seemingly insoluble case of the asteroid Vesta and the connection of its hollow and austere features. The research was published in the journal Icarus, titled “Age Relationships of Large-scale Troughs and Impact Basins on Vesta”.

They are generally much redder than the asteroids in the main asteroid belt because they have more complex organic materials covering their surface.

The 2 reddest asteroids

The main asteroid belt between Mars and Jupiter is estimated to contain more than a million objects over a kilometer in diameter. Plus, there are millions of smaller pieces of rock debris in the belt, all swirling around the sun. And, for the most part, these millions of asteroids are quite similar in composition and appearance. But now, with new observations, astronomers say they’ve found two asteroids in the belt that, frankly, shouldn’t be there. These rocky bodies are the two reddest asteroids ever seen in the asteroid belt.

Peer review Astrophysics Journal published the new work on July 26, 2021. The Japan Aerospace Exploration Agency (JAXA) announced the discovery in a press release on July 27. Veteran science writer George Dvorsky featured it in an article in Gizmodo on July 30.

Rich in organic matter

The intriguing discovery was made by astronomer Sunao Hasegawa and his team at the Japan Aerospace Exploration Agency (JAXA). Asteroids as red as these – 203 Pompeja and 269 Justitia – are generally not seen in the asteroid belt. This is because asteroids closer to the sun have little organic matter on their surface, while asteroids further away are covered with complex organic matter. These are believed to be produced from simpler organic compounds like methane and methanol ice.

Other low albedo asteroids in the belt, called D-type asteroids, have long been considered the redder. But it seems that is no longer the case.

Transneptunian objects?

For this reason, researchers believe they could be transneptunian objects (TNO), asteroids that inhabit the distant outer solar system beyond Neptune. Their surface composition is very similar to that of the NWT. According to the paper:

These two asteroids have a redder spectral slope than any other D-type body, which are the reddest objects in the asteroid belt. The spectroscopic results suggest the presence of complex organic materials on the surface layer of these asteroids, implying that they could have formed near Neptune.

But then, how did they end up in the main asteroid belt?

Researchers say these objects likely drifted inward when the solar system was still young. It’s not clear exactly why this happened, but it does indicate that the early solar system was a very chaotic place.

The first of many?

Because these objects are so much redder than the typical asteroids in the main belt, they stood out like a sore thumb. It seems likely that they are also more numerous. It could be that many of the main belt asteroids actually originate from further out in the solar system. If so, identifying them could provide valuable clues to the formation of the early solar system.

The main asteroid belt, therefore, can be a mixture of asteroids that formed closer to the sun and others that drifted from elsewhere. The solar system can be a messy place.

Cataloging large asteroid populations

The two unusually red asteroids were noticed following a new study to catalog the composition and distribution of large asteroids in the main belt. The installation of the NASA infrared telescope (IRTF) and the Seoul National University (SAO) astronomical observatory were used in this effort. Scientists from MIT, the University of Hawaii, Seoul National University, Kyoto University and other institutions collaborated on the study.

203 Pompeja and 269 Justitia are both larger asteroids, so they were included in the observations. The 203 Pompeja has a diameter of 68 miles (110 km) and the 269 Justitia is about half its size.

The surprising discovery of these red asteroids, and possibly more in the future, will provide valuable clues to the formation of the early solar system. It was a chaotic place back then, maybe even more than initially thought.

The future

There is also another bonus. If some TNOs found their way to the asteroid belt, then it would be easier to study them with future probes. NASA’s New Horizons probe is currently exploring the distant Kuiper Belt beyond Neptune. But studying some TNOs up close can now be as easy as traveling to the asteroid belt, which is much closer. A probe could study the two the typical bodies of the asteroid belt as well as the NWT.

Bottom line: Astronomers have discovered two asteroids in the asteroid belt between Mars and Jupiter that are much redder than any of their neighbors. Researchers say they likely migrated inland from the far reaches of the solar system.
