Here’s what happens when space junk hits the moon | Astronomy

It’s been a tough week.

The world has watched the Russian invasion of Ukraine unfold during a pandemic that still holds the world firmly in its grip after more than two years.

The attacks and resulting sanctions imposed by the US and Europe are having a huge impact – and even space is not banned. The crisis is expected to delay the launch of Europe’s first Mars rover scheduled for next September, and questions remain over NASA’s cooperation with Russia over the International Space Station.

A never-ending cycle of events that elicits despair can feel exhausting, but turning to sources of admiration in difficult times can be encouraging. When the pandemic began, many discovered a passion for the twinkling delights of stargazing.

Fortunately, the natural wonders never stop. Let’s keep exploring the inspiring world of discovery and always have hope.

Lunar Update

I’ll see you on the other side of the moon.

A rocket part was on a collision course with its surface Friday morning, moving at around 5,500 miles per hour (8,851 kilometers per hour). We may not have confirmation for some time. But what could have been a moon lemon turned into a unique research opportunity.

And don’t worry – you didn’t miss a spectacular sight since it was supposed to hit from the other shady lunar side (but we have an idea of ​​what it might have looked like).

NASA’s Lunar Reconnaissance Orbiter – which did not witness the event – will be keeping an eye out for a crater that may have formed from a possible collision. The moon has many craters – this may well be the first created by errant rocket remnants.

And tracking space junk, especially to avoid unwanted collisions, has become the passion project of none other than Apple co-founder Steve Wozniak.


You know that dramatic confrontation between Stegosaurus and T. rex in “Fantasia”? It never happened. The two highly recognizable dinosaurs never co-existed, and the time between them is longer than the time between the reign of T. rex and humans.

But the two dinos share the spotlight this week.

And, it turns out, Tyrannosaurus rex can be misunderstood. Differences between fossils of the fearsome predator may suggest there was more than one species roaming the planet, according to a new study. This means that the tyrant lizard king may have existed alongside Tyrannosaurus imperator and the slimmer Tyrannosaurus regina.

Meanwhile, a new fossil may belong to one of the oldest stegosaurs ever discovered. The specimen has a “really weird mix of features,” including physical traits that can’t be found in other stegosaurs, revealing how these armored dinosaurs evolved.

fantastic creatures

For many, pets have been the gentle, reliable pals that have helped us through the past two years of the pandemic.

They have lifted our moods, reduced our stress, and served as perfect binge-watching companions.

These simple behaviors have also been passed down to a practical scientific level. Research on the animal-human bond has exploded during the pandemic.

Pet owners say their fuzzy best friends have reduced loneliness and provided much-needed emotional support. Given that we are still living in uncertain times, the most insightful research is yet to come.


We asked for your best hiccup remedies, and boy, did you deliver.

Then we took these creative techniques to experts and tested them to see if the science backed them up.

The result? Even some of the wackiest solutions — like thinking about cows, taking a spoonful of sugar, or acting out your own Michelangelo-style “Creation of Adam” moment — actually work for a variety of reasons.

Thanks for taking the time to weigh in with so many imaginative answers. Don’t forget to bow down – and name seven men you know who are bald if you have hiccups.

The climate has changed

We lack the means to adapt to the climate crisis. That’s the warning of a new UN-backed report released this week that illustrates the widespread and disruptive impacts of human-caused climate change.

Extreme weather and rising levels of seals are altering once-familiar landscapes and could even wipe out enduring historic sites, including around 190 lining Africa’s coasts.

The Pillars of Carthage, the ruins of the Roman amphitheater at Sabratha and a 125,000-year-old coral reef are just some of the significant treasures at risk of flooding and erosion over the next 30 years.

But there’s still time to save these heritage-rich sites – and the solution is more natural than you might think.


Let’s end on these good notes:

— A tiny “flower” formation has been spotted on Mars by the Curiosity rover, and it could shed light on the history of water on the Red Planet.

— This invasive species was named using an ethnic slur. After months of decisions, the butterfly finally has a new name.

— Stonehenge may have served as an astronomically correct solar calendar. New research illustrates how it worked.
