Some parts of Mars really do change a lot between images.
Here are 2 CTX images of exactly the same region taken about 7 years apart (Dec 2007 - Jan 2015).
Lots of dust devil tracks, and wind streaks. But also, a new impact crater.

A great #PlanetaryScience animation!
Allow me to introduce myself on here! I'm a planetary scientist/astronomer at the University of Reading (UK), researching Jupiter & Saturn. I've worked at JAXA, NASA, Boston Uni and Uni of Leicester. On the side, I create space animations to share the wonders of our corner of the universe, such as:

Yay! Parker Solar Probe survived! 🪐🔭🧪 #PlanetaryScience
NASA just confirmed the Parker Solar Probe survived its closest ever passage of the Sun!
Beacon tone was received last night 🟢
We'll start getting data from the historic flyby on 1 January.

Star gazers in ancient Mesopotamia focused on recurring stuff like planetary motion, but sometimes they wrote about meteors.
Watching from Babylon, one wrote: “Night of the 7th, last part of the night, a meteor which was very bright in the middle of the sky” oracc.museum.upenn.edu//adsd/adart1...

Thanks to JWST and ground-based telescopes, NASA has refined some stats on asteroid 2024 YR4. It's about the size of a 10-story building...and also has a nearly 4% chance of impacting the Moon in 2032. Get it!

A plot of 2,108 potentially hazardous asteroids (diameter >= 140m, 19LD minimum orbit intersection distance wrt Earth). There are currently 2,479 known, which is ~40% of the estimated population. We turn up a few new PHAs per month across the sky surveys.

NEW: It’s hard to know what’s going to happen to NASA under the new administration. But one aspect of America’s space program that has long had widespread support from both Democrats and Republicans is planetary defense.
Hopefully, that stays true.

NEW: We all know JWST is a marvel of a machine that can gaze at incredibly distant stars. But I didn’t expect it be able to spy – almost by accident – small-but-hazardously sized asteroids in our backyard!
What a show off.

Even small asteroids can do a lot of damage—and new research shows the James Webb Space Telescope is adept at spotting the tiniest of space rocks.

Okay I made the jump. Still trying to figure this place out, but here is a painting of the Moon, and a picture of my cat, Luna, they are the two most beautiful things in the universe.

The Kuiper Belt contains the frozen leftovers of the formation of our Solar System. Using ALMA astronomers can observe similar belts around other stars, and they come in all shapes and sizes! What do they tell us about the formation of planetary systems?
