BREAKING: ESA’s ExoMars Trace Gas Orbiter (which is designed to look at Mars itself) turned to face interstellar comet 3I/ATLAS while it passed relatively close by, at a distance of 30m kilometres.

And it caught it! Look at that adorable little puffy coma.

Update: I am now floating the theory that 3I/ATLAS keeps me from finding two matching pairs of socks.

The best part of the day is when the Sun fucks off

Well, forget what I said, turns out you can process marsrover images on the train too :)

There is a super faint smudge where comet 3I/Atlas should be. The new orbit parameters in Stellarium are a pretty good match. 🔭 #3iatlas

Oh and hey, my book about stopping killer asteroids was the runner-up in the NASW Science in Society Journalism Awards in the Books category! Thanks for the nod, @sciencewriters.org. :)

Delighted to see I've made the Notable section of the Best American Science and Nature Writing 2025 edition. Third time's a charm, or something. :) (cc: @clarakm.bsky.social)

That’s absolutely gross.

🤌🏼

Stellar stuff, no notes. :)

This year thousands of mysterious earthquakes hit Santorini. Scientists finally know why. During the quakes, researchers were able to track dangerous magma in real time.

Check out both a really exciting paper on the Santorini seismic swarm earlier this year from some of my excellent colleagues: www.nature.com/articles/s41... AND a really good write up in National Geographic by @squigglyvolcano.bsky.social: www.nationalgeographic.com/science/arti...

👀

NEW: Earlier this year, the volcanic island of Santorini was rocked by 28,000 quakes. It didn't end in an eruption—but it wasn't clear what was going on.

Now, in part thanks to AI, we know: two volcanoes were communicating using magma!

NEW: It was a delight to contribute to @quantamagazine.bsky.social's stunning new series on climate science! Naturally, my story tended apocalyptic: will Earth ever become a climate hellhole like Venus, the most extreme world in the solar system?

Nice one, @danvergano.bsky.social!

The Meteorite That Vanished: A Tale of Lies, Death and Smuggling How a space rock vanished from Africa and showed up for sale across an ocean

A meteorite's dramatic trek to Earth seems mundane compared to its sordid journey from Somalia to China: 🧪 🔭 www.scientificamerican.com/article/insi...

In the last 6 days, 9 asteroids passed inside the Moon’s orbit. Estimated sizes: ~1–38 m. All were discovered this month, a reminder that countless small, faint NEOs slip by unnoticed until they make a close pass.

That’s the one.

But wait, mini-moons aren't the same as quasi-moons, right?

Earth Has a New ‘Quasi-Moon,’ and It May Be Very Tiny

NEW: Earth and the Moon have been best mates for over four billion years. But that doesn't mean they don't want new friends!

Case in point: we just discovered an asteroid that's following Earth around! It's known as a quasi-moon. And it's adorable.

Want to Get Away? NASA Now Offers More Than 6,000 Alien Worlds to Daydream About It’s a crowded galaxy, the latest exoplanet tally shows

We've reached 6,000 confirmed exoplanets! I talked with @aussiastronomer.bsky.social about where things go from here. (A great graphic by @unamandita.bsky.social visualizes the amazing jumps in planet finds since the first ones were confirmed in the 1990s.)

Petition for this to be the actual mission patch.

Have you seen NEO Surveyor’s unofficial mission patch? :)

Yo, astronomers. Is the difference between a quasi-moon and a trojan this?

- A quasi-moon orbits the Sun in a very similar path to the planet, but is unstable, can shift about, and eventually leaves;

- A trojan either leads or trails the planet, has a stable orbit, and sticks to Lagrange points

true, but I’m also on eruptions, quakes, tsunamis and *checks notes* trying to sterilise the surfaces of entire worlds

dr apocalypse strikes again

oof, the shade
