Cool, wind-shaped rocks on Mars photographed yesterday.

SpaceX shifts focus from something that it will never do on Mars to something it will never do on the Moon.

I'm hardly the first person to note this, but it's enormously instructive that our President and his followers saw the message "THE ONLY THING MORE POWERFUL THAN HATE IS LOVE" and understood it, correctly, as an attack on them

If you ever wanted to see what Jurassic Park would look like with dead-eyed, uncanny-valley actors, that ad was for you.

Bad Bunny “together we are America”

That was an absolute celebration of joy. Damn

YOU'VE SWITCHED OFF YOUR TARGETING COMPUTER!

This is Earth and the Moon, photographed by a spacecraft in Mars orbit.

Fair play to the organisers of the Winter Olympics 2026 for accurately depicting Mars in the Opening Ceremony.

In which Jeffrey Epstein, who laundered money for the Russians, explains how Donald Trump was doing exactly the same thing, and how this accounts for most of his wealth.

Saturn. By Cassini.

No joke: I got angry hate mail today for writing an obituary of a Black woman scientist—because the person felt she did didn’t deserve the recognition. Which just makes me want to share it again: www.nature.com/articles/d41...

This is a cool photo of crescent Venus. And the Moon, too. Image credit: Iván Éder

I had a fun conversation last week with @planetarysociety.bsky.social's Planetary Radio host Sarah Al-Ahmed about our recent Europa seafloor paper! Check it out: www.planetary.org/planetary-ra...

Here's who the Washington Post just laid off.

A staggering statement from former Washington Post editor Marty Baron: "This ranks among the darkest days in the history of one of the world's greatest news organizations."

“.. Not a single Republican member of Congress showed up to the public forum .. on the violence inflicted by federal immigration agents, featuring testimony from the brothers of Renee Good ..” @newrepublic.com newrepublic.com/post/206100/...

The French are taking none of Musk’s bullshit.

Cool photo down from Mars earlier today.

I love to see this. But I have absolutely zero regrets leaving Twitter, given what it degenerated into.

A reminder that the Kennedy Center is the literal and legal and congressional designated presidential memorial to JFK. This would be like Trump tearing down the Lincoln Memorial to build something “better.”

May the Epstein files remind every woman that she should not feel beholden to beauty standards established by men who are attracted to children.

The funny thing about a certain type of angry conspiracy guy is that they’re literally being confronted with an elite paedophile ring and a tyrannical government at the same time right now, and because it isn't being done by the people they wanted it to be done by they’re all being pussies about it

These were the people who held the careers of female scholars in their hands . This is who was shaping or epistemological world

Jezero Crater, Mars, earlier today.

Elon Musk publicly slandering that cave diver as a "pedo guy" after he begged Jeffrey Epstein for island party invites is just incredible

Here's another deep field image from JWST. There's something pretty amazing hidden within it, which I'll talk about next. But open up this image and lose yourself in this almost impossibly vast view of our Universe. The six-pointed features are stars in the Milky Way. Everything else is a galaxy.

This image came down from the Curiosity rover on Mars a couple of days ago.

Time to post this rather incredible photo again. The largest volcano in the Solar System, Olympus Mons, with one of the Solar System's smallest moons, Phobos, crossing it. Photographed from Mars orbit. Credit: Credit: ESA/DLR/FU Berlin/Andrea Luck @andrealuck.bsky.social CC BY

After being held in two of them as a boy, I fought for decades urging America to never again build concentration camps and put human beings in them. It breaks my heart to watch this happen twice now in my own lifetime.

Wow. This is devastating. www.science.org/content/arti...

This hit so fucking hard today.

A lot of Dems are going to take Bovino and Noem being fired as the finish line, and it's very important to make it clear to them that it is a starting line

The officer who shot Alex worked for DHS for 8 years. The officer who shot Renee worked for DHS for over 10 years. Both are considered “highly trained.” The problem isn’t "training." DHS was built to violate our rights and has been empowered to act with impunity. We must MELT ICE and dismantle DHS.

The biggest risk in this moment is something sociologists call “symbolic compliance.” That’s when an institution that is violating civil rights gives the public just enough symbolic victories that accountability efforts lose steam before there has been any meaningful change.

SHOCKINGLY my abstract for LPSC 2026 was not accepted
