Spent last week on Mars (in Utah) helping out with the University Rover Challenge, which continues to be one of the coolest things I am involved in.

the observatory at last defeats its ancient enemy

Shoutout to the very senior professor in HCI who gave a talk last month about how AI can do qualitative data analysis better than people now.

All of this. For always.

Earth eclipses the Sun as seen by Artemis II on Orion. Satellites showing off as usual...

I absolutely hate this framing. The fact that the US press has refused to so much as glance in the direction of progressive Christians over the last thirty or so years doesn't mean anyone was sleeping, it means we have an incredibly lazy press.

Ooohhhh, new #supernova alert! ⭐💥 Get your telescopes out and pointed towards this edge-on galaxy! EvenSeeStar S50 is capable of imaging it (second pic) SN SN 2026kid in NGC 5907 www.wis-tns.org/object/2026kid 🔭 #Astrophotography 📸 R. Sears / Ballico

And the woman did speak unto the hound, saying, What do you mean, normal men, and the hound answered the woman, saying, We are just innocent men. And great was her emotion

I'm one of those trans women. I worked ground ops for Artemis I. I am torn between celebrating the success of my friends and peers and grieving how my dream of working for NASA was shattered by hateful assholes in Tallahassee

Splashdown!! I'm so relieved and happy I could cry. The Artemis II coverage has been such a wonderful source of joy and delight over what's personally been an incredibly difficult ten days for me. I'm so very grateful for it.

Reid: We have a great view of the moon out of window 2. Looks a little smaller than yesterday. Jackie: Guess we’ll have to go back.

Safe trip back, Integrity!

Artemis II is rapidly closing towards your location (Earth).

*heavy sigh in high-energy/UV astrophysics* Time to bother my reps again.

#Artemis II - We have the first image from yesterdays Lunar flyby captured by the crew on Orion EARTHSET. April 6, 2026. Humanity, from the other side. First photo from the far side of the Moon. Captured from Orion as Earth dips beyond the lunar horizon. 🚀🌕🌍

Spiritually I am the pot of Nutella flying across the Artemis II Orion cabin.

Delightfully surprised by the appearance of some compact object friends in here, including the Crab pulsar, HLX-1 (!) and Sgr A*. Really cool to see different kinds of objects sat beside things of a similar size scale that you might not have expected. Boggled at just how big hypergiants can get!!

I downloaded the high-res version of this amazing picture from the Artemis crew and did a little edit to make it look more like what the astronauts might actually see! Enjoy the picture and then check out the thread below explaining what you’re looking at… 🧪 #artemis #artemisii #space #moon

More context on this #Artemis II image: * This is the night side, lit by moonlight. You can see city lights in Spain & Portugal, & a sliver of day at lower right * The Sun is entirely behind Earth, which makes it a kind of solar eclipse, but w/ Earth doing the eclipsing instead of the Moon: ☀️🌍🚀🌕

sorry have to add my favorite one

GO #ARTEMISII GO!!!! 🚀 Godspeed, humans!

Artemis II is go for launch! T-10 mins and starting the countdown soon! www.youtube.com/live/Tf_UjBM...

The Supreme Court’s decision today in Chiles v. Salazar is a devastating step backward that will cause real harm to American children and families. By weaponizing the First Amendment, the Court has elevated anti-LGBTQ+ bias over the safety, health, and wellbeing of young people.

"We have centuries of accumulated pedagogical wisdom telling us that the attempt, including the failed attempt, is where the learning lives. And yet, somehow, when it comes to AI agents, we've collectively decided that maybe this time it's different."

The world is full of horrors right now but they can't take away my joy to finally see humans go back to the Moon. Yay spaceflight!!!

There is no separating art from the artist when the artist is determined to use every penny of her fortune to destroy the lives of trans people. Don't touch it. Our lives are more important than your nostalgia. Watch literally anything else.

Happy International Women's Day! Perfect time for me to (re)share our white paper on increasing the retention of women in professional astrophysics (really full of suggestions that broaden participation in academic science in general). arxiv.org/abs/2512.24465 🧪🔭☄️👩‍🔬

It turns out the U.S. did a “double tap” attack just as emergency responders were arriving at the girls’ elementary school. This is what the Russians do routinely in Ukraine. That’s a war crime under international humanitarian law.

"Every person is a human being, whose personal development is more important than our short-term scientific accomplishments" - and more bangers in this from David Hogg (spoiler: it's about AI!) arxiv.org/abs/2602.10181 🔭

"This process is also open to those outside the United States who may be impacted by a proposed system." Thank you @aas.org! It's *important* that global communities are able to have a say in a global commons - the sky we all share. USA FCC granting spectrum allowance for 1M impacts us all. 🔭

Fun to be seeing the word UVEX a lot in the Winter Olympics coverage, even if it's a company that makes helmets and goggles rather than our space telescope in development 😂

Yesterday, five-year-old Liam and his dad Adrian were released from Dilley detention center. I picked them up last night and escorted them back to Minnesota this morning. Liam is now home. With his hat and his backpack.

BREAKING: The Senate just blocked a bill that would have renewed ICE's budget without real, enforceable changes. This is a direct result of hundreds of thousands of people across the nation demanding that our Senators vote no.

It’s -9 degrees. Downtown Minneapolis is packed for the anti-ICE rally and the crowd keeps growing

Most gamma-ray bursts last seconds to minutes and are associated with the explosive death of a massive star. However, GRB 250702B in July 2025 lasted hours to days, causing astronomers to wonder what could produce an explosion that just wouldn’t stop. 🔭🧪🛰️ nustar.caltech.edu/news/nustar2...

Congress must immediately act to impeach & imprison Donald Trump. And if they fail to do so, the rest of the world should punish the USA just as heavily as was done to Russia for attacking Ukraine. We should not get to kidnap heads of state & "run" sovereign countries like vassals.

Wake Up Dead Man was definitely the film I needed to see right now. Excellent stuff, and worth going to the movies for!

Here is a stunning image of Interstellar Comet 3I/ATLAS, taken on Dec. 2 by astrophotographers Gerald Rhemann and Michael Jäger, showing the comet's long wispy plasma tail in full glory and a dusty anti-tail. www.facebook.com/groups/22700... #Astronomy 1/n

This is extremely bad and worrisome for obvious reasons, but it's worth pointing out that this was obviously the student's goal She knowingly wrote a garbage essay for her trans prof's class and when she obviously got a terrible grade stirred up a media storm This was clearly the intended outcome

It's Friday, and apparently bluesky is ready for this fun revelation: Dinosaurs lived on the other side the Galaxy.

Very excited to share the NASA/ESA/STScI press release of our team's work on Apep! It's a terrific writeup, complete with a brand new beautiful visualisation of the nebula geometry. 1/? ⚛️🔭🧪 science.nasa.gov/missions/web...

What happens when a supermassive black hole takes a bite of a giant star? It glows brighter than 10 trillion suns. Profs. @saavikford.bsky.social and @bmckastro.bsky.social helped uncover this mind-bending feast in Nature Astronomy

I want to explain a few things and then it might be clearer why UK trans people are upset. In 2001 I married my wife, Sylvia. In 2005 I started medical transition. (1/13)

Actual good news about a NASA science mission! 🔭
