I can’t think of a better reason to finally join Bluesky - my first first-authored paper is out! It being published in @science.org is surreal. This was a community effort in every sense, led by an incredible team with @rosvall-lab.bsky.social @mathcancer.bsky.social @juncowren.bsky.social

Shutdown Continues With No Immediate End in Sight spacepolicyonline.com/news/shutdow...

I think Perseverance may have spotted interstellar comet 3I/Atlas last night from Mars!

After stacking 20 images from Mastcam-Z, I found a faint smudge of light in the constellation Corona Borealis close to the location where the comet was expected. 🔭

NEW: In newly unsealed testimony, a SpaceX insider revealed that Elon Musk’s company had directly received money from Chinese investors, raising questions about foreign ownership interests in one of the United States’ most important military contractors.

"If we lose hope, we're doomed."

We must continue Dr. Jane Goodall's mission and all fight for the future of the planet.

Ed's right. Again.

A recent vista from Mars obtained by the Perseverance Rover on its 1635th Martian day, or 'Sol', Clouds far above the eternal dust pall are unusually well shown in this afternoon view. This is a mosaic of two wide angle color Navcam images.

For all the great space events on tap this week, the potential government shutdown at 12:01 am Wednesday is top of mind.

And, if anyone was wondering about the "science leaving Twitter for Bluesky" trend... the first 24h of this paper on altmetric:

EarthCARE is a inexhaustible source of beautiful imagery of some of the most spectacular phenomena nature has to offer, so I've started a Gallery page on the EarthCARE Science web site, showing for example convective motions in the trainbands of Typhoon Ragasa... www.earthcarescience.net/gallery

Yesterday Curiosity took pix of jagged peaks in the distance with its ChemCam. I stitched them together, did some work on them, and... just look at that view... I've been doing this since Sojourner landed & this is one of my fave images ever... Credits: NASA/JPL-Caltech/LANL/S Atkinson

I've been asked a few times over the last few days what I think the chances are that the "leopard spots and poppy seeds" on Mars will turn out to be actual evidence of life. People are naturally skeptical given the history of possible signs of life on other planets. Strap in: long thread ahead...

Groundbreaking new image! The EHT reveals the dynamic environment around black hole M87*.

The 2021 image shows a distinct shift in polarization patterns, tracing changes in magnetic fields near the event horizon.

Speak Out While You Can
As you ponder protests, policies, and how everyone should respond, re-read this part of the Executive Order that erases NASA’s union rights. It redefines what NASA is – despite whatever wording is in its charter nasawatch.com/activism/spe...

We observed the habitable zone planet TRAPPIST-1e with JWST to search for an atmosphere.
