A serene celestial scene with soft and subtle blue clouds and a scattering of stars. The three brightest stars are nestled within a central hollow of the nebula. Their light gently reflects from the nearby cloud rim, shadowing into a vignette at the periphery. A few of the stars stand out with an orange glow. There is a tiny but noteworthy orange "hamburger" of an accreting star in the left half of the image. Looking closer, one can see the "buns" are actually broad cones of light and the "patty" is the shadow of the accreting disk of dust. The star itself is unseen. This is actually the subject of study for the image.

Worked on this yesterday with my new found free time with the kid starting school.

I realize broad science-literacy problems cannot generally be solved just by shoving more facts at people but I really wish more people understood that the entire purpose and mechanism of a vaccine is to educate your OWN immune system, making it about the most "natural" medical intervention possible

Tanya Harrison: Roving on Mars - Eos This planetary geologist has worked on nearly every Mars rover while connecting government, universities, the private sector, and the public.

Thanks for sharing a bit of my career story! 🧡

I love my SpaceX Inspiration4 spacesuit & can’t believe she’ll be on display in the Smithsonian Air & Space Museum next week in the new Futures in Space exhibit. I’ll be there Monday from 11-12 for a Q&A with Space History curator Emily Margolis. Come say hi! 👋🏾👩🏾‍🚀🚀🙏🏽

I never used one when I lived there either for that very reason. 😂 But these days it comes in handy when I have to travel for work carrying around a bag with electronics gear in it. And with the annoyance of wearing glasses in the rain.

"...anyone who actually understands LLMs knows that it can’t achieve new ways of thinking. It’s just putting together words in the most statistically likely way, forming connections that may sound like a well-thought-out argument but are actually not...'intelligence' as humans would define it."

Creative work in general pays far less than people think it does, especially relative to the notability one can have. The correlation between "fame" and "income" is rather shaky, especially the further down you go on the fame power curve. Lots of "world famous" creators are broke as hell.

I got one of these the first time around and can say, being from the rainy Pacific Northwest, it's legit the best umbrella I've ever owned. 10/10 would recommend if you're in the market for an ultra-nerdy umbrella! ❤️

New insights into the origin of ice: chronological implication from 14 permanently shadowed craters on Mercury The polar regions of Mercury are characterised by areas known as permanently shadowed regions (PSRs), which provide stable thermal conditions for wate…

Permanently shadowed craters on Mercury: amazing results!

• Older polar craters host more ice, suggesting steady-state processes drive long-term accumulation.
• Younger radar-bright craters imply recent resurfacing
• Two young, ice-rich craters suggest episodic delivery from comets or asteroids. 🧪

Under attack: How humanity is losing the night sky Losing the dark isn’t just about the stars. It has dire consequences for human health as well as the natural world.

Light pollution, both on the ground and from megaconstellations, is cutting us off from one of the only universal things humanity shares across the globe: Visual access to the night sky. And it has serious biological, scientific, and cultural consequences:

I was a NASA Space Grant Student in my junior year of undergrad, it was through this program that I really started to see what a career in planetary science could look like and where I could fit within it.

I was a NASA Space Grant recipient for earth sciences (seismology!) and rocket payload systems during my junior year because I wanted to explore more of space.

Opportunities like this MATTER.

I have never been so proud to be a UW Astro alumna. 😂

At a Star Trek convention ages ago, I was standing at the front of a line to get past a curtain into an event. Mark Alaimo (Gul Dukat) popped his head out of the curtain, looked at me, and asked if I could grab him a coffee if he gave me $5. I absolutely said yes and acquired said coffee.

This is a solar eclipse.

That moon is the little space potato Phobos. And you can even see sunspots!

At CUNY we’ve routinely used Space Grant funds to pick up extra students who appear ‘out of cycle’ for our undergrad programs, or for bridge funding for PhD students (where advisors have 3yr grants that don’t get renewed or have a grant about to start)… not to mention the 2yrs they funded us for a

That's so cool!

i was a two-time nasa space grant fellow during my phd. in addition to supporting my cosmology research (weak gravitational lensing), i did outreach in local public schools, and helped design two special astronomy exhibits for the science museum (exoplanets & comets).

How laypeople evaluate scientific explanations containing jargon - Nature Human Behaviour Cruz and Lombrozo examine how laypeople make sense of scientific explanations and find that although jargon reduces understanding, for short explanations, jargon makes the explanation more satisfying.
