Rubin observatory begins a 10-year movie of the changing universe | Science | AAAS 🔭🧪 @science.org www.science.org/content/arti...

The moment we've all been waiting for is finally here… On June 29, 2026, NSF–DOE Rubin Observatory officially began the Legacy Survey of Space and Time (LSST)! 🔭🧪☄️🌌 🔗: rubinobservatory.org/news/action-...

Low-Earth orbit has gotten so crowded that new NASA mission proposals need to include (and pay for, out of a limited cost cap!) three collision avoidance maneuvers, and are told to expect 1-5 potential collisions that need to be avoided.

Okay so this image (#alttext a concept painting of Y-Wings attacking the Death Star in Star Wars ) looks like it has a weird filter on it, compared to the actual painting (below). It’s an ugly blemish on an otherwise amazing book and I don’t know what to do other than grin and bear it.

Happy Pride Month everyone! 🏳️‍🌈

At #AAS248, astronomer and former IPAC Director George Helou gave a fantastic plenary talk, mapping 40 years of infrared astronomy and IPAC's pivotal role in the field. As we celebrate #IPAC40 this year, we look back on IRAS and Spitzer—and look ahead to Roman, NEO Surveyor, and the next 40 years!

Just published, and already one of my favorite stories of the year. A fascinating story expertly told by @samkean.bsky.social for @science.org

Future study of interstellar objects will build on these findings toward a better understanding of how our solar system fits into the larger picture of our galaxy. (4/4)

Astronomers used #NASAWebb’s Near-Infrared Spectrograph instrument to discover surprising details of comet 3I/ATLAS’s chemical makeup: ratios of heavy carbon and heavy hydrogen never seen among comets in our solar system. (1/4) 🧵 🧪 ☄️

One of the best things about Star Trek: The Animated Series is it had one of the coolest aliens of the franchise. Sure, the animation is "clunky" to watch, but it allowed the writers to be more creative on what kind of aliens and settings the Enterprise encounters. Kukulkan is one of my favorites.

Next month, a research vessel shaped like a bowler hat or an alien spaceship, depending on who you ask, is scheduled to depart from France for the Arctic. | Science | AAAS www.science.org/content/arti...

3I/ATLAS, the third-known interstellar visitor to pass through our Solar System, may have formed in an ancient planetary system around 12 billion years ago. The evidence presented in Nature shows that the object has a composition unlike anything else in the Solar System. go.nature.com/4aPZYVF 🔭🧪

While the scientific computing community has long been a driver of computing innovation, that is no longer possible. Today, the community must embrace the new realities of an #AI-dominated technology world, researchers argue in a new #SciencePolicyForum. https://scim.ag/3QNRM1q

Technicians met the Nancy Grace Roman Space Telescope at NASA Kennedy’s turn basin wharf and offloaded the trailer carrying the observatory from the barge, where they connected it to a truck that transported Roman to the servicing facility. #NASARoman 🔭

#PPOD: This NASA/ESA Hubble Space Telescope image of the asteroid Dimorphos was taken on 19 December 2022, nearly four months after the asteroid was impacted by NASA’s DART (Double Asteroid Redirection Test) mission. 🧪 🔭

3I/ATLAS is only the third comet ever discovered from beyond our solar system. Where did it come from? The sensitive instruments on #NASAWebb provide clues, showing its specific composition is very different than comets in our cosmic neighborhood: https://news.stsci.edu/3Qw7fDb

The evidence is mounting: this interstellar visitor is even older and weirder than anyone thought

Good new, everyone! Pirates did not capture Roman. science.nasa.gov/blogs/roman/...

Dear authors, Please use challenging words in your books/fics that my husband and I can then amicably bicker about the pronunciation of before checking our respective sources and finding we were both a little wrong. Yours truly - reader

Made some music for @tirrel.bsky.social’s awesome as hell custom designed Pinball Machine.

I need you to know that the shipping container into which the Nancy Grace Roman Space Telescope was packed for transport to the launchpad is called the Chariot, and the barge pulling the container to Cape Kennedy is called the Pegasus. So yes, this is a picture of a Pegasus pulling a Roman Chariot.
