Check out this article from National Geographic to hear from @caganze.bsky.social and other scientists who worked hard to make the @vrubinobs.bsky.social and its massive camera a reality: www.nationalgeographic.com/science/arti...
These are first deep-space images from the Vera Rubin Observatory
The Vera C. Rubin Observatory is expected to discover 20 billion new galaxies over the next decade.

A Nice write-up by Astrobites of our preprint that went up on Axiv last week astrobites.org/2025/05/02/c...
Testing The Waters: Determining The Origin of The Cocytos Stream
How do you distinguish between home-grown and imported stars in the Milky Way? You use the Gaia space observatory, of course!

Folks who follow me but aren’t astronomers—you might not realize how MANY astronomers live in Pasadena—home to JPL, CalTech, & Carnegie Observatories, among others.

Of 3 close friends, at least 2 have lost their houses. Many non-astronomers (including support staff like janitors) have also.

I remember my first southern observing run as a young pup grad student, going out to check the sky and coming back in to tell my advisor: "It's pretty clear, just a few small clouds up in the south...."

After the Nancy Grace Roman Space Telescope launches—by May 2027—astronomers will use its images to explore what exists between looping tendrils of stars that are pulled from globular clusters to potentially reveal dark matter in greater detail than ever before: www.stsci.edu/contents/new...

Our paper has been accepted to ApJ ⬇️
Using mock observations, we show that Roman will detect gaps in streams created by subhalos with masses > 5 x 10^6 Msun in galaxies within 3 MPC, for ~1-hour exposures. Counting these gaps will help constrain the subhalo mass function. arxiv.org/abs/2305.12045
