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.

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...

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 astronomersβ€”you might not realize how MANY astronomers live in Pasadenaβ€”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.

The Vera C. Rubin Observatory is ready to transform our understanding of the cosmos The telescope will catalogue billions of new objects and produce a new map of the entire night sky every three days with the largest digital camera ever made.

Something to look forward to in 2025 www.technologyreview.com/2025/01/01/1...

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...."

An illustration. An oval disk, which represents the Andromeda galaxy, is angled, pointing to the bottom left and top right, and takes up about one third of the view. Its core appears the brightest white and is surrounded by a thinner oval that is slightly less bright white and has a few brown lines running through it. Its edges have many small blue points representing stars. A few irregularly shaped lines representing globular cluster streams are present. A fainter blue arc is at top left. To its right is a larger, somewhat wider white line that is less than half the length of the galaxy. This straighter line has a gap, and then continues in a rough triangle. Near the bottom left of the galaxy’s blue star-filled region is another streamer that looks like an arc. It also has a gap, toward its right side. More irregular, fairly dim blue lines appear just below the right side of the galaxy. The background is black.

After the Nancy Grace Roman Space Telescope launchesβ€”by May 2027β€”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
