Thanks to Dr. Nicky Fox, Associate Administrator for NASA's Science Mission Directorate, for stopping by @ucbssl.bsky.social to see COSI being assembled at the lab. Hopefully you’ll enjoy building the LEGO COSI at home!

COSI is coming together! @ucbssl.bsky.social’s senior aerospace engineer Christopher Smith and aerospace instrumentation mechanical engineer Matt Rubly recently assembled the mission’s 16 germanium detectors.

Congrats to Isidro Pena, an undergraduate research assistant at SSL who works on the @cosi-explorer.bsky.social! Pena was one of the undergraduate winners of the Chambliss Astronomy Achievement Student Award poster competition at the 248th meeting of the @aas.org! 🙌🎉🧪🔭 aas.org/posts/news/2...

Congrats to Nicolas Lopez, graduate student at George Washington University and research assistant on the COSI mission! Lopez was one of the graduate winners of the Chambliss Astronomy Achievement Student Award poster competition at the 248th meeting of the @aas.org. Way to represent the mission🙌🎉!

COSI was covered in this article published by @us.theconversation.com. One of COSI’s science objectives—to seek out the source of the gamma ray signature of matter/antimatter annihilation—may help reveal whether the center of our galaxy is rich in dark matter. theconversation.com/upcoming-tel...

Upcoming telescopes could shed light on dark matter – astronomers are looking for these ‘fingerprints’ of the elusive substance

Scientists study small galaxies to look for hints of dark matter in the universe.

John Tomsick explains how COSI will search the skies for gamma rays in hopes of learning more about black holes and neutron stars.

There's a lot of antimatter at the center of our galaxy. Where's it coming from? John Tomsick, PI of COSI, aims to find out.

What's a Compton telescope? John Tomsick, PI of COSI, explains.
