NASA has completed the construction of #NASARoman! Last month, technicians joined the inner and outer portions of the observatory in Maryland. After final testing, Roman will move to the launch site at the Kennedy Space Center for launch preparations in summer 2026: https://go.nasa.gov/48EqnE8 🔭 🧪

In Michelle's second paper, she updates us all on the offensively faint Ursa Major III/UNIONS 1 stellar association. Is it a galaxy wtih dark matter or a star cluster? This new paper searches for signs of dark matter and/or binary stars to answer this question! arxiv.org/abs/2510.02431 🔭 ☄️

So exciting!!

Looking for a last minute holiday gift? Mia and the Martians is a new children’s book by myself and @tanyaofmars.bsky.social all about a little girl and her cat, Nebula, who go to Mars for her science fair. They meet the rovers and learn science and emotional lessons from each one amzn.to/4fvtBuQ

Aaand our next Aeos paper is out as well!! Jennifer Mead leads the paper, finding feedback blows out all metals from early halos until they reach a mass of about 10^7 Msun. Read it here: arxiv.org/abs/2411.14209

🔭 Paper announcement! With @alexji.bsky.social, @wcerny.bsky.social, and a host of others, we analyze some of the first spectroscopy of stars in compact (r < 10 pc), ultra-faint Milky Way satellites in arxiv.org/abs/2410.08276. Our two target systems are highlighted here:

Our paper on the Barbenheimer Star is now published in ApJL! iopscience.iop.org/article/10.3... We at @sdssurveys.bsky.social find evidence for an ancient explosion of an unusually massive star that should have collapsed to a black hole. Thread and 🔭 Image: UChicago/SDSS-V/Melissa Weiss

Okay, this is pretty cool -- Vera Rubin will be on 2025 American quarters!! 🔭 www.usmint.gov/news/press-r...

I'm a day late, but I wanted to advertise the latest paper from the DES and DELVE collaborations, led by Mitch McNanna! The paper's results include the discovery of a *very* diffuse (resolved) dwarf galaxy candidate near the LMC-mass host NGC 55 (D ~ 2 Mpc). Read it here: arxiv.org/abs/2309.04467
