Glad to see this story covered by the press. I've heard from colleagues that Goddard labs are being moved/closed during the government shutdown while employees are unable to receive notification/e-mail/warnings. There's fear that they'll return after the shutdown & labs will be gone. 🔭
#nasa is shuttering the Goddard #space #flight center in a move that may not be entirely legal, according to critics. For months, our #staff #writer @joshdinner.bsky.social interviewed NASA #employees, read #senate reports and more to give you the deepest dive yet.

Paper day! We found dusty stars in the very metal-poor Sextans A galaxy with JWST, including one that appears to be producing only metallic iron dust instead of the expected silicates. It suggests that iron dust might be common at low metallicity (and in the early Universe). arxiv.org/abs/2507.16766
