Reading a Chapter of Galactic History from a Single Star
The star SOS1 is not like its neighbors — what do high-precision chemical abundances tell us about where this star might have come from?
Astrobites reports on how astronomers are using JWST to figure out if star clusters are really as old as they seem.
Researchers investigate whether the Milky Way’s smallest known satellite is a tiny dwarf galaxy or a star cluster.
What’s new with AT 2024wpp, GRB 250702B, and GW231123? Get updates on these three exceptional astrophysical transients in today’s Monthly Roundup.
Researchers search for a connection between short-lived black hole accretion events and neutrinos — elusive, neutral, nearly massless particles.
Astrobites reports on simulations that might help astronomers identify double-detonation supernovae early in their evolution.
How do giant low-surface-brightness galaxies form? New research investigates two galactic specimens to search for clues.
A satellite-rich dwarf galaxy poses a potential problem for current cosmological models.
Investigating a Polluted White Dwarf
JWST spectra illuminate the composition of the debris disk around GD 362, one of the most polluted white dwarfs known.
