Pulling Back the Curtain on DART Ejecta
After the DART spacecraft smashed into Dimorphos, a cloud of ejecta expanded outward. A recent study builds a 3D reconstruction of the ejecta and determines that it’s more complex than previous models considered.
Black Hole Baby Photos: JWST and Chandra Observe M31-2014-DS1
Did the disappearance of a star in the Andromeda Galaxy signal the creation of a black hole? New infrared and X-ray data help to discern what remained after the star disappeared.
Ursa Major III/UNIONS 1: Dwarf Galaxy or Star Cluster?
Researchers investigate whether the Milky Way’s smallest known satellite is a tiny dwarf galaxy or a star cluster.
Monthly Roundup: Updates on Three Notable Transients
What’s new with AT 2024wpp, GRB 250702B, and GW231123? Get updates on these three exceptional astrophysical transients in today’s Monthly Roundup.
Do Black Hole Flares Generate Neutrinos?
Researchers search for a connection between short-lived black hole accretion events and neutrinos — elusive, neutral, nearly massless particles.
Satellite Surplus Around Dwarf Galaxy DDO 161
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.
Mapping a Molecular Building Block in a Pre-Stellar Core
Astronomers search for a simple organic molecule in Lynds 1544, a cold, dense clump of gas that will one day become a star.
JWST Spies a Potential Microlensed Massive Binary Star System
A chance alignment between galaxies allows astronomers to study a single star system as it was when the universe was just 6 billion years old.
