How Much of Dark Matter Is Made Up of Tiny Black Holes?
Is dark matter actually ancient black holes the size of planets? New research places a limit on how much of the universe’s most mysterious matter could be made up of tiny black holes.
Lasting multiple hours and featuring several bursts, GRB 250702B is a rare, powerful, and unusual gamma-ray burst. What do JWST observations tell us about the host galaxy and origins of this event?
Are Water Worlds Just Made of Soot?
Astrobites reports on whether the low-density planets that keep popping up in our growing collection of exoplanets are really the water worlds that we imagine them to be.
New research suggests that ultra-long-period pulsars might begin their lives as massive stars in close binary systems.
Though less destructive than coronal mass ejections, moderate space weather events like stream interaction regions can still cause geomagnetic storms. Researchers have used machine learning to investigate the drivers behind these events.
A Black Hole Egg That Forgot to Hatch
Astrobites reports on how astronomers got a closer view of the distant and mysterious little red dots.
The CANUCS survey brought five galaxy clusters into focus, painting a portrait of galactic life in the early universe.
AAS 247: Day 4
On the final day of AAS 247, researchers described early signs of spiral galaxy structures, gravitational wave astronomy performed with pulsars, and measurements of baryon acoustic oscillations.
AAS 247: Day 3
On Day 3 of AAS 247: a record-breaking asteroid, a discussion of science policy, and a supernova that we might hear about again at AAS 367!
