Charting the Cosmic Shoreline: Which Planets Have Atmospheres?
New observations of the M-dwarf exoplanet Gliese 486b help astronomers map the location of the cosmic shoreline, which separates planets with atmospheres from those without.
Researchers show how preferential accretion in a merging pair of supermassive black holes can explain the unexpectedly large amplitude of the gravitational wave background.
Astrobites reports on simulations that explore whether a baby neutron star repeatedly diving into the envelope of its inflated companion star could be the cause of bumpy supernova light curves.
Researchers have investigated how solar flares might signal that they’re about to occur and whether they’ll be accompanied by an explosion of plasma.
Astrobites reports on efforts to understand how the variability of certain variable stars changes over time.
What can ultraviolet observations from Hubble tell us about the identity of Betelgeuse’s likely companion star?
JWST discovered a distant galaxy with too much nitrogen, which has led to evidence of the universe’s first stars.
Black Holes with a Shared Background
New research suggests that triplet stars might be able to evolve into every observable type of stellar-mass black hole system.
