A data-driven approach identifies stars with interesting infrared emission without relying on computationally expensive modeling.
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.
Astrobites reports on how X-rays influenced the formation of the first massive black holes in the universe.
The Sun Left Home in a Hurry
By studying the orbits of rare outer solar system objects, astronomers have estimated how long it took for the Sun to leave its birth cluster.
