Old Telescope, New Tricks: Chasing Gravitational Waves Across the Sky
How can we track down colliding neutron stars as quickly as possible? New research shows that the nearly 20-year-old Swift Observatory might be our best bet.
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.
Astrobites reports on the discovery of the faintest galaxy in the Andromeda system, Pegasus VII.
Recent research shows how fractal properties can help distinguish between grand-design and flocculent spiral galaxies.
When supernovae explode, they send a fast-moving shock wave into the interstellar medium, changing the local landscape significantly. A recent publication hones in on one supernova remnant to determine how fast it’s expanding and where it may have come from.
