SUNSET: 
Astronomers Witness X-ray Burst from Newborn Neutron Star
Astronomers have discovered a newborn neutron star in a rare pairing with an old red giant companion.
Neutron Stars Discovered on Collision Course
Got any plans in 46 million years? If not, you should keep an eye out for PSR J1946+2052 around that time — this upcoming merger of two neutron stars promises to be an exciting show!
Nights of the Living Dead — What Stars Leave Behind
Stars leave interesting messes after they die: diamond-studded puffballs, neutron stars, and black holes. We explore an example of each in June's night skies.
Does This Neutron Star Confirm an 80-Year-Old Quantum Prediction?
Scientists have been looking for decades to confirm a weird quantum effect first predicted in 1936. Have they finally found hard evidence for it?
LIGO Detects Second Black Hole Collision
The gravitational wave observatory has detected a second event, heralding a new era in astrophysics. The day after Christmas last year, the cosmos quietly gifted scientists with gravitational waves — ripples in the fabric of spacetime – produced in a collision between two stellar-mass black holes. It’s the second event…
There Be Monsters Here! How to Find the Biggest Star
Antares and Betelgeuse may be colossal stars, but we take it to the next level of stellar monstrosity with a visit to UY Scuti, a star that makes our Sun seem no bigger than a pinpoint.
Witnessing Light Echoes from a Neutron Star
X-ray echoes from binary star system Circinus X-1 are helping astronomers measure its distance from Earth.
Taming the "Zoo" of Neutron Stars
These stellar corpses have many faces, from pulsars to magnetars. New models provide evidence for unifying these disparate objects under one theory.
Neutron Star Gobbles Gas, Burps X-rays
Astronomers have observed a neutron star flaring to 10,000 times its original brightness.
A Neutron Star's Hard Core
Astronomers have found some pulsars that appear unusually massive, calling into question our understanding of neutron-star interiors.
Measuring Neutron Stars Exactly
Astronomers can measure a neutron star's diameter by effects of gas skimming around its surface at 40% of light speed.
