SUNSET: 
How to Warn of Imminent Neutron Star Collisions
What if gravitational-wave observatories could send out alerts right after — or even before — receiving signals of neutron star collisions?
Neutron Star Found in Supernova 1987A
After decades of searching, astronomers have finally found the collapsed core of the nearest supernova recorded in recent history.
Astronomers Discover a Newborn Magnetar and a New Cosmic Beat
This week, astronomers announce a newborn magnetar and a fast radio burst that's bursting to a beat.
Milky Way Magnetar Makes Fast Radio Burst
Fast radio bursts are mysterious — and powerful — flashes of radio waves. Now, we've found one of these flashes coming from a magnetar in our own galaxy.
Gravitational Waves Put Ruler to Neutron Stars
Scientists have combined observations of gravitational waves from a neutron star collision with nuclear theory to shed light on the size and nature of neutron stars.
Two Explosions with Similar Quirks
High-energy radiation released during the merger of two neutron stars last year has left astronomers puzzled. Could a burst of gamma rays from 2015 help us to piece together a coherent picture of both explosions?
Low-key supernova marks possible birth of neutron star duo
A massive star lost most of its mass before exploding and creating a neutron star — and a second nearby neutron star might have been the thief.
Seen at Last: A Superfast Jet Streams Away from Neutron-star Smashup
A new finding suggests that LIGO’s neutron-star merger was a typical gamma-ray burst after all.
Astronomers Discover Lonely Neutron Star with a Curious Past
New observations have helped astronomers identify the source of a 2,000-year-old supernova explosion. But this blast, and the neutron star that created it, seem to have a curious history that defies explanation.
60-Second Astro News: Imaging Black Hole Jets and Distant Stars
Astronomy news this week: Hubble images the most distant star, radio telescopes combine forces to probe black hole jet, and neutron star hotspots explained.
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…
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.
