SUNSET: 
Did Astronomers See a Star Explode Twice?
Astronomers are trying to determine if they've witnessed a complex stellar explosion or a relatively ordinary supernova.
Priceless Flares: Magnetars Can Make Gold and Platinum
An almost forgotten observation made 20 years ago provides evidence that magnetars create some of the heaviest nuclei in the universe.
Cracking Crusts Might Set Neutron Star Speed Limit
New research explores how the cracking of a neutron star’s crust might determine how fast these extreme stellar remnants can spin.
Neutron Stars Might Be Squishy Inside
New data on the brightest pulsar observed with a telescope on the International Space Station suggests neutron star interiors are "squishy."
Astronomers Find 21 “Dark” Neutron Stars Orbiting Sun-like Stars
New analysis has revealed 21 Sun-like stars in mutual orbit around dark objects of neutron star–like masses — rare systems that have escaped destruction by supernova.
Three Neutron Stars Reveal Inside Secrets
Astronomers surveyed dozens of neutron stars, homing in on three that challenge most ideas about what these exotic objects are made of.
Gotcha: Firm Evidence for a Neutron Star in Supernova 1987A
After decades of debate, James Webb Space Telescope observations provide firm evidence of a neutron star inside the 1987A supernova remnant.
Lightest Neutron Star Ever? Maybe, Maybe Not
A team of astronomers claims to have measured the lightest neutron star, but others say extraordinary claims require extraordinary evidence.
Stellar Remnant at the Core of Mysterious Flash Dubbed "The Cow"
Astronomers have identified the origin of a mysterious flash that occurred three years ago.
What’s Inside Neutron Stars?
Size measurements of two neutron stars have narrowed down what kinds of exotic matter might exist in their extremely dense cores.
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 evidence for a collapsed core at the center 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.
