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.

Gravitational Waves Shed Light on Neutron Star Interiors

The gravitational-wave detection last year of a neutron star merger has revealed details on neutron star structure, ruling out exotic quark matter in the objects’ cores.

Neutron-star Smashup Might Have Choked Its Own Jet

LIGO’s neutron-star smashup might not have been a typical short gamma-ray burst. If true, the detection points toward a new class of gamma-ray bursts — but the jury is still out.

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…

LISA Pathfinder Surpasses Expectations

First science results from ESA's LISA Pathfinder mission exceed expectations, with five times the sensitivity. This result paves the way for a future full-scale gravitational wave observatory in space.

Did Fermi Detect LIGO’s Merging Black Holes?

NASA’s Fermi Gamma-ray Space Telescope might have detected a burst from the same merging black holes that emitted the gravitational waves LIGO detected.
