SUNSET: 
What Kinds of Black Hole Partners Merge?
New research on black hole mergers reveals that the black hole pairs tend to have similar masses — suggesting that they start out as massive stellar pairs.
Mismatched Black Holes Merge
For the first time, the LIGO and Virgo gravitational-wave detectors have "heard" gravitational waves from an unequal pair of black holes.
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.
Gravitational Waves from Second Neutron-star Collision Observed
Scientists with the Laser Interferometer Gravitational-wave Observatory (LIGO) and Virgo collaborations have announced the detection of a second pair of neutron stars that went bump in the night.
More Black Hole Mergers Found in LIGO Data
Analysis by an independent team has ferreted out seven candidates for gravitational-wave events from merging black holes.
Listen Up: Get Gravitational-wave Alerts
The Laser Interferometer Gravitational-wave Observatory (LIGO) will soon begin a new round of observations. Now you can find out about the discoveries as they happen.
What LIGO Teaches Us About Black Holes
The rising count of gravitational-wave events is giving us a new look at a once-invisible population of black holes.
Gravitational-Wave Observatories Bag Four Black-Hole Collisions
A re-analysis of data from LIGO and Virgo brings the number of gravitational-wave detections to 11, including the most distant and most powerful black-hole merger yet discovered.
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.
Astronomers Catch Gravitational Waves from Colliding Neutron Stars
Spacetime ripples from the neutron star smash-up usher in the age of multi-messenger astronomy.
Fourth Gravitational Wave Event Detected
Teaming up with LIGO, Europe’s Virgo detector has bagged its first gravitational waves. The three-observatory detection enabled scientists to better pinpoint the merging black holes’ location.
Goodbye, LISA Pathfinder
The European Space Agency switched off its groundbreaking LISA Pathfinder mission this week.
LIGO Detects Third Black Hole Merger
Scientists with the gravitational-wave observatory announce another discovery, this time of a black hole merger twice as far away as previous detections.
