LIGO detects gravitational waves from neutron stars colliding

Gravitational waves from the collision of two neutron stars have been detected for the second time ever — along with another, less certain signal that a neutron star being swallowed by a black hole.

Gravitational-wave observatory LIGO set to double its detecting power

A planned US$35-million upgrade could enable LIGO to spot one black-hole merger per hour by the mid-2020s.

LIGO and Virgo announce four new gravitational-wave detections

The LIGO and Virgo collaborations have now confidently detected gravitational waves from a total of 10 stellar-mass binary black hole mergers and one merger of neutron stars.

Colliding neutron stars likely formed low-mass black hole

The merger of two neutron stars generated gravitational waves and high-energy gamma radiation and detected last August likely produced a record low-mass black hole.

LIGO’s gravitational wave detection takes home a Nobel

The gravitational wave events recorded in LIGO are actually the first direct indication of the existence of black holes. Three scientists from US wins 2017 Nobel prize in physics.

LIGO just detected gravitational waves for the THIRD time

The Laser Interferometer Gravitational-wave Observatory (LIGO) has done it again, detecting gravitational waves rippling away from a cosmic collision between a pair of black holes.

LIGO black hole echoes hint at general-relativity breakdown

Gravitational-wave data show tentative signs of firewalls or other exotic physics.

Gravitational Waves May Permanently Alter Spacetime

Finding evidence of gravitational-wave memory could help solve the black hole information paradox.

The universe is crowded with black holes, astronomers predict

Astronomers have presented one of the most complete models of matter in the universe and predict hundreds of massive black hole mergers each year observable with the second generation of gravitational wave detectors.

For second time, LIGO detects gravitational waves

Signal was produced by two black holes colliding 1.4 billion light years away.

Dark Matter May Be Made Up of Black Holes

Now, some astronomers are beginning to think that dark matter is actually made up of ancient black holes formed during the first second of our universe's existence.

Anti-gravity dream may take off

The genius of Albert Einstein lead us to gravitational waves - maybe someday another genius will work out how to make them, says Dr Karl.

LIGO Chirp - The Sound of Two Black Holes Colliding

Gravitational waves sent out from a pair of colliding black holes have been converted to sound waves, as heard in this animation.
