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.
A planned US$35-million upgrade could enable LIGO to spot one black-hole merger per hour by the mid-2020s.
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.
An international team of scientists have detected gravitational waves from the biggest known black-hole collision that formed a new black hole about 80 times larger than the Sun.
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.
For the first time, gravitational waves have been detected coming from the violent collision of two neutron star potentially solving the mystery of where heavy elements like gold come from as well as producing a visible afterglow detected by over 70 telescopes around the world.
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.
Last year’s gravitational wave discovery may have felt like the end of an era. The discovery, instead, spawned an entirely new field of astronomy, and the results are finally starting to trickle in.
A new study by a team from US indicates that black hole mergers could be very common, which has implications for the study of black holes and gravitational waves.
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.
Hidden dimensions could cause ripples through reality by modifying gravitational waves – and spotting such signatures of extra dimensions could help solve some of the biggest mysteries of the universe.
Scientists have proposed a new theory that combines some of the most mysterious phenomena in the Universe - black holes, gravitational waves, and axions - to solve one of the most confounding problems in modern physics.
The telescope, located 5,250 meters above sea level, will detect and gather precise data on primordial gravitational waves in the Northern Hemisphere. It is expected to be operational by 2021.
Gravitational-wave data show tentative signs of firewalls or other exotic physics.
Finding evidence of gravitational-wave memory could help solve the black hole information paradox.
