On September 14, 2015, a signal arrived on Earth, carrying information about a pair of remote black holes that had spiraled together and merged. The signal had traveled about 1.3 billion years to ...

Ten years after the historic discovery of gravitational waves, and having spotted hundreds more of these space-time swells since then, physicists say they are only just getting started. On 14 ...

Installation of in-vacuum equipment as a part of the squeezed-light upgrade before Advanced LIGO’s third observing run. LIGO team members install in-vacuum equipment that is part of the squeezed-light ...

Ten years after LIGO’s historical detection of gravitational waves, the project is cracking black hole mysteries at an astounding pace. Reading time 4 minutes LIGO’s discovery of gravitational ...

A signal lasting less than a second traveled about 1.3 billion light years before it reached an observatory deep in the piney woods of Livingston 10 years ago. The brief signal — caused by a pair of ...

The Laser Interferometer Gravitational-Wave Observatory, or LIGO, has already won its researchers a Nobel Prize — and now artificial intelligence is poised to take LIGO’s search for cosmic collisions ...

Scientists believe if the Trump administration's proposed budget is approved, a Louisiana space observatory could be on the chopping block and see its scientific mission crippled. The Trump ...

Ten years ago, astronomers made an epic discovery with the Laser Interferometer Gravitational-Wave Observatory. Cosmology hasn’t been the same since, and it might not stay that way much longer. Out ...

Long ago, in a galaxy far away, two black holes danced around each other, drawing ever closer until they ended in a cosmic collision that sent ripples through the fabric of spacetime. These ...

Physicist who won a Nobel Prize for LIGO Hanford observatory in Eastern WA died. LIGO confirmed Einstein’s theory of relativity by detecting gravitational waves in 2015. Twin LIGO sites in WA and LA ...
