Year in Science: Neutron star smashup leads the list

For the second year in a row, the journal Science is hailing a discovery sparked by the Laser Interferometer Gravitational-Wave Observatory as the Breakthrough of the Year. Last year, the breakthrough was LIGO’s first-ever detection of a gravitational-wave burst thrown off by the merger of … Continue reading

Scientists spot a smallish black hole smashup

It took months to figure it out, but the scientists in charge of the Laser Interferometer Gravitational-wave Observatory, or LIGO, have confirmed their observations of the most lightweight black hole merger yet. The latest detection provides further confirmation of Einstein’s general … Continue reading

Hubbub hints at smash-up of neutron stars

Another big announcement about gravitational waves is coming up, and this time the hints point to  observations in electromagnetic wavelengths as well — emissions of light that may have come from a collision of neutron stars, or a supernova. That would … Continue reading

Gravitational wave hunters win Nobel for physics

This year’s Nobel Prize for physics is going, unsurprisingly, to three people who represent the hundreds of researchers behind the first direct detection of gravitational waves at the Laser Interferometer Gravitational-wave Observatory, or LIGO. Some of those researchers work at the LIGO … Continue reading

Third black hole crash expands LIGO frontier

The Laser Interferometer Gravitational-wave Observatory has detected its third confirmed black hole merger, and this one’s a doozy: LIGO’s latest discovery is about 3 billion light-years away, which is more than twice as far away as the first two finds. The … Continue reading
