LIGO and Virgo detect neutron star smash-ups

On April 25, 2019, the National Science Foundation's Laser Interferometer Gravitational-Wave Observatory (LIGO) and the European-based Virgo detector registered gravitational waves from what appears likely to be a crash between ...

Barfing neutron stars reveal their inner guts

We don't really understand neutron stars. Oh, we know that they are – they're the leftover remnants of some of the most massive stars in the universe – but revealing their inner workings is a little bit tricky, because ...

DIY gravitational waves with 'BlackHoles@Home'

Researchers hoping to better interpret data from the detection of gravitational waves generated by the collision of binary black holes are turning to the public for help.

Black holes: picturing the heart of darkness

Astronomers are poised Wednesday to unveil the first direct image of a black hole and the surrounding whirlwind of white-hot gas and plasma inexorably drawn by gravity into its ravenous maw, along with the light they generate.

It's a one-way street for sound waves in this new technology

Imagine being able to hear people whispering in the next room, while the raucous party in your own room is inaudible to the whisperers. Yale researchers have found a way to do just that—make sound flow in one direction—within ...

LIGO and Virgo resume search for ripples in space and time

The National Science Foundation's LIGO (Laser Interferometer Gravitational-Wave Observatory) is set to resume its hunt for gravitational waves—ripples in space and time—on April 1, after receiving a series of upgrades ...
