Gravitational Waves

Most of the universe's gold, uranium and other heavy elements are generated from rapidly whirling collapsing stars, a new study finds.

Upcoming gravitational-wave observatories both on Earth and in space could soon help solve some of the greatest mysteries in science.

Just a month into a new observing round after significant improvements, gravitational-wave detectors have already used ripples in space-time to pinpoint five collisions of cosmic proportions.

Scientists want your help studying black holes — and you can do it from your own home!

Astronomers have apparently spotted another epic neutron-star crash — and they didn't need gravitational waves to do it.

Analyzing ripples in the fabric of space and time created by pairs of dead stars may soon solve a cosmic mystery surrounding how quickly the universe is expanding — if scientists are lucky.

Four new gravitational-wave observations mean scientists can start to make broader discoveries about the world around us and the black holes that fill it.

Once again, a decades-old theory of gravity has survived a modern scientific onslaught. Einstein wins again.

The historic neutron-star crash that astronomers observed last year generated a hypermassive, supermagnetic neutron star, a recent study suggests.

The collision of black holes harboring millions or billions of times the mass of the sun are likely common throughout the universe, a new study suggests.

Cataclysmic mergers of the superdense stellar corpses known as neutron stars may be common across the cosmos, a new study suggests.

So far, gravitational waves have found no hints of extra dimensions, but there may still be some really tiny ones lurking out there.

The dramatic neutron-star merger that astronomers observed in August 2017 generated a jet of material that seemed to move four times faster than light, a new study reports.

Close encounters with medium-size black holes can reanimate dead stars, if only momentarily, a new study suggests.

The first-ever observations of merging binary stars stunned the astronomy community last year, but not quite as much as the first-ever signal from extraterrestrial life might someday stun the world.

If music really is a universal language, we can use it to make some long-sought cosmic connections. That's the idea behind Intergalactic Omniphonics, a new art project that aims to catch E.T.'s ear.
