A record-breaking gravitational wave signal let scientists "listen" to a distant black hole merger and put Einstein's gravity ...

New research suggests Einstein's general relativity explains the rarity of planets orbiting two suns. In tight binary systems ...

The big thinkers at Aperture explain relativity and how it warps the fabric of spacetime.

General relativity helps explain the lack of planets around tight binary stars by driving orbital resonances that eject or destroy close-in worlds. This process naturally creates a “desert” of ...

Astronomers have found thousands of exoplanets around single stars, but few around binary stars—even though both types of stars are equally common. Physicists can now explain the dearth.

A newly detected gravitational wave, GW250114, is giving scientists their clearest look yet at a black hole collision—and a powerful way to test Einstein’s theory of gravity. Its clarity allowed ...

Astronomers have long faced a strange contradiction: most stars are born in pairs, and ...

One such mystery, described in a recent paper in The Astrophysical Journal Letters, concerns circumbinary exoplanets—or rather, the shortage thereof—in the now 6,000+ exoplanets confirmed to date.

For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational wave signal from a binary black hole merger to date, and it gives researchers ...

The sharpest black hole collision ever detected just gave Einstein another win—and raised hopes that the next one might ...

The second reason is simple: location, location, location! The millisecond pulsar appears to be near Sagittarius A*, the ...

Cooling metal bars to near absolute zero, suspending microscopic gold beads, or searching for signs that gravity might be ...
