For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational ...

Astronomers have found thousands of exoplanets around single stars, but few around binary stars—even though both types of ...

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 ...

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.

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

Learn why only 14 out of over 6,000 exoplanets orbit two stars, and how Einstein’s general theory of relativity may be to blame.

Published January 7 in the journal Nature, one paper tackled the age-old problem of nature’s construction with a bit of a twist: it suggests that living networks, like our brain, may use some of the ...

Time is a straightforward concept - or is it? The passing of minutes and years isn't as easy to explain as many assume.

Recent James Webb Space Telescope data confirms a decade-old theory that the universe's earliest supermassive black holes ...

Their tests spanned the entire life cycle of the collision: inspiral, merger, and ringdown. Remarkably, the constraints were ...
