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

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

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.

A star known as S0-2 (the blue and green object in this artist’s rendering) made its closest approach to the supermassive black hole at the center of the Milky Way in 2018. (Nicole Fuller / National ...

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 ...

LIGO's GW250114 signal tests Einstein's relativity, revealing black hole properties and confirming key theorems in ...

Since 1915 when Albert Einstein published his theory of general relativity, scientists have worked on testing its limits, and with the results of this 16-year test, it still holds up. Professor ...

A prediction made by Albert Einstein in his theory of general relativity has come true as astrophysicists have detected light coming from behind a black hole. A team of scientists made the analysis ...

An international team of scientists have completed the first successful test of Albert Einstein's famous theory of general relativity (GR) near a supermassive black hole, according to a study ...
