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.

In 1905, Albert Einstein revolutionized physics by demonstrating that time is not absolute but relative to the observer's ...

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 ...

Nearly 40 years after Stephen Hawking's A Brief History of Time, Sarah Alam Malik's epic exploration of the cosmos reflects a ...

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