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.

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

Astronomers have discovered how "forever young" stars stay blue and bright despite being almost as old as the universe.

Cosmic radio pulses repeating every few minutes or hours, known as long-period transients, have puzzled astronomers since ...

An international collaboration of astrophysicists that includes researchers from Yale has created and tested a detection system that uses gravitational waves to map out the locations of merging black ...

From degeneracy to galactic archaeology, white dwarfs are helping scientists make sense of some of the universe's burning ...

Long-term observations reveal that at least some fast radio bursts are linked to magnetars orbiting companion stars.

"We studied the last several orbits before the merger, when the entwined magnetic fields undergo rapid and dramatic changes, ...

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.

NGC 7331, the sight of supernova SN2025rbs, imaged by George Gheirchi (US).

Sherlock Holmes might as well have said, “It’s binary, my dear Watson,” instead of “It’s elementary.” We are immersed in a world of dichotomies comprising binary categories, such as true or false, ...

A hybrid computer uses rotating mechanical beams for memory and electrical contacts for logic, performing reprogrammable computation through physical motion in environments where conventional ...
