On a frigid orbit beyond Neptune, some of the solar system’s smallest worlds project a strange silhouette. Two rounded lobes, pressed together with a narrow “neck,” like a snowman that never melted.

Objects in the solar system with weird orbits have been linked to a close encounter with another star during our stellar system's infancy. Findings of a new study suggest stellar flybys can indeed ...

A bound pair of icy comets similar to the dirty snowballs circling outside the orbit of Neptune has been found lurking in the shadow of Jupiter. Astronomers at the University of California, Berkeley, ...

Since the third Gaia data release in 2022, wide binary stars with separation greater than several thousand astronomical units have been intensely investigated across the world, to probe the nature of ...

Berkeley — A bound pair of icy comets similar to the dirty snowballs circling outside the orbit of Neptune has been found lurking in the shadow of Jupiter. Astronomers at the University of California, ...

An international team of astronomers has shown that the two stars in the binary HM Cancri definitely revolve around each other in a mere 5.4 minutes. This makes HM Cancri the binary star with by far ...

Astronomers have discovered a bizarre star system containing two ultra-cool dwarf stars that are so close together they orbit each other in less than a day. Oh, and they’re invisible to the human eye.

An international research team announces the discovery of a new exoplanet orbiting a binary star system. Named HD 143811 b, ...

This unusual system 'shouldn't exist,' says one astronomer, who notes the orbit is as long as his daily commute. By Briley Lewis Published Aug 8, 2023 6:00 AM EDT Get the Popular Science daily ...

Using an old-style observing technique, astronomers have come to a very interesting conclusion: About half of all exoplanets in the galaxy are in binary star systems. That’s astonishingly cool. Mind ...

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 ...
