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.

Stargazers can see six planets all in one evening during the second month of the year, especially Mercury, which is usually ...

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 2018, astronomers discovered a brown dwarf binary system. Brown dwarfs are stellar objects that never had enough mass to fuse hydrogen and become fully fledged stars. They are often found in ...

While there is a little wiggle room, the planets in our solar system really are orbiting on mostly the same level. Why do ...

The planets have been nicknamed Earth's seven sisters. — -- An international team of astronomers has discovered seven potentially habitable exoplanets — or planets outside our solar system — that ...

A team of astronomers observed a confused exoplanet orbiting its two parent stars in a highly unusual way. As New Scientist reports, the planet, which was first discovered in 2004, is located in a ...

In a real-life twist on Star Wars' Tatooine—a harsh desert planet with twin suns and a criminal underbelly—astronomers have found a bizarre new world that orbits two stars at a perfect right angle.

Some of the most promising places to look for extraterrestrials have remained, so far, mostly hidden from astronomers. Now a game-changing instrument called NIRPS (Near-Infrared Planet Searcher) is ...

A new "Tatooine-like" planet outside the solar system may orbit two failed stars, scientists reported Wednesday.Related video above: The dark energy pushing our universe apart may not be what it seems ...
