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.

The vast majority of exoplanets that have been discovered are within star systems broadly similar to our solar system: one (or sometimes two or more) stars at the center, with planets orbiting at a ...

Astronomers at the University of Arizona’s Steward Observatory, led by Kevin Wagner, have identified evidence for a potential ...

Astronomers reported Wednesday the discovery of what could be two planets sharing the same orbit around their star.They said it’s the strongest evidence yet of this bizarre cosmic pairing, long ...

In a solar system far, far away, astronomers have discovered evidence of possible "sibling" planets sharing the same orbit. The researchers detected a cloud of debris in the same orbital path as an ...
