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.

In the cold, dark outskirts of planetary systems far beyond the reach of the known planets, mysterious gas giants and planetary masses silently orbit their stars—sometimes thousands of astronomical ...

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 ...

In early 2016, two planetary scientists declared that a ghost planet is hiding in the depths of the solar system, well beyond the orbit of Pluto. Their claim, which they made based on the curious ...

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 ...

Add Yahoo as a preferred source to see more of our stories on Google. Astronomers have detected an exoplanet with a highly oblong orbit that experiences wild temperature swings — and it may be ...

Astronomers have detected over 5,800 confirmed exoplanets. One extreme class is ultra-hot Jupiters, of particular interest because they can provide a unique window into planetary atmospheric dynamics.

What they found were two Exo-Jupiter planets called PDS 70b and PDS 70c. This isn't too unusual. However, in the Trojan point next to PDS 70b there was a cloud of debris with about twice the mass of ...

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 ...
