A planet circling at a sharp 90-degree angle to the orbits of its two host stars has now been confirmed. This discovery challenges long-standing ideas about how planets form and orbit in the cosmos.

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 ...

Up until now, exoplanet surveys have mostly focused on nearby, bright stars that are sun-like or are red dwarfs, which are known to frequently host planets. While astronomers have discovered thousands ...

Astronomers have found a planet that orbits at an angle of 90 degrees around a rare pair of peculiar stars. This is the first time we have strong evidence for one of these 'polar planets' orbiting a ...
