JWST found a carbon-atmosphere planet orbiting a pulsar, challenging current models of how planets form. Scientific progress ...

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 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 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 ...

ITS STAR. THIS ANIMATION DEPICTS THE FINAL MOMENTS OF A GIANT GAS PLANET AS IT IS GOBBLED UP BY A STAR. IT’S SOMETHING SCIENTISTS KNEW HAPPENED BUT HAD NEVER WITNESSED UNTIL NOW. PROBABLY A GIANT ...

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 ...

The International Astronomical Union defines a planet as a celestial body that orbits the sun, is massive enough that gravity has forced it into a spherical shape, and has cleared away other objects ...
