A giant planet in the HR 8799 system orbits six times faster than its neighbor, reigniting the mystery surrounding its origin ...

Astronomers have long been puzzled by a cosmic mystery: planets orbiting two stars—like Star Wars’ Tatooine—are surprisingly rare, even though they should be common. New research suggests the culprit ...

Astronomers at The University of New Mexico have published new research confirming three bodies orbiting the dynamic ...

Astronomers have recently uncovered a remarkable planetary system around the faint orange star WASP-132, featuring two exoplanets that couldn’t be more different. One is a rocky world that completes ...

Planets are born from the rotating disk of gas and dust that surrounds a star in its youth. While it is commonly accepted ...

Astronomers have captured a rare and remarkably close view of a giant planet circling a pair of tightly bound suns, offering one of the clearest real-world echoes yet of the fictional world Tatooine.

Surprised astronomers just discovered a world that blurs the line between planet and stellar remnant, hiding in a system known as a “black widow.” “This was an absolute surprise,” said study co-author ...

Earth’s history has been punctuated by at least five major ice ages. Some of these frigid periods of prolonged global cooling saw much of our planet locked in ice and snow for 100 million years. It ...

A team of scientists has found a new planet which orbits the wrong way around its host star. The planet, named WASP-17, and orbiting a star 1000 light years away, was found by the UK’s WASP project in ...

An artist's impression of a planetary system with four planets, around a small red star, called LHS1903 with a large reddish-brown rocky planet with craters is visible in the foreground and three ...

In theory, it could happen – one of the very first solutions to the three-body problem was this scenario. But it is very unlikely to be stable over time. You need the stars to have near equal mass and ...
