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

UCLA astrophysicists have now measured the shape of the orbits of exoplanets—from the size of Jupiter down to the size of Mars—and shown that small planets have nearly circular orbits, while giant ...

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 ...

Planet hunters have grown used to strange worlds, but a handful of discoveries now point to something even more radical: giant planets that loop around their stars on orbits so skewed they almost defy ...

Webb finds a massive planet, 29 Cygni b, orbiting a nearby star, offering new clues about how even the largest planets grow ...

While our Sun prefers to go solo, many other stars are parts of binary systems, with a pair of stars gravitationally bound to each other. In some cases, the stars are far enough apart that planets can ...

The strangest part of the TOI-201 system is not that it holds three very different worlds. It is that astronomers can ...

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

This illustration shows an exoplanet orbiting around two brown dwarfs –– objects bigger than gas-giant planets but too small to be proper stars. ESO/M. Kornmesser Astronomers have discovered a ...

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 ...

Is there a massive undiscovered planet on the outer reaches of the solar system? The idea has been around since before the discovery of Pluto in the 1930s. Labeled as planet X, prominent astronomers ...
