Astronomers have discovered a new Jupiter-sized exoplanet that possesses less than one-third of the mass of the solar system's largest planet, giving it a density similar to a marshmallow. The team ...

A Neptune-sized planet denser than steel has been discovered by an international team of astronomers, who believe its composition could be the result of a giant planetary clash. A Neptune-sized planet ...

Giant alien worlds known as hot Jupiters, with searing, close orbits to their host stars, can inflate like balloons. Now, astronomers have discovered a hot Jupiter so puffy that it is one of the least ...

Two tightly packed families of exoplanets are pushing the boundaries of what a planetary system can look like. New studies of the makeup of worlds orbiting two different stars show a wide range of ...

Astronomers at the Kitt Peak National Observatory have spotted a peculiar gas giant exoplanet some 580 light-years away with the density of a marshmallow. And as it turns out, it may be the lowest ...

Astronomers have found a Neptune-size planet outside the solar system that’s composed mainly of water—albeit in solid form. With a torrid surface temperature of 600 kelvins, the planet can’t support ...
