Do you know which planet could float in a giant bathtub? Discover the science behind its low density, its hundreds of moons, and its famous rings.

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 ...

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 ...

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 ...

Many of the exoplanets we’ve discovered look at least vaguely like something we’re familiar with. Exoplanets have been described as super-Earths, mini-Neptunes, hot Jupiters, and so on. But not ...
