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 ...

A new study led by UNLV scientists sheds light on how planets, including Earth, formed in our galaxy—and why the life and ...

An exoplanet is a planet from a different star system. Most known exoplanets orbit stars within the Milky Way, but with the help of powerful space telescopes, scientists have discovered exoplanets far ...

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. The Kepler-51 system, ...

Fifth-graders making styrofoam solar system models may have the right idea. Researchers at Lehigh University have discovered a new planet orbiting a star 320 light years from Earth that has the ...

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 ...

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 ...

Astronomers have found planets that are twice as wide as Jupiter and more than 10 times as heavy, but there's a limit to how big planets can get. When you purchase through links on our site, we may ...

Researchers have applied physics theory and calculations to predict the presence of two new phenomena -- interspecies radiative transition (IRT) and the breakdown of the dipole selection rule -- in ...
