Earth’s turbulent atmosphere makes it hard to detect new planets from the ground. Astronomer Rebecca Jensen-Clem is working ...

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 ...

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 ...

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, ...

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 ...

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 obtained the best evidence yet that a planet orbiting a star 400 light years away from Earth is a solid, rocky world just like our own. The extrasolar planet (or exoplanet), known as ...

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 ...

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 ...
