Planetary Swing: Spitzer Space Telescope Probes Extreme Climates on Hot Jupiters and Super Earths

A simulation showing the turbulent atmosphere of exoplanet HD 80606b, based on data gathered with the Spitzer space telescope. This hot Jupiter-type world has one of the most elongated orbits known for an exoplanet, one that resembles the orbits of comets in our Solar System.

Exoplanets are now being discovered by the thousands, but most are so far away that determining anything specific about their composition or atmosphere is currently very difficult. But technology keeps advancing, and scientists are now starting to […]

Astronomers Find First Evidence of Possible Volcanic Activity On a Super-Earth Exoplanet

Discovering new exoplanets has become rather routine in the last few years, but determining just what conditions exist on any of them is naturally more difficult, […]

Hot 'Super-Earths' Provide Clues to Water in Exoplanet Atmospheres

Some of the most interesting exoplanets discovered so far are the “super-Earths,” rocky worlds which are significantly larger and more massive than Earth but still smaller than […]
