Astronomers Create Cloud Map of Jupiter-Like Exoplanet

Astronomers have created the first map of the clouds on a planet outside our Solar System.

The planet in question is Kepler-7b, a large gaseous world like Jupiter, roughly 1,000 light-years away.

The researchers used data from Nasa’s Spitzer and Kepler space telescopes to study the exoplanet, which orbits close to its parent star.

Their results suggest the hot giant is marked by high clouds in the west and clear skies in the east.

Astronomers have previously been able to make temperature maps of planets orbiting other stars, but this is the first look at cloud structures on a distant world. Kepler-7b is something of an oddity – bigger than Jupiter, but lower in mass – with a density about the same as polystyrene. Learn more here, here or here.
