[Ars] First map of clouds on an exoplanet

Of the 2,000-plus planets discovered orbiting alien stars, only one has been found to have clouds. The planet, Kepler-7b, is one of the earliest exoplanets discovered. If you were hoping the clouds could be a sign of life, you’re likely to be disappointed. Kepler-7b, like other early exoplanets, is a gas giant larger than Jupiter.

And like many exoplanets, Kepler-7b is a “Hot Jupiter,” meaning it orbits very close to its star. It’s about 44 percent the mass of Jupiter but about 1.6 times its size and orbits its host star at about 0.6 astronomical units from its star (Earth is one AU from the Sun).

The planet is unusual in a few ways. Its large size and small mass mean that it has a low density, lower than is predicted by current models of planetary interiors. It’s about as reflective to light as Jupiter, which is also not expected for a planet so close in to its star. That’s because the star is close enough that its light should strip away the clouds and leave the planet dark.

While most exoplanets have been consistent with that prediction, Kepler-7b isn’t the only exception. The researchers suggest that, in Kepler-7b’s case, the planet’s low gravity might help maintain the cloud cover by allowing material to easily float up into the upper atmosphere, creating new clouds.

Too much negativity on these forums sometimes, so today we get funky planets! Pretty cool how being a tidally locked hot Jupiter affects the clouds. I wish the image wasn't so dark.

Looks like some kind of weird eyeball to me without the iris or anything, just whites + muscles.

Read the article but I'm still little confused, is that a rendering based on information from the two telescopes or is that actual rough image touched up by scientists.

Neither. It's an artist's conception. They have not published the map they developed in that article, but it is very low resolution and not nearly as appealing as the artist representation.

Ha, good one applaud.gif I was just going to say alien farts or some crap like that

Hmm weird... this was probably already discussed when they found the planet, but isn't it weird that a gas giant would be so close to a star? I remember learning something along the lines of rocky small planets exist close to stars and gas giants tend to be a bit further away.
Sorry AMD

I guessed that is why its mass is so much less than jupiter but its size is so much larger. Like a hot air balloon, pull it from its orbit close to the star and its size would shrink greatly as it cooled
