Rubies, Sapphires rain on Jupiter-like planet

A team lead by David Armstrong discovered that the planet-like Jupiter clouds appear to be made from corundum

Scientists have been using the Kepler telescope to observe the HAT-P-7b, an extrasolar planet discovered in 2008, after it was found twinkling in an unusual way four years ago.

Now a team lead by David Armstrong discovered that the planet-like Jupiter clouds appear to be made from corundum—the same mineral that produces rubies and sapphires.

“HAT-P-7b is a tidally locked planet, with the same side always facing its star,” Armstrong stated in a press release. “We expect clouds to form on the cold night side of the planet, but they would evaporate quickly on the hot dayside.”

The team detected this by observing the light being reflected from the planet’s atmosphere, and noticing the changes in the light over time.
