Scorching hot exoplanet 'snows' sunscreen

Astronomers have observed an extrasolar planet with some of the weirdest weather conditions ever seen.
Six times more massive than Jupiter and situated at a distance of 1,730 light years from the Earth, Kepler-13Ab, with often sees dayside surface temperatures of up to 5,000 degrees Fahrenheit, is one of the hottest extrasolar planets ever discovered .

Situated extremely close to its parent star and with an orbital period of 1.8 Earth days, this distant world is tidally locked so that one side of the planet is always facing its star.

Now astronomers believe that strong winds may also carry titanium dioxide - one of the active ingredients in sunscreen - around to the planet's cooler side where it condenses in to clouds.
The peculiar 'snow' then falls in to the lower atmosphere where it stays due to the planet's gravity.

"These observations of Kepler-13Ab are telling us how condensates and clouds form in the atmospheres of very hot Jupiters, and how gravity will affect the composition of an atmosphere," said study lead author Thomas Beatty from Pennsylvania State University.

"When looking at these planets, you need to know not only how hot they are, but also what their gravity is like."

Sounds like we found Mercury's BIG brother.  Titanium dioxide is also used in paints for opacity and brightness.  It's in many other types of coatings and is used in paper for opacity as in paints.
