More than 1,700 light-years from Earth lies a sizzling hot planet orbiting another star. While temperatures can soar to 2,700 C, the planet also produces some unique precipitation in the form of "sunscreen" snow. They found the planet snows titanium oxide, the active ingredient in some sunscreens. On those planets, the titanium oxide absorbs light and reradiates it, which in turn makes the atmosphere warmer at higher altitudes. In the case of Kepler-13Ab, the titanium oxide is removed from the day side which produces the opposite effect.
