It rains sunscreen on this 'hot Jupiter' exoplanet
Anyone who can conjure up a way to collect resources from Kepler-13Ab in the far future could become a sunscreen magnate. On the heavenly body, one of the hottest Jupiter-sized exoplanets the mission has ever discovered, titanium oxide falls from the skies. The planet is so close to its host star that, like our moon, one side permanently faces Kepler-13A while the other is permanently in darkness. This titanium oxide "snowfall" takes place on the dark side, because winds tend to carry it to colder areas.
Hot Jupiter planets can speed up their stars' rotation
Hot Jupiter exoplanets are the farthest thing from habitable, but that doesn't mean they're boring. Scientists from Princeton University and elsewhere have discovered one that is so large and close to a star that it actually changes its rotational speed. Called HATS-18 after the main telescope (HATSouth) used to discover it, the planetary system is about 2,100 light-years away. However, it's ridiculously near its star (closer than Mercury is to our sun) and huge, at 1.34 times the size of Jupiter, so it completes an orbit in less than an Earth day.
