Jupiter's largest moons don't go completely dark when the giant planet blocks their sunlight, astronomers have found.

The discovery could reveal more about Jupiter's mysterious upper atmosphere, which the researchers suspect is responsible for keeping the moons lit when they are not directly illuminated by the sun. This research could also help scientists better understand the atmospheres of alien planets, study team members said.

Via NASA:

wo hours before closest approach to Neptune in 1989, the Voyager 2 robot spacecraft snapped this picture. Clearly visible for the first time were long light-colored cirrus-type clouds floating high in Neptune's atmosphere. Shadows of these clouds can even be seen on lower cloud decks. Most of Neptune's atmosphere is made of hydrogen and helium, which is invisible.Neptune's blue color therefore comes from smaller amounts of atmospheric methane, which preferentially absorbs red light. Neptune has the fastest winds in the Solar System, with gusts reaching 2000 kilometers per hour. Speculation holds that diamonds may be created in the dense hot conditions that exist under the cloud tops of Uranus and Neptune. Twenty-six years later,NASA's New Horizons is poised to be the first spacecraft to zoom past Pluto this July.

A black hole is essentially a ludicrous amount of mass concentrated in an incredibly small space. They're called singularities because gravity becomes measurably infinite at a single point. They suck in everything around them like cosmic vacuum cleaners, and past the event horizon of a black hole nothing can escape, not even light.
