Despina is a tiny moon of Neptune. A mere 148 kilometers across, diminutive Despina was discovered in 1989, in images from the Voyager 2 spacecraft taken during its encounter with the solar system's most distant gas giant planet. But looking through the Voyager 2 data 20 years later, amateur image processor and philosophy professor Ted Stryk discovered something no one had recognized before — images that show the shadow of Despina in transit across Neptune's blue cloud tops.

Soares and her colleagues used high-speed cameras to film a group of nine male guppies from the island of Trinidad. Their research, published online April 16 in the journal PLOS ONE, suggests wild guppies use their curious jumping ability as a way to spread the species away from an original habitat, to a new place with fewer predators. In other words, jumping likely serves a crucial evolutionary function for guppies.
