(NASA/JPL via Wired Science) Moon Shadow Over Neptune
In 2009, 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. His composite view of Despina and its shadow is composed of four archival frames taken on 24 August 1989, separated by nine minutes. Despina itself has been artificially brightened to make it easier to see.
