In 2010, which is about three millennia ago on the Internet, NASA's Cassini Probe found perhaps the most important and relevant scientific discovery in the history of humanity: The heat signature of one of Saturn's moons, Mimas, looked just like Pac-Man. Today, we can all pay attention to what is clearly the most important things that will be said today, which is that another moon of Saturn, Tethys, has a similar heat signature. There's no word yet on whether this moon is a Ms. Pac-Man moon or not, but obviously we'll stay with this one all night if we have to.
The Cassini probe has been hanging around Saturn since 2004, and has given scientists an unprecedented view of the ringed planet and its moons. One of the more interesting of Saturn's natural satellites is Enceladus, which is known to not only have an icy crust, but periodically shoots geysers of water vapor, ice, and tantalizingly organic compounds. Cassini has sampled this spray before, and did again three days ago. While the analysis of the spray is probably some time away, we can enjoy these spectacular photos of Enceladus and the moon Tethys. See them, after the break.
