The Violent Violet Sun
“After dodging clouds and hailstorms all week I was able to record my first solar image at the CaK wavelength… 393.37nm in the violet end of the spectrum. I see almost no detail visually due to my eye’s poor sensitivity at this wavelength. But the camera sees good!” — Alan Friedman

Herschel crater on Mimas of Saturn
Why is this giant crater on Mimas oddly colored? Mimas, one of the smaller round moons of Saturn, sports Herschel crater, one of the larger impact craters in the entire Solar System. The robotic Cassini spacecraft now orbiting Saturn took the above image of Herschel crater in unprecedented detail while making a 10,000-kilometer record close pass by the icy world. Shown in contrast-enhanced false color, the above image includes color information from older Mimas images that together show more clearly that Herschel’s landscape is colored slightly differently from more heavily cratered terrain nearby. The color difference could yield surface composition clues to the violent history of Mimas. An impact on Mimas much larger than the one that created the 130-kilometer Herschel would likely have destroyed the entire world.
