We’ve already been treated to spectacular black and white closeup images of Saturn, beamed home to Earth by the Cassini spacecraft after it dove between the planet and its rings. Now, we’re getting to see what things look like in true color.
Among the first of these images is the one above, processed by Sophia Nasr, an astro-particle physicist working on dark matter. She will begin her PhD studies in physics at UC Irvine in September 2017. (For her full bio, see the end of this post.) I first spotted Nasr’s image on Twitter, where she may be posting more. You can find her here: [link to twitter.com (secure)]
That striking, sky-blue feature is the eye of a persistent hurricane at Saturn’s north pole. The feature is 1,200 miles across, about 20 times larger than the average hurricane eye on Earth. And clouds are swirling around it as fast as 330 miles per hour.
The striking cerulean color is not at all false. It comes from scattering of sunlight, the same phenomenon that produces a blue sky here on Earth.
