8th ring discovered around Saturn


Right here, thanks to Telegraph.co.uk

8th ring discovered around Saturn. Well crap, why didn’t see see this sooner? It turns out that the ring is only visible in the thermal band, not the visible spectrum that we’ve been staring at it for so long with. When you point Nasa’s Spitzer Space Telescope (which observes in infrared) at it, you get the grand view of the rings, which start at 3.7 million miles out from Saturn and extend an additional 7.4 million miles. Composed of simply space dust, it was observed at a chilly -316F, or about 80 Kelvin.

Thanks to @waybis for pointing this out!
