Using infrared imagining, scientists have discovered a new, huge ring around Saturn. So diffused that you wouldn't see it if you were in it, and big enough that it would take a billion Earths to fill it.
Though I must confess, I didn't find this as impressive as the event of March 10, 1977, by James L. Elliot, Edward W. Dunham, and Douglas J. Mink, who discovered that there were rings around another planet in our solar system.
And a great topic of party conversation:
So, who's that?
Why, that's Jim Elliot, the famous astronomer.
Yeah? Famous for what?
That's the man who discovered that there are rings around Uranus!
