Ring of Fire

Here's a story I meant to post a few days ago. It's from the web site io9.com:

Ring of fire forms around a new supernova

"A 6-trillion-mile-wide ring of gas encircles a supernova in the Large Magellanic Cloud, Supernova 1987A, and the explosions from the supernova are lighting it up like a candle, creating what will become a glowing ring."

Six trillion miles. Another example of how the scale of cosmic events is simply beyond comprehension. And relatively speaking, this is just a tiny thing.
