This was totally new to me.  Explained at NASA's Astronomy Photo of the Day and at this Wikipedia entry.

  1. Gorgeous picture!

    I know you already have a reading list to last multiple lifetimes, but if you haven't checked it yet, I think you'll greatly enjoy The Cloudspotter's Guide by Gavin Pretor-Pinney (founder of the Cloud Appreciation Society).

  2. Ah, I see my halo is waiting for me, shame I'm going the other way.

  3. China has been doing a ton of cloud seeding to fight off a drought, wonder if this could be related at all?

    1. Not saying it couldn't, but cloud iridescence is a completely natural phenomenon. No chemicals (other than water) needed!
