Moon Halo over Stone Circle

Oddly enough, this weekend while out playing golf, I noticed a Sun halo and posted this picture. You may have to be logged in to see it.

Edit: Yep, just tested it - you have to be logged in. Here it is:

The Red Rectangle Nebula from Hubble

I have never seen this before, very interesting.

Yes, that's a cool one alright but my preference for spinning symmetry on the sky means The Red Square* Nebula gets my vote. Here's Peter Tuthill's page that describes and 3-d models the object and that will have similarities in the Red rectangle... :thumbup:

Featured in an apod in January 2016.
