10 light years across? That’s a lot of butter and where do you find an 11 light year wide bowl to hold that kind of butter?

It looks more like a body louse but Body Louse Nebula just wouldn’t sound right. ;^)

There’s a thermal feature in Yellowstone that looks similar to this. Cool.

Anyone know why this has such irregular edges, rather than a perfect sphere?

1054 is the year usually attributed as the beginning of the formal Great Schism. I wonder if folks wondered about that back then, as in a “signs and wonders in the sky” sort of thing. I have poked around a little and some sites have it happening in the same week. Don’t know if that’s true or not. I guess it was visable for two years or so, and you could see it during the day for 23 days.

Now that would be some serious pre-planning, like 6,500 years!
