Take a little break.

There really is so much going on in the Universe. 

Looks cool, but is it?

Gulf of America, harumph.

The Universe unveiled.

Could it be magic?

It's called the Fireworks Galaxy because it's had 10 supernovae since 1917. It's also 25 million light-years away, so we're seeing a much younger galaxy forming new stars.

Another nice galaxy.

And another nice galaxy. Comfortable. Real homey.

These are emission nebulae in Vulpecula — star-forming regions glowing because they are being ionized by massive type O stars. The mnemonic for stellar types goes with the letters OBAFGKM. When I was an undergrad, the mnemonic was Oh Be A Fine Girl, Kiss Me. I'm told they don't use that any more. In any case, our Sun is type G.

I'm trying to work up a reference to the Blues Brothers, but I'm not finding it.

This is a planetary nebula from the collapse of a medium-size star about 65,000 years ago, lit from inside by the white dwarf that remains. The surface temperature of the white dwarf is about 120,000 K (or about 120,273°C, more or less.)

So, maybe a little video game while we take our break.

And that's your Sky Candy for this week, with hopes for a quiet news weekend. As always, I hope you'll be back next week, and don't forget the Sunday Supplement.

Oh, and comment and make the editors feel good.
