The Witch Head Nebula

I posted this back in June but thought I would bring it forward since it's so fitting for Halloween:

Explanation: Double, double toil and trouble; Fire burn, and cauldron bubble ... Maybe Macbeth should have consulted the Witch Head Nebula. This suggestively shaped reflection nebula is associated with the bright star Rigel in the constellation Orion. More formally known as IC 2118, the Witch Head Nebula glows primarily by light reflected from Rigel. Rigel is located about one photo-width off the image to the right. Fine dust in the nebula reflects the light. The blue color is caused not only by Rigel's blue color but because the dust grains reflect blue light more efficiently than red. The same physical process causes Earth's daytime sky to appear blue, although the scatterers here are molecules of nitrogen and oxygen. The nebula lies about 1000 light-years away.

Hey, isn't that Mann Coulter's profile? Hehehehe.
Off-topic: What's up w/GiFS? Keep getting the Internal error from server message.

ka -
Isn't that doing injustice to witches to compare them with the MAnn? :)

As for GifS - it appears some troll scum hacker did something to prevent the site from coming up. They have been working on it since yesterday. We did have a threat by a disgruntled "asshatted" xian troll of giving us a virus. We laughed it off as most of the time xians fundies who troll can hardly read, much less hack into a system. If this is the case, it will be found through the usage tracker and turned into proper federal authorities. We will be up and running again, it's just a matter of changing server hosts or something like that.

AhAH! I thought I'd see that somewhere before.

Ghoulish!

Happy Helloween, Lady Stardust! The one night where all those ghosts ghouls and goblinie things are actually really. I Love it!

Young and old, Halloween makes people happy because no matter what age, people need to use their imagination and get away from reality for awhile.
(Maybe that is why many people need religion?)
