Explanation: This is the mess that is left when a star explodes. The Crab Nebula, the result of a supernova seen in 1054 AD, is filled with mysterious filaments. The filaments are not only tremendously complex, but appear to have less mass than expelled in the original supernova and a higher speed than expected from a free explosion. The above image, taken by the Hubble Space Telescope, is presented in three colors chosen for scientific interest. The Crab Nebula spans about 10 light-years. In the nebula's very center lies a pulsar: a neutron star as massive as the Sun but with only the size of a small town. The Crab Pulsar rotates about 30 times each second.

Not just you. We can hallucinate froggies together! Look! It's pretty and blue, too!
As usual, we need Dr. Rorschach. Sigh...

I've had bad experiences with him.
Thanks a bunch, I'd almost succeeded in blotting him out of my memory.

Oh! Oops. Sorry! How can I make it up to you? I'll never mention his name in your presence again.
Besides, it is a very pretty frog.

Heck, Nully! Now you said it. I like the "Watchmen" character, but that's about it.
And I like The Comedian better, not the FReeper, but the character.

The Comedian, now there’s one old FReeper I’d really like to talk to.
Heck, I’d even buy him a beer...

He was nice to me...
So, you didn’t do so well on an inkblot test? Couldn’t see the butterflies, flowers, and vases, huh. Nobody’s perfect.

The mass of the sun, 5 miles across, spinning around 30 times a second, with its magnetic field off kilter ......
A single cubic meter of the magnetic field in the Crab pulsar contains more energy than humans have been able to generate, to date.
...it just amazes me, all of these totally accidental things that just randomly happen. /sarc

30 Hertz, half the frequency of house current. No wonder it pulses.

Actually I see a bear in the bluish area, facing at 3/4 away from the viewer, front legs braced and sitting back slightly on his haunches.

McCroskey: Johnny, what can you make of this?
[hands Johnny a map]
Johnny: This? Well, I can make a hat; I can make a broach; I can make a teradactyl!

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

No! I am kidding. Sorry for having you on, and it was a great pun and I laughed. But it was funny watching you try to make me get it, LOL! Oh, sorry again!
