Explanation: The Crab Nebula is cataloged as M1, the first object on Charles Messier's famous list of things which are not comets. In fact, the Crab is now known to be a supernova remnant, expanding debris from massive star's death explosion, witnessed on planet Earth in 1054 AD. This brave new image offers a 21st century view of the Crab Nebula by presenting image data from across the electromagnetic spectrum as wavelengths of visible light. From space, Chandra (X-ray) XMM-Newton (ultraviolet), Hubble (visible), and Spitzer (infrared), data are in purple, blue, green, and yellow hues. From the ground, Very Large Array radio wavelength data is shown in red. One of the most exotic objects known to modern astronomers, the Crab Pulsar, a neutron star spinning 30 times a second, is the bright spot near picture center. Like a cosmic dynamo, this collapsed remnant of the stellar core powers the Crab's emission across the electromagnetic spectrum. Spanning about 12 light-years, the Crab Nebula is 6,500 light-years away in the constellation Taurus.

That one’s cool!
I’m thankful we have 6500 light years of space separating us from what’s at the center of that thing.
Considering that the pulsar at the center is providing the energy to illuminate something 12 light years across, I agree with you.
I’m sure there is plenty of fractal patterns at various magnifications.
The central neutron star, spinning 30 times per second, wold be something to see if the radiation did not kill you before you could say wow!
nice
Looks like an acid rock concert prop.
Not that I would know, of course.
Ummm, saying for a friend...
Not going to ask how you know about mushrooms. Not going to ask, but it looks like you know.

Visualize a sphere 16 miles in diameter, made of the densest material in existence, of which a teaspoon has more mass than an aircraft carrier. Then visualize this huge, inconceivably massive sphere turning completely on its axis 30 times a second.
The tangential velocity of the surface of the sphere is a substantial fraction of the speed of light.
It boggles my mind.
God was having way too much fun when He made this. Srsly.
Well, maybe not “substantial” fraction. Still, pretty d@mn fast.

Yes, and it generates a magnetic field that is billions of times more powerful than that of Earth.
According to its Wikipedia page, it radiates photons that each carry over 100 TeV of energy.
The gamma ray photons emitted by the decay of radium average about 0.74 MeV each; a 100 TeV photon carries a hundred million times more.
Crabs are not to be taken lightly
Wow. Thanks
You have hotdogs there several times, but the things that show up the most in astronomy that are not comets are definately cheeseburgers.
I could go for a good cheeseburger right about now.
One with good old American cheese.
Not some of that fancy cheddar cheese.
