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 area right around the pulsar looks like an eye.

It’s not often you can look at an astronomy picture and see exactly what’s going on.
That one was fun!
So was finding the Enterprise in the last one!

But, you didn’t find the cheeseburger.

I didn’t.
But I could see it after someone pointed it out.

They are actually everywhere. There may not be anything else. Like a fundamental building burger.

Burger Theory is a lot more appetizing than String Theory.

Trying to post two more images of Crab, Visible Light Only, from Hubble:
Honestly, I do not understand
how the heck the top image corresponds to the other three, but it is clearly the same as the multiple-wavelength image you show, but it is "visible", perhaps "false color", light.

OOPS: I just noticed some of the pix I posted were of the “SOUTHERN CRAB” —— Sorry, all... they are pretty anyway...
