In 1054 A.D., Chinese astronomers recorded the temporary brightening of a star in the constellation Taurus. Nearly 1000 years later, we look in the same region and see the exploded remnants of a dead star: the Crab Nebula. This composite photograph of the Crab Nebula was made by merging images from Hubble, the Chandra X-Ray Observatory, and the Spitzer Space Telescope. It shows only a hail of high-energy particles and expanding debris cloud that once was a massive star.

Hi,
If one were to remove the Spitzer infra red and the Chandra X-ray blue coloring from the image, the remaining Hubble optical green and blue coloring represents what?
Thanks

Best image of the Crab that I've ever seen. Fabulous!

I think the midline of the greens (upper left to lower right) defines the zero latitude on the predecessor star, and the reds (to the upper right and lower left) the poles. Probably not what you were asking, but if correct, a real credit to this image.

when a nebula like this expanding, why cant we consider the whole universe is a nebula like this and still expanding accepting the `big bang'.,
and there are set of endless universes exploding and expanding still...with no beginning and no end
