Google "supernova remnant" and you'll find plenty of similar pictures.

Why are people so consistently fooled by anything roughly circular with a bright edge in the top-left of the picture? Maybe it's too much exposure to computers where that same optical illusion is used to make buttons look like solid objects - and people somehow forget they're still only flat pictures on the screen.

In space the sun isn't shining down on everything from above.

Turn it upside down and see if it still looks like an object.
