Gomez's Hamburger is actually a preplanetary nebula. The buns are where light is illuminating dust and the patty is a torus of dust so thick that the star in the center is rendered invisible. Pretty cool!

For this one I used the set of optical data and then added some NICMOS infrared data to reveal the shape of the dust torus. Infrared data from NICMOS is really neat, but it also tends to be rather messy as far as aesthetics go so I limited it to just the torus. That, and it only extends a little way out from the nebula, otherwise I'd love to include infrared for the entire picture.

North is NOT up. It's 40° clockwise from up.
