Gomez's HamburgerGomez's Hamburger is a "proto-planetary nebulae," or a star that is in a state of evolution immediately before the true planetary-nebula stage. It was discovered on sky photographs obtained by Arturo Gomez, an astronomer at the Cerro Tololo Inter-American Observatory in Chile. The photos suggested that there was a dark band across the object, but its exact structure was difficult to determine because of the atmospheric turbulence that hampers all images taken from the ground. The star itself has a surface temperature of approximately 10,000 C (18,000 F). The "hamburger buns" are light reflecting off dust, and the "patty" is the dark band of dust in the middle.
