Deep Pan Earth

Have you ever thought that the Earth looked like a pizza? It never crossed my mind until now. In a new image, created by Dr. Dirk Petry of NASA Goddard Space Flight Center, the Earth does vaguely resemble a deep pan pizza with extra green peppers and tomato. The image shows us what the Earth would look like if you could see gamma rays - light that has billions of times more energy that the light we normally see with. It was created using seven years worth of data from the Compton Gamma-Ray Observatory. The red image corresponds to gamma rays at 35-100 MeV (mega electron volts); the green image corresponds to gamma rays at 100 MeV to 1 GeV; the blue image corresponds to gamma rays at 1-10 GeV; and the brownish image shows the full mix of energies. The satellite was at an altitude of about 420 km so the image has an extreme wide-angle view.
