Gamma Ray Earth !! ...? (APOD 03Jun06)
Looking at today's Gamma Earth...........if you consider Chernobyl, Hiroshima, Christmas Island and Maralinga............it's quite uncanny but maybe fits the image ? [/b]

Brightest near the edge and faint near the center, the picture indicates that the gamma rays are coming from high in Earth's atmosphere. The gamma rays are produced as the atmosphere interacts with high energy cosmic rays from space, blocking the harmful radiation from reaching the surface.

hi brianclark,
considering its a 7 year exposure... and this observatory was placed in a 450km orbit (likely not equatorial), I would say that its unlikely the spots represent exact locations as you suggest
on the other hand I have no idea how they went about taking that image... it seems a little unlikely that they got an image with such an emphasis on one side over a whole 7 years... am I missing something?
