Aurora Slathers Up the Sky
Explanation: Like salsa verde on your favorite burrito, a green
aurora slathers up the sky in this 2017 June 25 snapshot from the International Space Station. About 400 kilometers (250 miles) above Earth, the orbiting station is itself
within the upper realm of the auroral displays. Aurorae have the
signature colors of excited molecules and atoms at the low densities found at extreme altitudes. Emission from atomic oxygen dominates this view.
The tantalizing glow is green at lower altitudes, but rarer reddish bands extend above the space station's horizon.
The orbital scene was captured while passing over a point south and east of Australia, with stars above the horizon at the right belonging to the constellation
Canis Major, Orion's big dog.
Sirius, alpha star of Canis Major, is the brightest star near the Earth's limb.

Yeah... if your pizza looks like that, it's been sitting in the back of the fridge for a little too long. I'd advise against eating it!
