Horsehead Nebula

The Horsehead Nebula (above) is a dark nebula in the constellation Orion, located just to the south of the star Alnitak, which is farthest east on Orion's Belt, and is part of the much larger Orion Molecular Cloud Complex. It was first recorded in 1888 by Scottish astronomer Williamina Fleming on photographic plate B2312 taken at the Harvard College Observatory.

Plutonium

Plutonium is basically a radioactive chemical element, an actinide metal of silvery-gray appearance, that tarnishes when exposed to air, and forms a dull coating when oxidized.
