The Universe is all of time and space and its contents. The Universe includes planets, stars, galaxies, the contents of intergalactic space, the smallest subatomic particles, and all matter and energy. The observable universe is about 28 billion parsecs (91 billion light-years) in diameter at the present time, though the size of the whole Universe is not known and may be infinite.
Human beings have been captivated and inspired by the night sky since the beginning of recorded history. From the ancient Egyptians to the Mayans to the Greeks, we have always been fascinated by what else is or may be out there. Nearly every kind of mythology has a relationship with outer space and many constellations and stars have names derived from ancient Greek mythology. Art created during these periods reflected this tie as well.
Pieces celebrate the vast beauty or danger of outer space and include planets, stars, star systems, galaxies, solar systems, mythology and culture references to outer space, and interpretations of advancement in space travel and the future of outer space exploration.
