Crab Nebula

The Crab Nebula was a nebula remnant of a supernova located within the galaxy of Mutter's Spiral about 6500 light years away from Earth. It was created by the Uxarieans by detonating a star with their Doomsday Weapon. (DW: Colony in Space) This is believed to have occurred either during the Millennium War circa 150 million BC (PDA: The Quantum Archangel) or circa 5300 BC (DW: Colony in Space). This supernova became visible on Earth in 1054. (DW: Colony in Space)
