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. (TV: Colony in Space) This is believed to have occurred either during the Millennium War circa 150 million BC (PROSE: The Quantum Archangel) or circa 5300 BC (TV: Colony in Space). This supernova became visible on Earth in 1054. (TV: Colony in Space)

The planet Wengrol was located in the Crab Nebula (PROSE: The Sons of the Crab), as was the planet Tora (COMIC: The Enlightenment of Ly-Chee the Wise).

In the 51st century, humanity relocated to the Crab Nebula after Earth was ruined by solar flares. (COMIC: The Keep)

The Tenth Doctor took Grayla to either the Crab Nebula or the Horsehead Nebula. (COMIC: The Whispering Gallery)
