Halloween In Space: Creepy Entities Discovered In The Universe
As Halloween approaches, we look to the mysterious depths of the universe and find ghostly apparitions, spectral hands, skulls, wizards and witches. Or at least these are the descriptions applied by NASA to the jaw-dropping observations they have made.
Nicknamed the "Hand of God," this object is called a pulsar wind nebula. It's powered by the leftover,dense core of a star that blew up in a supernova explosion. The stellar corpse,called PSR B1509-58,or B1509 for short,is a pulsar: it rapidly spins around,seven times per second,firing out a particle wind into the material around it -- material that was ejected in the star's explosion.
