Dutch Teacher finds “Space Ghost”

Dutch Teacher Stumbles Upon A Space ‘Ghost’ : NPR
A Dutch primary school teacher has accidentally discovered what some are calling a cosmic space “ghost” — a strange, greenish, gaseous object with a hole in the middle that may represent a new type of astronomical phenomena.
The teacher, Hanny van Arkel, stumbled upon the cosmic object in 2007 while doing volunteer work for Galaxy Zoo, a Web site that enlists the public’s help in identifying galaxies.
