"We already knew there was something different about this spot in the sky," Rudnick said. The region stood out as being colder in a survey of the Cosmic Microwave Background -- the faint radio buzz left over from the Big Bang that gave birth to the Universe.
"What we've found is not normal, based on either observational studies or on computer simulations of the large-scale evolution of the Universe," Williams said in a statement.
The astronomers said the region even appeared to lack dark matter, which cannot be seen directly but is usually detected by measuring gravitational forces.
The void is in a region of sky in the constellation Eridanus, southwest of Orion.
