"The Boomerang is a cloud of dust and gas being spewed out from an old star while its core collapses inward and becomes a white dwarf, a star which has used up its nuclear fuel," according to Sahai, who co-discovered the cold region. "The Boomerang Nebula is like a cosmic refrigerator, in which expanding gas cools very efficiently down to the very chilly temperatures we have found."
