HOW COLD CAN SPACE GET?
A young planetary nebula located 5,000 light years from Earth in the constellation of Centaurus, the Boomerang Nebula is the coldest object we have found in the universe thus far. The nebula – whose name comes from its curved asymmetric shape – has a temperature of -272 degrees Celsius, just one degree warmer than absolute zero. Its incredibly cold temperature could be the result of the fact that the nebula is expanding rapidly. The Boomerang
Nebula’s shape appears to have been caused by ultracold gas being blown away from a dying star at its heart by powerful 311,000 mile per hour winds.
