Boomerang Nebula

The Boomerang Nebula, called the “coldest place in the universe,” is located 5,000 light-years away from Earth in the constellation Centaurus. The background blue structure, as seen in visible light with the Hubble Space Telescope, shows a classic double-lobe shape with a very narrow central region. Atacama Large Millimeter/submillimeter Array (ALMA)’s resolution and ability to see the cold molecular gas reveals the nebula’s more elongated shape, as seen in red. ALMA is an international astronomy facility that is a partnership of Europe, North America and East Asia in cooperation with the Republic of Chile. It is funded in part by the National Science Foundation.
