Caption: The Boomerang Nebula, called the "coldest place in the Universe," reveals its true shape with ALMA. 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. ALMA's resolution and ability to see the cold molecular gas reveals the nebula's more elongated shape, as seen in red.
