This planetary nebula, Mz3, is being cast off by a star similar to our Sun. The 1000-kilometer per second speed of the expelled gas, the light-year long length of the structure, and the magnetism of the star visible at the nebula's center, all imply Mz3 is hiding a second, dimmer star that orbits close in to the bright star. A competing hypothesis holds that the central star's own spin and magnetic field are channeling the gas. (ESA, NASA's Hubble, JPL-CalTech)
A dying star throws a cosmic tantrum in this combined image from Nasa's Spitzer Space Telescope and the Galaxy Evolution Explorer. The star's dusty outer layers are unraveling into space, glowing from the intense ultraviolet radiation being pumped out by the hot stellar core. This object, called the Helix nebula, lies 650 light years away in the constellation of Aquarius
Cloud Nine? Hubble captures 'face of God' in plumes of space dust (although the Second Coming might be delayed, as He is 75 million light years away)
#Astronomy : Hubble seems to have pinpointed 'Cloud Nine' a little further off, in an elliptical galaxy 75 million light years from Earth. If the ghostly face is in fact the Heavenly Father, he may be trying to communicate with his children on Earth - #NGC1316 is one of the most powerful radio sources in the sky.
Astronomers have discovered the largest known structure in the universe, a clump of active galactic cores that stretch 4 billion light-years from end to end. The structure is a light quasar group (LQG), a collection of extremely luminous Galactic Nuclei powered by supermassive central black holes.
Incredible New Observation Shows Supermassive Black Holes Orbiting Each Other - Press release art that doesn’t at all accurately depict what orbiting black holes 24 light years away would look like but does look pretty nice (Image: Joshua Valenzuela/UNM)
(Picture: Nasa, ESA, and The Hubble Heritage Team STScI/AURA) The Carina Nebula is a cloud of dust, hydrogen, helium and other gases around 7,500 light years away from Earth. In this picture the oxygen is blue, hydrogen and nitrogen are green and sulphur red.
