The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation Cygnus. It constitutes the visible portions of the Cygnus Loop (radio source W78, or Sharpless 103), a large but relatively faint supernova remnant. The source supernova exploded some 5,000 to 8,000 years ago, and the remnants have since expanded to cover an area roughly 3 degrees in diameter (about 6 times the diameter, or 36 times the area, of the full moon). Seen here is the the Eastern Veil Caldwell 33.

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 lumino

Keyhole Nebula - A portion of the Carina Nebula is known as the Keyhole Nebula (NGC 3324), a name given to it by John Herschel in the 19th century. The Keyhole Nebula is actually a much smaller and darker cloud of cold molecules and dust, containing bright filaments of hot, fluorescing gas, silhouetted against the much brighter background nebula.

IC 342, the Hidden Galaxy, is positioned only 10 degrees above the plane of our Milky Way Galaxy, so its light is heavily obscured and reddened by dust. It is 7 million light-years away but is not part of our Local Group of galaxies.

Lightning in space:  A single bolt of lightning is 50 percent longer than the entire Milky Way galaxy.Scientists have observed lightning on Mars and Saturn but didn't know that lightning could occur in the middle of space, with a force equal to a trillion lightning bolts, or to use the proper scientific terms, 50 million tons of electricity.  This insane electrical current was discovered near galaxy 3C303 firing a massive jet of electrified matter 150,000 light-years into outer space.
