In August of 2007, astronomers located a gigantic hole in the universe. This empty space, stretching nearly a billion light-years across, is devoid of any matter such as galaxies, stars, and gas, and neither does it contain the strange and mysterious dark matter, which can be detected but not seen. The large void in the Constellation Eridanus appears to be improbable given current cosmological models. A radical and controversial theory proposes that it is a "universe-in-mass black hole"

Thor’s Helmet Nebula - NGC 2359 (also known as Thor's Helmet) is an emission nebula in the constellation Canis Major. The nebula is approximately 15,000 light-years away and 30 light years in size. The central star is the Wolf-Rayet star HD 56925, an extremely hot giant thought to be in a brief, pre-supernova stage of evolution

The Dandelion Cluster is a group of stars located 5000 light years away from us, backdropped by the center of the galaxy. This cluster collapsed from a large gas cloud about 200 million years ago and weighs about 300 solar masses. Remnants of the cloud are visible, blocking light from the stars behind them. There are so many stars….

NASA's Hubble Space Telescope has unveiled in stunning detail a small section of the expanding remains of a massive star that exploded about 8,000 years ago. Called the Veil Nebula, the debris is one of the best-known supernova remnants, deriving its name from its delicate, draped filamentary structures. The entire nebula is 110 light-years across, covering six full moons on the sky as seen from Earth, and resides about 2,100 light-years away in the constellation Cygnus, the Swan.
