SCIENTISTS FIND EXISTENCE OF DARK MATTER

A team of U.S. scientists has found the first direct evidence of the existence of 'dark matter,' a little-understood substance with a huge influence on gravity, the team's leader said in Boston, Massachusets on August 23, 2006. The NGC 2300 group of galaxies contains a large reservoir of million-degree gas glowing in X-rays. A false-color X-ray image of the hot gas is superimposed here on an optical picture of the galaxy group. Gravity from the galaxies alone is not enough to keep the gas in its place. There must be large quantities of dark matter whose gravity is preventing the gas from escaping. (UPI Photo/NASA)
