A pair of researchers at the Czech Academy of Sciences has been shaking up the astrophysics community with a new modified Newtonian dynamics (MOND) theory that tosses out the concept of dark matter and instead backs up theories ...
Hubble Space Telescope's glamor shots of the universe are so revealing they nearly always have a discovery behind them.
