Small, Low Surface Brightness Galaxies Are Very Common Investigators at the Niels Bohr Institute announce the discovery of some low surface brightness galaxies, in a finding that proves these structures are more common throughout the Universe than anyone originally thought. These galaxies stand out through the fact that they are very small, but also because experts have ... 15 June 2011 04:24 GMT The Periodic Table Now Features Copernicium The International Union of Pure and Applied Chemistry (IUPAC) has officially recognized the name of the heaviest chemical in the world, until now named Element 112. The substance was called thus because it features 112 protons in its nucleus. This makes it about 277 times heavier than hydrogen, and the heaviest atom ... 25 February 2010 05:32 GMT 'Islands of Stability', the Holy Grail of Physicists The heavy elements occupy an area of the periodic table where other elements cannot be, and decay in fractions of seconds - an island in the sea, as nuclear physicists like to call it. This caused scientists to believe that other such islands, 'island of stability', may exist well beyond some of the superhe... 7 April 2008 05:01 GMT
