There's a beautiful pic & the article is very informative too.</font></p><p><font size="2"><font size="2">Colliding galaxies reveal colossal black holes were common in early Universe</font>&nbsp; </font></p><p><font size="2">New observations made with the Submillimeter Array of eight radio antennas atop the extinct volcano on the island of Hawaii suggest that black holes &ndash; thought to exist in many, if not all, galaxies &ndash; were common even in the early Universe, when galaxies were just beginning to form. Astronomers have found two very different galaxies in the distant Universe, both with colossal black holes at their heart, involved in a spectacular collision.</font></p><p><font size="2">4C60.07 &ndash; the first of the galaxies to be discovered &ndash; came to astronomers&rsquo; attention because of its bright radio emission. This radio signature is one telltale sign of a quasar &ndash; a black hole, spinning rapidly, feeding on its parent galaxy. A new image captures the moment, approximately 12 billion years ago, when this galaxy ripped a stream of dusty gas from a neighbour.</font></p> <div class="Discussion_UserSignature"> <font color="#993300"><span class="body"><font size="2" color="#3366ff"><div align="center">. </div><div align="center">Never roll in the mud with a pig.
