 Distant "Super-Starburst" Galaxies Hide Active Black Holes - SpaceDaily  Left:  These radio emission contours overlay false colour images taken with the Hubble Space Telescope's Advanced Camera for Surveys. Each image is approx. 2.6 arcsec on a side and the radio and X-ray peaks are shown in red and blue respectively. In each case the X-ray emission is thought to come from an active supermassive back hole concealed within a dusty torus. J123622+621629 (top) and J123621+621109 (right), at redshifts of 2.4 and 1 respectively (70 and 20 billion light years distant), have extended radio emission typical of starbursts and are associated with distorted, probably merging optical galaxies.  The team focused on galaxies so far away that their radiation took more than six billion years to reach us. The galaxies are seen as they were when they were less than half the age that the Universe is today. "The more remote starburst galaxies, so called because of their high rate of star formation, typically produce 1,000 or more solar masses of stars per year - at least 50 times more than the most active star-forming galaxies in the nearby Universe," said Dr. Richards. "Each distant starburst region is tens of thousands of light years across, equivalent to about the inner quarter of the Milky Way - also vastly larger than any such regions found in our part of the Universe. We concluded that, not only were these young galaxies undergoing much more violent and extended star formation than we see today, but they were simultaneously feeding active, supermassive black holes responsible for the X-ray emission," said Richards.
"Earths" Galore Await Discovery - SpaceDaily  Recent theoretical work by Barrie Jones, Nick Sleep, and David Underwood at the Open University in Milton Keynes indicates that as many as half of the known systems could be harbouring habitable "Earths" today. Unfortunately, existing telescopes are not powerful enough to see these relatively small, distant "Earths". "We were particularly interested in the possible survival of "Earths" in the habitable zone," said Professor Jones. "This is often called the 'Goldilocks zone,' where the temperature of an 'Earth' is just right for water to be liquid at its surface. If liquid water can exist, so could life as we know it."    

LISA And The Search For Gravity Waves - SpaceDaily  Left:  "LISA (Laser Interferometric Space Antenna) (illustrated) is expected to provide the best chance of success in the search for the exciting, low frequency gravity waves," said Professor Cruise. "However, the mission is one of the most complex, technological challenges ever undertaken."  In the case of LISA, three spacecraft will fly in formation, 5 million kilometres apart. Laser beams travelling between them will measure the changes in separation caused by gravity waves with a precision of about 10 picometres (one hundred thousandth of a millionth of a metre). The precision required is 1,000 times more demanding than has ever been achieved in space before.
