Royal Astronomical Society 21 Apr 2009, 00:10 UTC A team of astronomers from University College London (UCL), including undergraduate students, have discovered that an exotic world passes directly in front of the Sun-like star it orbits, revealing for the first time that it is about the same size as Jupiter. And rather than travelling to one of the major observatories in Hawaii or Chile, the students made the discovery with a telescope at UCL's University of London Observatory (ULO) in the capital's northern suburb of Mill Hill.
Royal Astronomical Society 21 Apr 2009, 00:10 UTC An international team of scientists has found that giant exoplanets orbiting very close to their stars could lose a quarter of their mass during their lifetime. The team found that planets that orbit closer than 2% of an Astronomical Unit (AU), the distance between the Earth and the Sun, may lose their atmospheres completely, leaving just their core. The team, led by Dr Helmut Lammer of the Space Research Institute of the Austrian Academy of Sciences, believe that the recently...
NASA's Spitzer Space Telescope 20 Apr 2009, 20:00 UTC Using the infrared detectors on NASA's Spitzer Space Telescope, a team of researchers based in the U.K. and in the United States have placed new constraints on how often rocky planets like Earth may exist around stars other than our Sun.
Royal Astronomical Society 20 Apr 2009, 17:46 UTC An international team, led by astronomers at the University of Hertfordshire in the UK, have discovered one of the coolest sub-stellar bodies ever found outside our own solar system, orbiting the red dwarf star Wolf 940, some 40 light years from Earth. Dr Ben Burningham of the University of Hertfordshire will present this discovery on Monday 20th April at the European Week of Astronomy and Space Science conference.
Royal Astronomical Society 20 Apr 2009, 17:46 UTC Astronomers using the United Kingdom Infrared Telescope (UKIRT) in Hawaii, the IRAM Millimetre-wave Telescope in Spain, and the Spitzer Space Telescope in orbit above the Earth, have completed the most wide-ranging census ever produced of dynamical star formation in and around the well-known Great Nebula of Orion.
ESA Top News 15 Apr 2009, 08:00 UTC Studying satellite radar data from ESA’s Envisat and the Italian Space Agency’s COSMO-SkyMed, scientists have begun analysing the movement of Earth during and after the 6.3 earthquake that shook the medieval town of L’Aquila in central Italy on 6 April 2009.
