ESO Top News 4 Jun 2009, 08:00 UTC ESO 21/09 - Science Release:Using ESO's Very Large Telescope, astronomers have obtained one of the sharpest views ever of the Arches Cluster - an extraordinary dense cluster of young stars near the supermassive black hole at the heart of the Milky Way. Despite the extreme conditions astronomers were surprised to find the same proportions of low- and high-mass young stars in the cluster as are found in more tranquil locations in our Milky Way.

ASI Agenzia Spaziale Italiana 3 Jun 2009, 16:27 UTC Using new data from ESA’s XMM-Newton observatory (a European space telescope built with relevant Italian contribution), astronomers have probed closer than ever to a supermassive black hole lying deep at the core of a distant active galaxy. The galaxy – known as 1H0707-495 – was observed during four 48-hr-long orbits of XMM-Newton around Earth, starting in January 2008. The black hole at its centre was thought to be partially obscured from view by intervening clouds of gas and dust, but these current observations have revealed the innermost depths of the galaxy. “We can now start to map out the region immediately around the black hole,” says Andrew Fabian, at the University of Cambridge, who headed the observations and analysis. X-rays are produced as matter swirls into a supermassive black hole. The X-rays illuminate and are reflected from the matter before its eventual accretion. Iron atoms in the flow imprint characteristic iron lines on the reflected light. The iron lines are distorted in a number of characteristic ways: they are affected by the speed of the orbiting iron atoms, the energy required for the X-rays to escape the black hole’s gravitational field, and the spin of the black hole. All these ...

NASA's Jet Propulsion Laboratory News and Features 3 Jun 2009, 07:00 UTC Cloud chasers studying Saturn's moon Titan say its clouds form and move much like those on Earth, but in a much slower, more lingering fashion.
Arianespace Press Releases 3 Jun 2009, 00:00 UTC Arianespace has received the heavy-lift Ariane 5 for its upcoming mission with the world's largest commercial telecommunications satellite to be launched – TerreStar-1. This vehicle was delivered to the Final Assembly Building today, where preparations will begin for the late June liftoff on Arianespace's third flight of 2009
Japan Aerospace Exploration Agency Press Releases 2 Jun 2009, 08:30 UTC The Japan Aerospace Exploration Agency (JAXA) is inviting members from six space agencies in the Asia-Pacific Region to participate in the Satellite Technology for the Asia-Pacific Region (STAR) Program, which JAXA introduced at the Asia-Pacific Regional Space Agency Forum (APRSAF) held in 2007. The STAR Program will be conducted from 1 June 2009 (TBD), and activity at JAXA's Sagamihara campus has already begun.
