ESO Top News 6 May 2009, 15:05 UTC ESO 18/09 - Instrument Release:Scientists and engineers working on the world's largest ground-based astronomical project, the Atacama Large Millimeter/submillimeter Array (ALMA), have achieved another milestone - the successful linking of two ALMA astronomical antennas, synchronised with a precision of one millionth of a millionth of a second - to observe the planet Mars. ALMA is under construction by an international partnership in the Chilean Andes.

ASI Agenzia Spaziale Italiana 4 May 2009, 21:40 UTC Too many electrons, too high energy. That's what turned out in new data gathered by the Fermi Gamma-ray Space Telescope. The electrons could be coming from nearby pulsars—or they could be a longed-for signal of dark matter, the elusive, invisible material thought to make up nearly a quarter of the universe.FGST’s Large Area Telescope, a collaboration between NASA, the U.S. Department of Energy, and multiple international partners (built with an important Italian contribution, coordinated by the Italian Space Agency with the National Institute of Nuclear Physics and the National Institute for Astrophysics), has been scanning the skies for gamma rays and particles since its launch last summer. The LAT measured a strikingly high number of electrons with energies between 100 billion and one trillion electronvolts. It is not known from the LAT data alone if these electrons are coming from the distant background, or are the signal of a nearby source of high-energy particles.“If these particles were emitted far away, they’d have lost a lot of their energy by the time they reached us,” said LAT collaborator Luca Baldini of the Istituto Nazionale di Fisica Nucleare in Pisa, Italy.When combined with other recent results, the LAT finding provides compelling evidence ...
ASI Agenzia Spaziale Italiana 4 May 2009, 21:20 UTC On the 15th of June 2006 the PAMELA satellite-borne experiment was launched from the Baikonur cosmodrome and it is collecting data since July 2006. The core of the instrument is a silicon-microstrip magnetic spectrometer combined with a time-of-flight system, a silicon-tungsten electromagnetic calorimeter, a shower tail catcher scintillator, a neutron detector and an anticoincidence system. This telescope allows precision studies of the charged cosmic radiation to be conducted over a wide energy range (100 MeV - 100's GeV) with high statistics. Aim of this workshop is to provide an overview on the scientific issues, implications and perspectives in the field of Cosmic Ray Physics, Dark Matter and Solar Physics in the light of the recent results of PAMELA and other space and balloon missions, and in view of the planned future ones. The talks will cover presentations of the experimental results as well as theoretical and phenomenological interpretation and modelling. Correlations between Astroparticle and Particle Physics at accelerators (namely LHC) will also be reviewed.Scientists from different scientific communities will convene in the same place to discuss and debate - in a less formal way - on these very exciting topics and to give indications for the future: round tables are ...
