Astronomy Question Of The Week What Are Gravitational Lenses
Bonn, Germany (SPX) Jun 23, 2009
Ninety years ago, Arthur Eddington undertook an expedition to West Africa to confirm Albert Einstein's general theory of relativity. Eddington was not, of course, an ethnologist or geologist but an astrophysicist and he observed the solar eclipse there on 29 May 1919. This enabled him to photograph stars in the region around the Sun - stars which would otherwise have been obscured by the ... read more

Will Lisa Find Gravitational Waves And Prove Einstein Right
Bonn, Germany (SPX) Jun 09, 2009
Space and time are no longer what they used to be - absolute dimensions of the universe without regard to anything external. That is how Isaac Newton described them in the seventeenth century. In 1915, Albert Einstein completed his general theory of relativity, which fundamentally changed our view of space and time. The general theory of relativity deals with one of the basic physical ... more

  • GOCE Achieves Drag-Free Perfection
    Paris, France (SPX) May 27, 2009
    ESA's gravity mission GOCE has achieved a first in the history of satellite technology. The sophisticated electric propulsion system has shown that it is able to keep the satellite completely free from drag as it cuts through the remnants of Earth's atmosphere - paving the way for the best gravity data ever. Volker Liebig, ESA's Director of Earth Observation Programmes commented, "I am ver ... more

    QUIET Team To Deploy New Gravity-Wave Probe In June
    Chicago IL (SPX) May 18, 2009
    A tiny fraction of a second following the big bang, the universe allegedly experienced the most inflationary period it has ever known. During this inflationary era, space expanded faster than the speed of light. It sounds crazy, but it fits a variety of cosmological observations made in recent years, said University of Chicago physicist Bruce Winstein. "Theorists take it to be true ... more

    Einstein@Home Effort Launched To Search For New Pulsars
    Milwaukee WI (SPX) Mar 25, 2009
    Einstein@Home, based at the University of Wisconsin - Milwaukee (UWM) and the Albert Einstein Institute (AEI) in Germany, is one of the world's largest public volunteer distributed computing projects. More than 200,000 people have signed up for the project and donated time on their computers to search gravitational wave data for signals from unknown pulsars. Today, Prof. Bruce Allen, Direc ... more

    GOCE Completes Early Orbit Phase
    Paris, France (ESA) Mar 23, 2009
    ESA's GOCE satellite was formally declared ready for work at 01:00 CET on 20 March. During the critical Launch and Early Orbit Phase beginning with separation from its booster on 17 March, GOCE was checked out to confirm that all of its control systems are operating normally. The end of the Launch and Early Orbit Phase (LEOP) came overnight after GOCE was switched to Fine Pointing Mode. Th ... more

    GOCE Will Map The Earth's Gravity As Never Before
    Paris, France (SPX) Mar 10, 2009
    ESA is about to launch the most sophisticated of Earth Observation satellites to investigate the Earth's gravitational field with unprecedented resolution and accuracy. GOCE data will be crucial for obtaining accurate measurements of ocean circulation and sea-level change, both of which are affected by climate change. The data will help to better understand processes occurring inside the E ... more

    March Launch Planned For ESA's Gravity Mission
    Paris, France (SPX) Feb 05, 2009
    ESA is now gearing up to return to Russia to oversee preparations for the launch of its GOCE satellite - now envisaged for launch on 16 March 2009. This follows implementation of the corrective measures after the anomaly with the Rockot launcher that delayed the launch of GOCE by Eurockot Launch Services last October. An advance party from ESA has just arrived at the Plesetsk Cosmodrome in ... more

    NASA seeks microgravity flight test proposals
    Houston (UPI) Feb 2, 2009
    The U.S. space agency is seeking new technologies that could benefit from testing during flights on an airplane that simulates the weightlessness of space. The National Aeronautics and Space Administration said such technologies might improve air and space vehicle capabilities and support future systems used in space exploration. "To prepare technologies for space applications ... more

    Last-Ever Look At ESA Gravity Satellite GOCE
    Paris, France (ESA) Sep 05, 2008
    As preparations for the launch of GOCE on 10 September continue on schedule, an important milestone has just been achieved as engineers at the Plesetsk Cosmodrome in northern Russia say farewell to the satellite as it is encapsulated in the two half-shells of the launcher's fairing. Now sealing the slender five-metre long GOCE (Gravity field and steady-state Ocean Circulation Explorer) ... more
