Telescopes can tune in to alien TV

10-25-2006 · EurekAlert!

Radio telescopes designed to study the early universe could be sensitive enough to pick-up radio leakage from alien civilizations. Researchers from Harvard University say that the most powerful emissions from our own planet come from military radar, TV and FM radio transmitters. If ET is producing similar signals, these spikes in the radio spectrum could be detected by telescopes being built today

  1. The planet, the galaxy and the laser
    08-03-2007 · EurekAlert!
    On the night of July 21, ESO astronomer Yuri Beletsky took images of the night sky above Paranal, the 2600-meter high mountain in the Chilean Atacama Desert home to ESO's Very Large Telescope. The amazing images bear witness to the unique quality of the sky, revealing not only the Milky Way in all its splendour but also the planet Jupiter and the laser beam used at Yepun, one of the 8.2-meter telescopes that make up this extraordinary facility.

  2. First astrophysical results with AMBER/VLTI
    02-21-2007 · EurekAlert!
    The AMBER instrument installed at the Very Large Telescope (VLT) of the European Southern Observatory (ESO) combines the light from three 8.2 meter telescopes, making the VLT the world's largest optical telescope, with a total mirror surface larger than 150 m2 and a maximum telescope separation greater than 130 m. Two years after installation, the first astrophysical results are blossoming. They are being published this week as a special feature in Astronomy & Astrophysics.

  3. The impossible siblings
    03-29-2007 · EurekAlert!
    Combining precise observations obtained by ESO's Very Large Telescope with those gathered by a network of smaller telescopes, astronomers have described in unprecedented detail the double asteroid Antiope, which is shown to be a pair of rubble-pile chunks of material, of about the same size, whirling around one another in a perpetual pas de deux. The two components are egg-shaped despite their very small sizes.

  4. New Adaptive Optics technique demonstrated
    03-30-2007 · EurekAlert!
    On the evening of 25 March 2007, the Multi-Conjugate Adaptive Optics Demonstrator (MAD) achieved First Light at the Visitor Focus of Melipal, the third Unit Telescope of the Very Large Telescope (VLT). MAD allowed the scientists to obtain images corrected for the blurring effect of atmospheric turbulence over the full 2x2 arcminute field of view. This world premiere shows the promises of a crucial technology for Extremely Large Telescopes.

  5. Edge-on!
    08-23-2007 · EurekAlert!
    As Uranus coasts through a brief window of time when its rings are edge-on to Earth -- a view of the planet we get only once every 42 years -- astronomers peering at the rings with ESO's Very Large Telescope and other space or ground-based telescopes are getting an unprecedented view of the fine dust in the system, free from the glare of the bright rocky rings. They may even find a new moon or two.

  6. Giant planets do not come as lonely hearts
    02-14-2008 · EurekAlert!
    Scaled versions of Jupiter and Saturn orbiting a star 5000 light-years away, half as massive as the sun, have been revealed from an effort involving a world-wide net of telescopes, including the UK's Liverpool Telescope on the Canary Islands. This marks the first discovery of another system of planets that has striking similarities with our solar system.

  7. Hubble sees 'Comet Galaxy' being ripped apart by galaxy cluster
    03-02-2007 · EurekAlert!
    The NASA/ESA Hubble Space Telescope, in collaboration with several other ground- and space-based telescopes, has captured a galaxy being ripped apart by a galaxy cluster's gravitational field and harsh environment. The finding sheds light on the mysterious process by which gas-rich spiral-shaped galaxies might evolve into gas-poor irregular- or elliptical-shaped galaxies over billions of years. The new observations also show one mechanism to form the millions of "homeless" stars seen scattered throughout galaxy clusters.

  8. Hubble and Spitzer Space Telescopes find 'Lego-block' galaxies in early universe
    09-06-2007 · EurekAlert!
    The NASA/ESA Hubble Space Telescope and the NASA Spitzer Space Telescope have joined forces to discover nine of the smallest, faintest, most compact galaxies ever observed in the distant universe. Blazing with the brilliance of millions of stars, each of the newly discovered galaxies is a 100 to 1,000 times smaller than our Milky Way Galaxy.

  9. SETI@home ramps up to analyze more data in search of extraterrestrial intelligence
    01-02-2008 · EurekAlert!
    The longest-running search for radio signals from alien civilizations is getting a burst of new data from an upgraded Arecibo telescope, which means the SETI@home project needs more desktop computers to help crunch the data. According to UC Berkeley's Dan Werthimer, the project already boasts the largest number of dedicated users: 170,000.
