Very Large Array Gets Expanded Capability

Active Seti points out a story about upgrades for the Very Large Array radio telescope. The improvements will increase the VLA's capabilities 10-fold, allowing it to "pick up a cell phone signal on Jupiter." Work on the 28-antenna array is already underway, and it is expected to finish by 2012. From Scientific American: "Data gathered by all 28 of the 82-foot- (25-meter-) diameter dish antennas are brought to a correlator--a central, special-purpose computer--which merges the input into a form that allows scientists to produce detailed, high-quality images of the astronomical objects under investigation. A new fiber-optic system replaces the older waveguide system for taking data collected by the receivers to the central control building and increases the amount of data that can be delivered from the antenna to the new $17-million correlator being built by Canadian scientists and engineers to handle the increased data flow."

    Is this new data provided to the SETI@Home folks, for them to process via their distributed processing network?

    Speaking of which, I've been meaning to run SETI@Home on my new PC, but my new PC tends to shutdown whenever I start the SETI@Home client. Then when I go to reboot my PC, it doesn't always start up. It'll "hesitate" for a second or two. Like, the fans will start to spin up and the case light will flicker, but it will then shut down again. Can anyone help me with this?

When driving, you come down off the mountains on any side of the basin, and it's a long, slow decline.

    The way I really understood how big the array was by seeing a picture of the A array, which has an antenna separation of 36 kilometers, overlayed on a city (I think it was Washington D.C.), at the visitor center. The antennas stretched beyond the boundaries of the city.

  42. Silver screen debut? by Aenoxi · · Score: 1

    TFA claims that the VLA's silver screen debut was in "Contact". But don't I remember seeing Heywood Floyd sitting on one at the start of the film "2010"?
    Or was that a different array?

    On another note, I drove to see the VLA in Socorro a year or so back. Absolutely awesome - in fact, so good that I just had to go to Hawaii to see the very long baseline array's western outlying dish. Now all I need to do is get to the eastern outlier in the Virgin Islands and I can send away for a free box of cornflakes :)
