SETI suspended:
Aliens, call back later
The SETI Institute is suspending its search for extraterrestrial
radio beacons using its most advanced alien signal-seeking tool while it
hunts for new sources of funding.
ET, we’re not listening. |
The privately financed group, based in Mountain View, California, has
been using an array of radio telescopes at Hat Creek Observatory, about
300 miles north of San Francisco, since October 2007, to study stars for
non-naturally occurring radio signals that could indicate the presence
of a technologically advanced civilization beyond Earth.
Microsoft co-founder Paul Allen provided an initial $25 million for
the project, which is known as the Allen Telescope Array. The network
eventually is intended to have 350 telescopes. The University of
California at Berkeley, the National Science Foundation and several
corporate and individual donors provided operating funds.
Budget cutbacks by the state of California and the NSF, however, have
hit the project hard. Not only was the expansion postponed, now the
search for ET itself is on hold. In a blog post on Friday, astronomer
Franck Marchis, who is not involved in SETI research but who works at
institutes that are, disclosed that operations of the Allen Telescope
Array have been suspended.
In addition to SETI work, the observatory shutdown impacts mainstream
radio astronomy projects, such as a survey of extragalactic radio
sources. There is a light at the end of the tunnel, however. Since 2009,
writes Marchis, the Air Force has been looking at using the Allen
Telescope Array to keep track of orbital debris whizzing around the
planet.
Marchis writes: 'The future of the ATA may depend of the US Air Force
program. Unfortunately, because of the recent federal finance turmoil,
no clear decision has been taken with enough time to keep the
observatory running. Since April 15, the observatory is in hibernation.
All the equipments have been taken care of to make sure that they do not
deteriorate over time.
