An extraordinary time to be conducting SETI observations

Telescopes at SETI (Search for Extraterrestrial Life) are once again operational and searching planetary systems for signals of possible extraterrestrial intelligence. Great news I know, better still some of its first targets are the exoplanet candidates recently discovered by NASA’s Kepler space telescope.

SETI’s Alan Telescope Array (ATA) had been in hibernation since April following the withdrawal of the SETI Institute’s former partner, U.C. Berkeley – the operator of the observatory in California where the ATA is located – due to budgetary shortfalls (yawn yawn).

New funding has recently been acquired for observatory operations allowing the ATA to resume observations and work to examine the thousands of new candidate planets found by Kepler, with the highest priority given to the worlds discovered that are located in their star’s habitable zone.

Resuming observations was possible thanks to the interest and generosity of the public who supported the institute’s research via the SETI website with additional funds being provided by the United States Air Force as part of their formal assessment of the instrument’s utility for Space Situational Awareness.

From Jill Tarter, Director of SETI Research: We are exploring once again, with renewed enthusiasm.  While our work with the US Air Force to try to avoid future collisions in space will insure that the array is maintained in good operating condition, we will continue to have to raise the funds to conduct our SETI observations.

Awesome news! visit SETI here to find out more, donate too should you support the cause.

So HARPS releases news about 50 new exoplanets this week and soon after comes this!

NASA will announce a new discovery by its Kepler planet-hunting telescope on Thursday 15 September in a press conference featuring astronomers and — oddly — a representative from Industrial Light & Magic (ILM).

The announcement is scheduled for Thursday at 18:00 UTC/GMT and will broadcast and webcast live on NASA TV.

15 September. Just announced! Click here for the latest news and post.

The visual effects company, a division of Lucasfilm Ltd., was founded in 1975 by filmmaker George Lucas to produce the effects for his “Star Wars” films. ;)

HARPS discovers 50 new exoplanets

And there’s us thinking NASA’s Kepler telescope rules the roost over exoplanet hunting!

Today astronomers in La Silla, Chile announced a fertile haul of more than 50 new exoplanets – the latest results using ESO’s exoplanet hunter HARPS (High Accuracy Radial velocity Planet Searcher). The haul includes 16 super-Earths, one of which orbits at the edge of it’s habitable zone around its star. By studying the properties of the planets found so far, the ESO team have discovered that around 40% of stars similar to our Sun have at least one planet lighter than Saturn.

Lead author Dr Michel Mayor, from the University of Geneva in Switzerland, said the haul included “an exceptionally rich population of super-Earths and Neptune-type planets hosted by stars very similar to our Sun”.

He added: “The new results show that the pace of discovery is accelerating.”

One of the recently announced newly discovered planets, HD 85512 b, is estimated to be only 3.6 times the mass of the Earth and is located at the edge of the habitable zone.

“This is the lowest-mass confirmed planet discovered by the radial velocity method that potentially lies in the habitable zone of its star, and the second low-mass planet discovered by HARPS inside the habitable zone,” says Lisa Kaltenegger (Max Planck Institute for Astronomy, Heidelberg, Germany and Harvard Smithsonian Center for Astrophysics, Boston, USA), who is an expert on exoplanets habitability.

Astronomers are confident they are close to discovering other small and rocky habitable planets around stars similar to our Sun. Moving forward new instruments are planned to further the search and include a copy of HARPS to be installed on the Telescopio Nazionale Galileo in the Canary Islands, to survey stars in the northern sky, as well as a new and more powerful planet-finder, ESPRESSO, to be installed on ESO’s Very Large Telescope in 2016. Looking further into the future the planned CODEX instrument on the European Extremely Large Telescope (E-ELT) will push this technique to a higher level.

Wouldn’t it be great to wake up one morning to a fresh Sky-Watching post actually detailing a habitable planet! I guess by then we could just beam the information directly to your brain! ;)

Yay yay – the Allen Telescope Array!

Telescopes looking for extra terrestrial intelligence should re-open within weeks after donors replaced income lost in public funding cuts.

The Search for Extraterrestrial Intelligence (SETI) Institute, had to shut the £18m Allen Telescope Array in April but donors have since raised more than £120,000 with more than 2,400 people contributing to the fund. Donors include the likes of actress Jodie Foster who played the lead role of an astronomer looking for evidence of aliens in the 1997 film Contact. Amongst other donors was the Apollo 8 astronaut, Bill Anders.

The 42 radio telescopes, in northern California, search space for potential signals from alien life forms.

The SETI Institute says the fund should be enough to keep the telescopes operating until the end of 2011.  The plan is still dependent on the institute receiving money from the US Air Force to help track space debris that could damage satellites.

SETI is hoping to raise more money to contribute to the £1.5m annual operating and staffing costs of the telescopes and keep them going beyond the end of this year. Ultimately the plan is to use the array to observe planets outside our own Solar System.

The array also contributes to research into black holes, pulsars and magnetic fields in the Milky Way.
