Astronomer announces shortlist of stellar candidates for habitable worlds
EurekaAlert ^ | 02/18/06 | Earl Lane

Posted on 02/18/2006 1:26:06 PM PST by KevinDavis

In the search for life on other worlds, scientists can listen for radio transmissions from stellar neighborhoods where intelligent civilizations might lurk or they can try to actually spot planets like our own in habitable zones around nearby stars. Either approach is tricky and relies on choosing the right targets for scrutiny out of the many thousands of nearby stars in our galactic neighborhood.

Margaret Turnbull, an astronomer at the Carnegie Institution of Washington, has devoted herself to the painstaking search for candidate stars that may harbor zones of habitability where life--primitive or otherwise-- might thrive. Turnbull announced her shortlist of so-called "habstars" at the 2006 Annual Meeting of the American Association for the Advancement of Science in St. Louis.

Out of an initial catalogue of 17,129 "habitable stellar systems" that Turnbull and her colleagues published in 2003, she selected a handful of stars that she considers her best bets, based on a variety of screening criteria.

Turnbull offered five top candidate stars for those seeking only to listen for radio signals from intelligent civilizations--the Search for Extraterrestrial Intelligence or SETI--and five candidates for those who undertake the demanding job of trying to detect Earth-like planets in orbit around nearby stars.

The big question is: do they have Stargates so that we can reach them? ;-)

If they do all I ask is that the inhabitants

a) don't have snakes in their bodies
b) worship a interstellar version of Islam
c) overun by a bunch of mechanical bugs...

"If a prior visits your world, leave."

Amend it with, "If a Democrat visits your world, leave."

Profile: Margaret Turnbull
Margaret Turnbull's career has included construction, setup, testing and repair of detectors and readout system for an Antarctic Muon and Neutrino detector array.

At the University of Wisconsin in space physics, payload construction, she was involved in detector preparation for the X-ray Quantum Calorimeter sub-orbital launch experiment.

At Lowell Observatory in Arizona, she participated in the examination of main-belt and Earth-crossing asteroid orbital parameters and trends of ephemeris uncertainty with orbital parameters.

She has done Monte Carlo modeling of high-resolution Hubble Space Telescope images of protostars in the Taurus-Auriga dark cloud at the Harvard-Smithsonian Astrophysical Observatory. And in the radio domain, she has analyzed large-scale HI 21 cm emission from Seyfert galaxies imaged by the Very Large Array, and conducted a search for obvious distortions caused by unseen companion galaxies.

The more fundamental question: Do they have radio? It is possible to imagine a human history in which it is not developed. Left to follow its trajectory, Chinese civilization would never have invented it.

No good can come of this.

I was wondering if there were some correlation between Islam and Origin... We will know if priors start blowing themselves up... Oh, wait, one did that already.

I think the writers were going for a link between Origin and the Spanish Inquisition.

Islamic extremists aren't saying, "Convert or die!" They're saying, "Die infidel!"
