No one ever demonstrated, so far as I am aware, the nonexistence of Zeus or Thor, but they have few followers now." - Arthur C. Clarke in Childhood's End http://www.2think.org/ce.shtml Of course I recognize that one big reason Zeus and Thor and the rest of their pantheon have few followers these days is because they were supplanted by another pantheon of deities starting about two thousand years ago. Science and reason are being threatened at every turn these days. Now certain groups are trying to use the very things they rejected as warped tools against the things that keep barbarity and totalitarianism at bay. Science itself may remain aloof from such matters in order to stick to its tenents of objectivity, but I don't think scientists can do the same, for the sake of the discipline. The question is, are the so-called science leaders and the rest up to the task? The first thing they better understand is that those who promote ID and those who follow will not using their own brands of logic and understanding, with a heavy dose of emotionalism added for good measure. And remember something else: You can't just "take away" these people's beliefs and leave them with nothing in their place, no matter what the truth is. People have the right to believe what they want, especially those who would probably collapse in a reality where there is no benevolent Father/Mother Figure watching over them. What we are defending here is to make sure that science and reason do not get plowed under by those on the other side who do not play by the fairness and equality rules. This recent news has simply reassured me that SETI and its success is more important than ever these days. Otherwise we will revert back to a world controlled by a theocracy where everyone thinks that the whole Universe circles Earth, if they even think that far. If you don't think that can happen, just look at the Islamic world, which once had the highest of sciences and culture until the fundamentalist religious leaders suppressed their works and ideas. "One of the saddest lessons of history is this: If we've been bamboozled long enough, we tend to reject any evidence of the bamboozle. We're no longer interested in finding out the truth... It's simply too painful to acknowledge, even to ourselves, that we've been taken." - Carl Sagan "I'm a seeker too. But my dreams aren't like yours. I can't help thinking that somewhere in the universe there has to be something better than man. Has to be." - Taylor (Charlton Heston), Planet of the Apes (1968) http://en.wikipedia.org/wiki/Planet_of_the_Apes_%281968_film%29 From owner-public@setileague.org Wed Oct 5 18:41:17 2005 Received: from seti1.setileague.org (seti1.setileague.org [204.176.91.10]) by Sentry.net (8.13.3/8.13.3) with ESMTP id j95IfGqw021381 for ; Wed, 5 Oct 2005 18:41:16 GMT Received: (from majordom@localhost) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) id OAA05538 for public-list; Wed, 5 Oct 2005 14:35:30 -0400 (EDT) X-Authentication-Warning: seti1.setileague.org: majordom set sender to owner-public@seti1.setileague.org using -f Received: from hotmail.com (bay103-f23.bay103.hotmail.com [65.54.174.33]) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) with ESMTP id OAA05534; Wed, 5 Oct 2005 14:35:27 -0400 (EDT) Received: from mail pickup service by hotmail.com with Microsoft SMTPSVC; Wed, 5 Oct 2005 11:34:55 -0700 Message-ID: Received: from 65.54.174.200 by by103fd.bay103.hotmail.msn.com with HTTP; Wed, 05 Oct 2005 18:34:54 GMT X-Originating-IP: [24.39.94.195] X-Originating-Email: [ljk4@msn.com] X-Sender: ljk4@msn.com From: "LARRY KLAES" To: public@setileague.org Cc: bioastro@setileague.org Subject: SETI public: Test Equipment Finds Life in Mars-like Conditions Date: Wed, 05 Oct 2005 14:34:54 -0400 Mime-Version: 1.0 Content-Type: text/plain; format=flowed X-OriginalArrivalTime: 05 Oct 2005 18:34:55.0821 (UTC) FILETIME=[7B9377D0:01C5C9DB] Sender: owner-public@setileague.org Precedence: bulk X-Spam-Checker-Version: SpamAssassin 3.0.4 (2005-06-05) on Sentry.net X-Spam-Level: X-Spam-Status: No, score=0.0 required=5.5 tests=MSGID_FROM_MTA_HEADER autolearn=failed version=3.0.4 Science/Astronomy: * Test Equipment Finds Life in Mars-like Conditions http://www.space.com/scienceastronomy/051004_mars_like.html In a test of equipment that might one day be used to search for biological activity on Mars, researchers discovered life tucked deep inside a frozen Norwegian volcano.

The dynamo process is of alpha^2 type and thus differs from the shell-dynamo at work in more massive stars.The alpha^2 dynamo becomes supercritical for Rossby numbers Ro\la 10. It generates a large-scale, non-axisymmetric, steady field that is symmetric with respect to the equatorial plane. Saturation of the alpha^2-generated field at the equipartition yields strengths of several kGauss, in agreement with observations of active M dwarfs, and provides a qualitative explanation for the observed activity saturation in late M stars. For brown dwarfs with a conductive core, as occurs at the center of the most massive and oldest of these objects, we have also studied an alpha^2-Omega dynamo, i.e. the effect of differential rotation. In this case the field is predominantly toroidal, axisymmetric and oscillatory, like the solar field. The topology of the field in the fully convective objects exhibits a high order multipole character that differs from the aligned dipole field generated by the alpha-Omega dynamo. The strong reduction of the dipolar component due to the field non-axisymmetry should considerably reduce the Alfven radius and thus the efficiency of magnetic braking, providing an appealing explanation for the decreasing angular momentum loss rate observed in low-mass stars and brown dwarfs. This may have also implications for cataclysmic variables below the period gap. In spite of this large-scale field, the decreasing conductivity in the dominantly neutral atmosphere of these objects prevents the current generation necessary to support a chromosphere and thus activity.

Saffe, M. Gomez, C. Chavero Categories: astro-ph Comments: 22 pages, 25 figures, A&A accepted \\ We obtained spectra, covering the CaII H and K region, for 49 exoplanet host (EH) stars, observable from the southern hemisphere. We measured the chromospheric activity index, Rhk. We compiled previously published values of this index for the observed objects as well as the remaining EH stars in an effort to better smooth temporal variations and derive a more representative value of the average chromospheric activity for each object. We used the average index to obtain ages for the group of EH stars. In addition we applied other methods, such as: Isochrone, lithium abundance, metallicity and transverse velocity dispersions, to compare with the chromospheric results. The kinematic method is a less reliable age estimator because EH stars lie red-ward of Parenago's discontinuity in the transverse velocity dispersion vs dereddened B-V diagram. The chromospheric and isochrone techniques give median ages of 5.2 and 7.4 Gyr, respectively, with a dispersion of 4 Gyr. The median age of F and G EH stars derived by the isochrone technique is 1--2 Gyr older than that of identical spectral type nearby stars not known to be associated with planets. However, the dispersion in both cases is large, about 2--4 Gyr. We searched for correlations between the chromospheric and isochrone ages and Lir/L* (the excess over the stellar luminosity) and the metallicity of the EH stars. No clear tendency is found in the first case, whereas the metallicy dispersion seems to slightly increase with age. \\ ( http://arXiv.org/abs/astro-ph/0510092 , 133kb) From owner-public@setileague.org Thu Oct 6 09:21:03 2005 Received: from seti1.setileague.org (seti1.setileague.org [204.176.91.10]) by Sentry.net (8.13.3/8.13.3) with ESMTP id j96GL2pY028633 for ; Thu, 6 Oct 2005 16:21:03 GMT Received: (from majordom@localhost) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) id MAA09685 for public-list; Thu, 6 Oct 2005 12:13:31 -0400 (EDT) X-Authentication-Warning: seti1.setileague.org: majordom set sender to owner-public@seti1.setileague.org using -f Received: from hotmail.com (bay103-f24.bay103.hotmail.com [65.54.174.34]) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) with ESMTP id MAA09681; Thu, 6 Oct 2005 12:13:29 -0400 (EDT) Received: from mail pickup service by hotmail.com with Microsoft SMTPSVC; Thu, 6 Oct 2005 09:12:57 -0700 Message-ID: Received: from 65.54.174.200 by by103fd.bay103.hotmail.msn.com with HTTP; Thu, 06 Oct 2005 16:12:56 GMT X-Originating-IP: [24.39.94.195] X-Originating-Email: [ljk4@msn.com] X-Sender: ljk4@msn.com From: "LARRY KLAES" To: public@setileague.org Cc: bioastro@setileague.org Subject: SETI public: Trojan pairs in the HD 128311 and HD 82943 planetary systems?

Authors: Krzysztof Gozdziewski, Maciej Konacki Categories: astro-ph Comments: 10 pages (total), 9 figures, submitted to ApJ Two nearby stars, HD 128311 and HD 82943, are believed to host pairs of Jupiter-like planets involved in a strong first order 2:1 mean motion resonance. In this work we reanalyze available radial velocity (RV) measurements and demonstrate that it is also possible to explain the observed RV variations of the parents stars as being induced by a pair of Trojan planets. We show that these Trojan configurations reside in extended zones of stability in which such systems may easily survive in spite of large masses of the planets, large eccentricities and nonzero mutual inclinations of their orbits. http://arxiv.org/abs/astro-ph/0510109 From owner-public@setileague.org Thu Oct 6 09:25:19 2005 Received: from seti1.setileague.org (seti1.setileague.org [204.176.91.10]) by Sentry.net (8.13.3/8.13.3) with ESMTP id j96GPI6c029127 for ; Thu, 6 Oct 2005 16:25:19 GMT Received: (from majordom@localhost) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) id MAA09854 for public-list; Thu, 6 Oct 2005 12:19:41 -0400 (EDT) X-Authentication-Warning: seti1.setileague.org: majordom set sender to owner-public@seti1.setileague.org using -f Received: from hotmail.com (bay103-f1.bay103.hotmail.com [65.54.174.11]) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) with ESMTP id MAA09848; Thu, 6 Oct 2005 12:19:39 -0400 (EDT) Received: from mail pickup service by hotmail.com with Microsoft SMTPSVC; Thu, 6 Oct 2005 09:19:08 -0700 Message-ID: Received: from 65.54.174.200 by by103fd.bay103.hotmail.msn.com with HTTP; Thu, 06 Oct 2005 16:19:07 GMT X-Originating-IP: [24.39.94.195] X-Originating-Email: [ljk4@msn.com] X-Sender: ljk4@msn.com From: "LARRY KLAES" To: public@setileague.org Cc: bioastro@setileague.org Subject: SETI public: ELODIE metallicity-biased search for transiting Hot Jupiters II.

A very hot Jupiter transiting the bright K star HD189733 Authors: Francois Bouchy (LAM, OHP), Stephane Udry, Michel Mayor, Claire Moutou (LAM), Frederic Pont, Nicolas Iribarne (OHP), Ronaldo Da Silva, Sergio Ilovaisky (OHP), Didier Queloz, Nuno Santos, Damien Segransan, Shay Zucker Categories: astro-ph Comments: 5 pages, submitted to Astronomy & Astrophysics Among the 160 known exoplanets, mainly detected in large radial-velocity surveys, only 8 have a characterization of their actual mass and radius thanks to the two complementary methods of detection: radial velocities and photometric transit. We started in March 2004 an exoplanet-search programme biased toward high-metallicity stars which are more frequently host extra-solar planets. This survey aims to detect close-in giant planets, which are most likely to transit their host star. For this programme, high-precision radial velocities are measured with the ELODIE fiber-fed spectrograph on the 1.93-m telescope, and high-precision photometry is obtained with the CCD Camera on the 1.20-m telescope, both at the Haute-Provence Observatory. We report here the discovery of a new transiting hot Jupiter orbiting the star HD189733. The planetary nature of this object is confirmed by the observation of both the spectroscopic and photometric transits. The exoplanet HD189733b, with an orbital period of 2.219 days, has one of the shortest orbital periods detected by radial velocities, and presents the largest photometric depth in the light curve (~ 3%) observed to date. We estimate for the planet a mass of 1.15 +- 0.04 Mjup and a radius of 1.26 +- 0.03 RJup. Considering that HD189733 has the same visual magnitude as the well known exoplanet host star HD209458, further ground-based and space-based follow-up observations are very promising and will permit a characterization of the atmosphere and exosphere of this giant exoplanet. http://arxiv.org/abs/astro-ph/0510119 From owner-public@setileague.org Thu Oct 6 09:32:00 2005 Received: from seti1.setileague.org (seti1.setileague.org [204.176.91.10]) by Sentry.net (8.13.3/8.13.3) with ESMTP id j96GVxVb029947 for ; Thu, 6 Oct 2005 16:31:59 GMT Received: (from majordom@localhost) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) id MAA10028 for public-list; Thu, 6 Oct 2005 12:24:43 -0400 (EDT) X-Authentication-Warning: seti1.setileague.org: majordom set sender to owner-public@seti1.setileague.org using -f Received: from hotmail.com (bay103-f17.bay103.hotmail.com [65.54.174.27]) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) with ESMTP id MAA10024; Thu, 6 Oct 2005 12:24:41 -0400 (EDT) Received: from mail pickup service by hotmail.com with Microsoft SMTPSVC; Thu, 6 Oct 2005 09:24:10 -0700 Message-ID: Received: from 65.54.174.200 by by103fd.bay103.hotmail.msn.com with HTTP; Thu, 06 Oct 2005 16:24:09 GMT X-Originating-IP: [24.39.94.195] X-Originating-Email: [ljk4@msn.com] X-Sender: ljk4@msn.com From: "LARRY KLAES" To: public@setileague.org Cc: bioastro@setileague.org Subject: SETI public: Detection of Six Transneptunian Binaries with NICMOS: A High Fraction of Binarie Date: Thu, 06 Oct 2005 12:24:09 -0400 Mime-Version: 1.0 Content-Type: text/plain; format=flowed X-OriginalArrivalTime: 06 Oct 2005 16:24:10.0581 (UTC) FILETIME=[61DC9850:01C5CA92] Sender: owner-public@setileague.org Precedence: bulk X-Spam-Checker-Version: SpamAssassin 3.0.4 (2005-06-05) on Sentry.net X-Spam-Level: X-Spam-Status: No, score=0.0 required=5.5 tests=MSGID_FROM_MTA_HEADER autolearn=failed version=3.0.4 astro-ph/0510130 [abs, ps, pdf, other] : Title: Detection of Six Transneptunian Binaries with NICMOS: A High Fraction of Binaries in the Cold Classical Disk Authors: D. C. Stephens, K. S. Noll Categories: astro-ph Comments: Accepted for Publication in the Astronomical Journal, 24 pages We have analyzed a homogeneous set of observations of eighty-one transneptunian objects obtained with the NIC2 camera on the Hubble Space Telescope with the goal of identifying partially resolved binaries. Using PSF-fitting we have identified six likely binaries in addition to the three new binaries already found in this data set. We find that 11% of transneptunian objects are binaries at separation and brightness limits of the NIC2 camera. The identification of these new binaries significantly increases the known lower limit to the binary fraction among transneptunian objects. The origin of such a high fraction of binaries remains to be determined. Most interestingly, detectable binaries appear to be about four times more common among the cold classical disk than in the dynamically excited populations. http://arxiv.org/abs/astro-ph/0510130 From owner-public@setileague.org Thu Oct 6 15:54:12 2005 Received: from seti1.setileague.org (seti1.setileague.org [204.176.91.10]) by Sentry.net (8.13.3/8.13.3) with ESMTP id j96MsCA2001193 for ; Thu, 6 Oct 2005 22:54:12 GMT Received: (from majordom@localhost) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) id SAA20424 for public-list; Thu, 6 Oct 2005 18:48:36 -0400 (EDT) X-Authentication-Warning: seti1.setileague.org: majordom set sender to owner-public@seti1.setileague.org using -f Received: from hotmail.com (bay103-dav7.bay103.hotmail.com [65.54.174.79]) by seti1.setileague.org (8.9.3 (PHNE_24419+JAGae58098)/8.9.3) with ESMTP id SAA20420; Thu, 6 Oct 2005 18:48:33 -0400 (EDT) Received: from mail pickup service by hotmail.com with Microsoft SMTPSVC; Thu, 6 Oct 2005 15:48:02 -0700 Message-ID: Received: from 129.44.237.74 by BAY103-DAV7.phx.gbl with DAV; Thu, 06 Oct 2005 22:48:01 +0000 X-Originating-IP: [129.44.237.74] X-Originating-Email: [ljk4@msn.com] X-Sender: ljk4@msn.com From: "LARRY KLAES" To: "setipublic" Cc: "BioAstro" Subject: SETI public: Cranking Up the Allen Telescope Array Date: Thu, 6 Oct 2005 18:48:02 -0400 MIME-Version: 1.0 Content-Type: multipart/alternative; boundary="----=_NextPart_000_0058_01C5CAA6.7B173EB0" X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: MSN 9 X-MimeOLE: Produced By MSN MimeOLE V9.10.0011.1703 Seal-Send-Time: Thu, 6 Oct 2005 18:48:02 -0400 X-OriginalArrivalTime: 06 Oct 2005 22:48:02.0324 (UTC) FILETIME=[01D9AD40:01C5CAC8] Sender: owner-public@setileague.org Precedence: bulk X-Spam-Checker-Version: SpamAssassin 3.0.4 (2005-06-05) on Sentry.net X-Spam-Level: X-Spam-Status: No, score=0.0 required=5.5 tests=HTML_MESSAGE, MSGID_FROM_MTA_HEADER autolearn=failed version=3.0.4 This is a multi-part message in MIME format. ------=_NextPart_000_0058_01C5CAA6.7B173EB0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable Science/Astronomy: * Cranking Up the Allen Telescope Array http://www.space.com/searchforlife/seti_igps_one_051006.html= Three dozen metal mushrooms have sprouted near the modest village of Hat = Creek, and are turning their aluminum eyes skyward. ------=_NextPart_000_0058_01C5CAA6.7B173EB0 Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable
