Two hundred and fifty-one million years old, to be precise. But the story of what happened then, which has now been told for the first time, demands our urgent attention.

Unless we understand what happened, and act upon that intelligence, prehistory may very soon repeat itself, not as tragedy, but as catastrophe. =20 The events that brought the Permian period (between 286m and 251m years ago) to an end could not be clearly determined until the mapping of the key geological sequences had been completed. Until recently, palaeontologists had assumed that the changes that took place then were gradual and piecemeal. But three years ago a precise date for the end of the period was established, which enabled geologists to draw direct comparisons between the rocks laid down at that time in different parts of the world. =20 Having done so, they made a shattering discovery. In China, South Africa, Australia, Greenland, Russia and Svalbard, the rocks record an almost identical sequence of events, taking place not gradually, but relatively instantaneously. They show that a cataclysm caused by natural processes almost brought life on earth to an end. They also suggest that a set of human activities that threatens to replicate those processes could exert the same effect, within the lifetimes of some of those who are on earth today. =20 As the professor of palaeontology Michael Benton records in his new book, When Life Nearly Died, the marine sediments deposited at the end of the Permian period record two sudden changes. The first is that the red or green or grey rock laid down in the presence of oxygen is suddenly replaced by black muds of the kind deposited when oxygen is absent. At the same time, an instant shift in the ratio of the isotopes (alternative forms) of carbon within the rocks suggests a spectacular change in the concentration of atmospheric gases. =20 On land, another dramatic transition has been dated to precisely the same time. In Russia and South Africa, gently deposited mudstones and limestones suddenly give way to massive dumps of pebbles and boulders. But the geological changes are minor in comparison with what happened to the animals and plants. =20 The Permian was one of the most biologically diverse periods in the earth's history. Herbivorous reptiles the size of rhinos were hunted through forests of tree ferns and flowering trees by sabre-toothed predators. At sea, massive coral reefs accumulated, among which lived great sharks, fish of all kinds and hundreds of species of shell creatures. =20 Then suddenly there is almost nothing. The fossil record very nearly stops dead. The reefs die instantly, and do not reappear on earth for 10 million years. All the large and medium-sized sharks disappear, most of the shell species, and even the great majority of the toughest and most numerous organisms in the sea, the plankton. Among many classes of marine animals, the only survivors were those adapted to the near-absence of oxygen. =20 On land, the shift was even more severe. Plant life was almost eliminated from the earth's surface. The four-footed animals, the category to which humans belong, were nearly exterminated: so far only two fossil reptile species have been found anywhere on earth that survived the end of the Permian. The world's surface came to be dominated by just one of these, an animal a bit like a pig. It became ubiquitous because nothing else was left to compete with it or to prey upon it. =20 Altogether, Benton shows, some 90% of the earth's species appear to have been wiped out: this represents by far the gravest of the mass extinctions. The world's "productivity" (the total mass of biological matter) collapsed. =20 Ecosystems recovered very slowly. No coral reefs have been found anywhere on earth in the rocks laid down over the following 10 million years. One hundred and fifty million years elapsed before the world once again became as biodiverse as in the Permian. =20 So what happened? Some scientists have argued that the mass extinction was caused by a meteorite. But the evidence they put forward has been undermined by further studies. There is a more persuasive case for a different explanation. For many years, geologists have been aware that at some point during or after the Permian there was a series of gigantic volcanic eruptions in Siberia. The lava was dated properly for the first time in the early 1990s. We now know that the principal explosions took place 251 million years ago, precisely at the point at which life was almost extinguished. =20 The volcanoes produced two gases: sulphur dioxide and carbon dioxide. The sulphur and other effusions caused acid rain, but would have bled from the atmosphere quite quickly. The carbon dioxide, on the other hand, would have persisted. By enhancing the greenhouse effect, it appears to have warmed the world sufficiently to have destabilised the superconcentrated frozen gas called methane hydrate, locked in sediments around the polar seas. The release of methane into the atmosphere explains the sudden shift in carbon isotopes. =20 Methane is an even more powerful greenhouse gas than carbon dioxide. The result of its release was runaway global warming: a rise in temperature led to changes that raised the temperature further, and so on. The warming appears, alongside the acid rain, to have killed the plants. Starvation then killed the animals. =20 Global warming also seems to explain the geological changes. If the temperature of the surface waters near the poles increases, the circulation of marine currents slows down, which means that the ocean floor is deprived of oxygen. As the plants on land died, their roots would cease to hold together the soil and loose rock, with the result that erosion rates would have greatly increased. =20 So how much warming took place? A sharp change in the ratio of the isotopes of oxygen permits us to reply with some precision: 6C. Benton does not make the obvious point, but another author, the climate change specialist Mark Lynas, does. Six degrees is the upper estimate produced by the UN's scientific body, the intergovernmental panel on climate change (IPCC), for global warming by 2100. A conference of some of the world's leading atmospheric scientists in Berlin last month concluded that the IPCC's model may have underestimated the problem: the upper limit, they now suggest, should range between 7 and 10 degrees. Neither model takes into account the possibility of a partial melting of the methane hydrate still present in vast quantities around the fringes of the polar seas. =20 Suddenly, the events of a quarter of a billion years ago begin to look very topical indeed.

It is old news, I admit.= Two hundred and fifty-one million years old, to

I'm interested to know what motivates the set of wavelengths chosen for Radio Astronomy (2cm, 3, 6, 13, 20, 21 - right?) and how this relates to the frequencies of interest to astronomers (see Hans Brakob's list - reached by searching the SETILeague's files). My underlying concern is to work through the two sets of figures to find frequencies other than Hydrogen which might be significant. Could someone enlighten me? Are RA wavelengths other than those listed above blocked by atmospheric or physical or parochial/social factors?

The electromagnetic spectrum is a valuable and finite resource. Commercial applications have pretty much staked out all available wavelengths, producing a level of RF pollution that makes radio astronomy difficult if not impossible in many locations. Radio astronomers fight (usually unsuccessfully) to protect the most crucial areas of the spectrum from encroachment. Hans' list shows the few very narrow protected segments left. There would be other, equally good areas of the spectrum to conduct SETI observations, but for Earth's technology making them unusable. This is why the IAA Cosmic Study to put a radio telescope on lunar farside is far more than science fiction, but a very important scientific reality (lacking only funding). -------------------------------- H.

Atmospheric conditions may extend the lower wavelength to as much as 30 m or more. I think Grote Reber, before his passing, worked at 160 meters. Hope this helps (hope I'm right).

After some contemplation of your response I offer the following. I am not likely to every be a member of the SETI League, your direction and focus is of keen interest but like you I have learned that one has to focus to achieve things, and my focus is elsewhere. I am specifically into research on LDE's and within the same general problem the achievement of a two way QSO across the North Atlantic on 144 MHz. I have completed the QSO across the North Atlantic on 136 KHz already. The SETI League ARGUS list just might produce some cross fertilization in both directions from my work here and I would like to stimulate that. In the interest of science and amateur radio I suggest it would be in your interest to stimulate the ARGUS list discussion about my inquiry. There are many ways to stimulate progress in the many areas of interest - limiting discussion to only those within a group, such as SETI League I offer, is not in your best interest or mine. A while back, I made a careful review of the software and resources available in the SETI League - I was dismayed to find that much of the material was seriously out of date and that much of the material had not been updated in a period of many months to years - not a strong proposition to stimulate membership by someone who is working in a rather distant and fringe area. As I remember you were advertising for someone to work on the whole issue of Pattern Recognition software for the SETI League interests at that time. I can assure you that I will solve the problem, the only issue is how much effort do I have to put in to do it - effort directly relates to time in my case. All this being said, please consider forwarding my inquiry to your ARGUS list. When I have resolved the issue of a Pattern Recognition process for propagation studies I can assure you that the results will eventually be available to the SETI League as well as everyone else. The time is now to go beyond the common DSP tools that are Terminal based and enter the next steps of qualifying the data as being of SOME or NO interest before using them. I hope we can have some information sharing and development.

The SETI League certainly supports information sharing, Larry. That is why we sponsor (at our dues-paying members' expense) two open email lists, and an extensive (and rather expensive) website. But, The SETI League has been running a $50,000 US per year deficit for the past two years, and has VERY FINITE resources. Since September 2001 donations (our sole source of operating funds) are down an alarming 90%. Thus it is not in the best interest of our loyal members in good standing to open up all of our forums to hams not willing or able to contribute to our financial needs. This is the reality: if people like you don't join, for whatever valid reason, we will simply cease to exist, and then there will be NO resource sharing. I invite you to download our latest Annual Report from the website (on the main page, scroll down to "Administrivia" and follow the link) to see just how critical our situation has become. Thanks for your interest in SETI science, pattern recognition, and LDEs (interests which many of our members share). 73, Paul N6TX -------------------------------- H.

The upper frequency limit is atmospheric, rather than ionospheric and is somewhat shorter than 1.5cm. The lower frequency limit for SETI tends to be set by galactic noise. DBS satellites operate at around 3cm, so the atmosphere and ionosphere have to be transparent up to at least that sort of frequency.

Astronomers = have pinpointed a planetary system which resembles our own solar system, = raising hopes of the discovery of Earth-like planets capable of bearing l= ife.

For the first time, they have identified a Jupiter-like plan= et, orbiting a star like the sun, at much the same distance from the pare= nt star as Jupiter is from the sun. 

The star, known only as= HD70642, is 90 light years away in the constellation Puppis. Scientists = estimate this star is orbited, once every six years, by a planet about tw= ice the mass of Jupiter.

"This is = the closest we have yet got to a real solar-system-like planet, and advan= ces our search for systems that are even more like our own," said Hugh Jo= nes of Liverpool John Moores University, who announced the discovery yest= erday at a conference on extrasolar planets in Paris. 

He an= d colleagues used a 3.9 metre Anglo-Australian telescope at Siding Spring= s in New South Wales for the work. 

Until 1995, there was no= evidence at all of planets orbiting other stars. Since the first dramati= c discovery eight years ago, researchers have identified more than 100 pl= anetary systems within 150 light years of Earth. 

No one has= seen any of these planets: researchers infer the presence of an orbiting= planet from a kind of wobble in the light from the parent star. The tech= nique is reliable but has limitations.

N= ASA'S ASTRO-VENTURE HELPS STUDENTS EXPLORE HABITABLE PLANETS

As NA= SA embarks on new missions to Mars in the search for evidence of life, st= udents now have access to virtual tools that will help them understand th= e conditions that make human life possible on Earth and how to design a h= abitable fictional planet.

On July 1, 2003, three new modules were= added to NASA's award-winning Astro-Venture Web site developed at NASA A= mes Research Center, Moffett Field, Calif., as part of NASA's educational= goal to inspire students to pursue careers in math, science and technolo= gy. The site is an educational, interactive, multimedia Web environment i= n which fifth- through eighth-grade students emulate NASA occupations and= use scientific inquiry, to search for and design planets with the necess= ary characteristics for human habitation. The original astronomy unit and= the three new modules - geology, biology and Earth science, complete the= Earth system science unit for middle school students.

"Astro-Vent= ure is an excellent tool to assist educators in delivering exciting NASA = research to our future generation of explorers," said Donald James, NASA = Ames education director. "The site exposes students to the compelling top= ic of astrobiology and the wide variety of careers that support this area= of research." Astrobiology is the study of the origin, evolution, distri= bution and destiny of life in the universe.

In the atmospheric science module, students can manipulate the amo= unt of different gasses in our atmosphere and draw conclusions as to whic= h proportions are necessary for human survival.
