Human beings perceive objects by seeing in the "normal" optical range. This is purely an evolutionary imperative. Evolution could just as easily given us eyes that work in the infrared to know what is going on around us. If this was the case we would experience no night at all. The night sky would be just as clear as the sky in the day. At night the sky would be lit by hydroxyl molecules emitting infrared light in the form of a mass of narrow emission lines. It would be like daylight, though a few stars could be seen along with the Sun and the Moon. Telescopes operating in the infrared get over this problem by using limited apertures and special filters. These filters use a photonic lantern system to move the light into parallel tracks. A Bragg filter reflects out the tracks and lets wavelengths between lines through. Many IR telescopes are in space where such a filter is unnecessary. The space telescopes beam data back to Earth. http://www.adventure--australia.bl

Information about the climate five centuries ago has come to light from leaves found in an old Bible. Susana Melo de Howard was returning the 1540 Great Bible back into its humidity-controlled room when she saw the preserved leaves. The book is kept at the University of Western Australia. It came from the monastery of Ely Cathedral in England and was the first English translation of the Bible. William Tyndale was executed in Belgium for this "crime". The West Australian university got the book at the bargain price of $500 in 1977. No one had viewed the Bible in the last twenty years. Detective work began on the leaves as soon as they were found. By sending photographs of the leaves to academic centers all around the world, they were identified as Wych elm which was common in England 500 years ago. Carbon dating showed the leaves were placed in the Bible in the 1560s. Nitrogen was high on wetland farms in those days. Mercury, chromium and arsenic pollution was also

Plants don't eat animals though some eat flies? Definitely not true. A plant has been discovered in Cape York northern Australia that eats rats. A large pitcher plant, a plant that eat flies, has been discovered. It is a vine and has been called "Tenax". It was found in a swamp. Most new species are found in Sumatra, Borneo or New Guinea. It was a surprise to find a new species in Australia. Pitcher plants are found just about everywhere in Australia. They grow as weeds, even getting into lawns. But even the thought of one being large enough to devour a rat boggles the mind. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://www.feeds.feedburner.com/AdventureAustralia http://www.technorati.com/blogs/ http://adventure--australia.blogspot.com . . . . . . . . . . . . . . . . . .

It isn't ours says the US, Russia and Germany. A mysterious metal ball, two hemispheres welded together, has fallen to earth in Namibia. The "ball" is 35 centimeters wide and cut a groove in the ground on impact 33 centimeters deep and 3.8 meters wide. The hollow sphere is not dangerous - it isn't an explosive devise. There were two recent orbital crises with satellites crashing to the ground: NASA's Upper Atmosphere Research Satellite and Germany's Roentgen Satellite. The mystery object is not part of any of these. The Phobos-Grunt Mars Probe made in Russia will also soon come down. There is the possibility that it could be from a satellite much older, something that has been orbiting for a long time. If this is the case, ownership of the space debris may never be known because no country wants it known that satellite parts can fall at random from the sky. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http:
