... Sourcebook Project Sourcebook Subjects Natural lasers in the terrestrial and martian skies?In a current laser patent dispute, one side claims that a certain laser patent is invalid because natural phenomena cannot be patented under U.S . law. It seems that last year, Michael Mumma and colleagues at Goddard Space Flight Center and the University of Maryland discovered a 10-micrometer (infrared) laser in the Martian atmosphere. This laser is located about 75 kilometers above the surface, is optically pumped by the sun, and radiates an astonishing 101 2 watts. The terrestrial atmosphere may contain a natural 4.3 -micrometer laser, for auroras are accompanied by very intense molecular emissions at this wavelength.

The outer atmospheres of these planets act like radio lasers, which store radio energy and then release it suddenly when stimulated by weaker solar signals. The earth's laser operates between frequencies of 50 and 600 kilohertz. Its emissions are known as the "auroral kilometric radiation" or AKR. While some of these terrestrial emissions are spontaneous, others are stimulated by Type-III solar radio bursts. The newly discovered Jovian laser operates at hectometric wavelengths and is also triggered by the solar radio bursts. ...

The satellite, called Lageos, is covered with laser reflectors so that it can be tracked with high precision. At its altitude of 3700 miles, the earth's atmosphere is supposed to be so thin that friction will bring the satellite only 1/250th of an inch closer to the earth each day. The trouble is that Lageos actually falls at ten times this rate. In 1979 it descended 60% faster than it does now. Lageos will stay in orbit several hundred thou-sand years, but space scientists are understandably concerned about their theories about the ...

Science Frontiers ONLINE No. 98: Mar-Apr 1995 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects An Unknown Atmospheric Light Phenomenon Between 1981 and 1985, hundreds of strange lights have appeared in a small valley in central Norway. Named after the valley, the lights have been named: The Hessdalen Phenomenon. A research station was set up in the valley in 1983. During January-February 1984, eight different kinds of instruments were in use, with the following results: Camera with grating : Three pictures showed a continuous spectrum. No spectral lines were seen on any picture. IR-viewer: This instrument was used too little to drawn any conclu sion. Spectrum-analyzer: Sometimes there were electromagnetic signals with harmonics of about 80 ... showed up. There also seemed to be a correlation with the mag netic pulsation. Radar : The lights could be seen on radar. The speed varied all the way from 0 to 30,000 km/hour. Sometimes the radar saw something moving at a low speed, but no lights were seen by eye. Clearly, there was something there, but only the radar showed it. Laser : A laser-beam was directed toward the light, and the behavior of the light changed. Geiger-counter : No radioactive radi ation was detected. But the source was 1 km away when this instrument was used.

... 'miracle' of life satisfactorily." (Davies, Paul; "The Creative Cosmos," New Scientist, p. 41, December 17, 1987.) The superorganism. One week later, O. Sattaur expanded on the Gaia concept. He quotes J. Lovelock's definition: ". .. the physical and chemical condition of the surface of the Earth, of the atmosphere and of the oceans has been, and is, actively made fit and comfortable by the presence of life itself...in contrast to the conventional wisdom which held that life adapted to planetary conditions as it, and they, evolved their separate ways." Mainstream science has shown scant love for the Gaia concept, probably because of its holistic nature. The idea of the earth being ... found in nature." The author of this introductory paragraph, P. Davies, asks, as we all do, "What is the origin of this creative power?" In groping for an answer, he presents first a common example of "blind" organization: the hexagonal convection cells in a pan of heated water. Using for a stepping stone the cooperative action of atoms in a laser, he leaps to the development of an embryo from a single strand of DNA! All such systems are "open"; that is, energy can flow in and out. They are also nonlinear, which means that chaotic, unpredictable action may occur. Davies implies that such action can be "creative," almost as if they possessed free will! His final example is that of ...
