The Sex Life of 747 Aircraft

In the edition of Science Express on line, from the issue of Science of September 28, 2006, Pierre-Olivier Lagage and colleagues reported the discovery of large quantities of Polycyclic Aromatic Hydrocarbons in the nebula of the incipient Star HD97048. This finding confirms the theory of spontaneous synthesis of biomolecules in grains of dust of the planetary nebulas, not in the deposits of water on the planets. Another finding that supports the theory is that the Polycyclic Aromatic Hydrocarbons were excited by the action of the ultraviolet radiation emitted by the young star.1. In 1999, some astronomers discovered the planet HD 209458b, in orbit around a star in the constellation of Pegasus, at 150 light years from Earth. The planet like-Jupiter is orbiting in three and one half days, facing a sufficiently nearby and brilliant star as to be well observed. Using an ultraviolet spectrograph attached to the Hubble Space Telescope, Alfred Vidal Madjar of the Institute of Astrophysics of Paris and Gilda Ballester of the University of Arizona studied the planet in October and November of 2003, finding atomic Oxygen and Carbon in the outer layers of the planet.2. Jan M. Hollis of NASA’s Goddard Space Flight Center, Frank J. Lovas of the University of Illinois and Philip R. Jewell from the National Radio Astronomy Observatory (NRAO) have written a paper where they reported the finding of glycol-aldehyde in a large nebula near to the center of the Milky Way. Their finding is the first discovery of a simple molecule of carbohydrates out from Earth, at the Interstellar Medium, with which the theory about the synthesis of biomolecules in the Interstellar Medium has been verified.3. Raymond and Beverly Sackler of the Laboratory for the Astrophysics in the Observatory of Leiden have discovered that the Amino acids can synthesize by reactions of gas phase in interstellar clouds by reactions in solid grains of dust, or by aqueous alteration in carbonaceous meteorites. This discovery supports the theory that the intense UV light emitted by the Sun had impeded the formation of amino acids in the interplanetary environment if there were not frozen crystals and solid fractals.4. Perry A. Gerakines, Marla H. Moore and Reggie L. Hudson of the Department of Physics of the University of Alabama have shown experimentally the formation of organic molecules from “icy” mixtures (T20-100 K) due to irradiation (protons of 0.8 MeV) and photolysis (6-10 eV). Biomolecules were synthesized in the central region of the planetary cloud, which contained frozen crystals of water and solid dust.
