 | CONFIRMED - Water and Life on MARS!! Space probe of NASA confirms water existence in Mars With the advance of the technology and developed research being, expectation is of that, in next the 30 years, the least a bacterium extraterrestrial either discovered. "I am optimistical with regard to the possibility to find a form life simple. I wait that it is found still during my time as professional astronomer", says Carlos Alexander Wuensche, astrophysical of National institute of Space Research (Inpe). This because the bacteria survive in adverse conditions. Many species support high acidity, much radiation, lack of oxygen e low temperature. "To have an idea, 95 of the terrestrial biomass are bacterium", it remembers. Generally, the majority of them lives until a meter below of the surface, what it would make it difficult the finding. Two meteorites are in study to see if they possess life forms come from another place of the Universe. They are the meteorite of Murchinson e of Allende, found, respectively, in Australia and Mexico in 1969. It has few years, scientists had evidenced that some structures gifts in the intitled meteorite Lh84001, finding in the decade of 1980, they were terrestrial. At the same time, in Mars, the "jeeps" of NASA and the Mars sounding lead Reconnaissance Orbiter had detected chemical composites that they indicated liquid water presence in the first millions of years of the existence of Mars, leading to a possible condition of primitive habitability. In the passed year, a similar planet to the Earth was discovered, that it gravitates around the star Gliese 581. Before, already they had found other similar around Gliese 876. Both had generated expectation. first, mainly, for being located in a region where water in liquid state can exist, therefore the average temperature superficial it must be between 0 C and 100 C. It possesss five times mass of the Earth, what its bigger gravity leaves more and the atmosphere dense, but it does not modify the expectation of that it can have forms life primitive. Life of carbon and importance of the water "To exist life in other planets a series is necessary of factors", affirm Wuensche. Generally, the life that if it looks in the space it is based on carbon. This element allows that they happen chemical processes that give origin to the life. Together with the carbon, is necessary to exist the water in liquid state. The luck is that the elements basic - water, carbon, hydrogen, nitrogen and oxygen - it stops the creation is spread in abundance for the Universe. To have itself an idea of the importance of carbon, the DNA is made of carbon, hydrogen, nitrogen and plus some joined elements. The carbon is formed in, practically, all the reaction processes nuclear in the interior of the stars, therefore easily it is found. "With them, it is possible to form complicated molecules as amino acids, as the glicina, one of 20 basic amino acids for the life", it explains. "We find some, for example of the families of the alcohol and of acetone, spread for the interstellar way - them stars - in form of gas and ice", Wuensche counts. These composites do not need one rocky planet to be formed and is important for development of a complex chemistry. Recently, they had been discovered chemical composites sufficiently sophisticated, based in carbon rings, in other points of the Way same Láctea and in others next galaxies. However, only the carbon is not enough. "For the life based on the chemistry of carbon has that to have water", it says the astrophysical one. Therefore it is so looked to Universe the rejection. "It is solvent an important one that she allows that the molecules biggest if move and "they beat" ones in the others. Forming other molecules", affirm. The water is solvent a universal one, found in abundance in the form of ice and gas. Together, the water and the carbon they form the brick and the cement for the construction of the life. Because life in the Earth exists The Earth has, approximately, 4,5 billion years. Quickly, it has about 3,8 billion years, if they had formed the microorganisms as bacteria. "By 75% of the time the life in the Earth was dominated by beings unicellular", the researcher counts. "The Cambriana Explosion, period that they had appeared different animals, occurred in 1/8 of this time. Being that, the mammals had appeared have 100 million years", count. The human being it obtained to order radio controls for it are of the planet has 100 years behind. E, from the decade of 1930, to catch radio controls. "To form complex life is not simple", says. |
 | Well, That Was Odd: A Little Priest Sorcyress and I singing a Little Priest for the benefit of all the people who couldn't be at the theater yesterday. We suck, rather. My excuse is that I know about as much about singing as I do about complex chemistry. Also the house was on fire so we were distracted by that. Yeah. Anyways. Enjoy. We own neither Sweeney Todd nor a Little Priest but Sor and I rather firmly belong to ourselves. |

 | 8405 Asbolus, Centaur's Crater This is an artist's impression of object called 8405 Asbolus, a 48-mile-wide (80-kilometer) chunk of ice and dust that lies between Saturn and Uranus. Astronomers using NASA's Hubble Space Telescope were surprised to find that one side of the object (also called a Centaur) looks like it has a fresh crater less than 10 million years old, exposing bright underlying ice Hubble didn't directly see the crater - the object is too small and far away - but a measure of its surface composition shows a complex chemistry. The event that caused the impact crater on 8405 Asbolus may also have knocked it out of the Kuiper belt, a ring of comet nuclei just beyond Pluto's orbit. |
 | Huygens Landing Site Revisited. First Color View of Titan's Surface One year ago this week, on January 14, 2005, the European Space Agency's (ESA) Huygens probe reached the upper layer of Titan's atmosphere and landed on the surface after a parachute descent 2 hours and 28 minutes later. As part of the joint NASA/ESA/ASI mission to Saturn and its moons, the Huygens probe was sent from the Cassini spacecraft to explore Titan, Saturn's largest moon. Titan's organic chemistry may be like that of the primitive Earth around 4000 million years ago, and it may hold clues about how life began on our planet. The Huygens mission has been an outstanding engineering and scientific success, one of the most complex and scientifically rewarding space missions to date. Huygens Landing Site Revisited Click image for high resolution version. Click here for a link to the movie. The touchdown on the surface of Titan marked the farthest a man-made spacecraft has successfully landed away from Earth. Clear images of the surface of Titan were obtained below an altitude of 40 kilometers (25 miles) -- revealing an extraordinary world that resembled Earth in many respects, especially in meteorology, geomorphology and fluvial activity, but with different ingredients. The images show strong evidence for erosion due to liquid flows, possibly methane. Huygens enabled studies of the atmosphere and surface, including the first in-situ sampling of the organic chemistry and the aerosols below 150 kilometers (93 miles). These confirmed the presence of a complex organic chemistry, which reinforces the idea that Titan is a promising place to observe the molecules that may have been the precursors of the building blocks of life on Earth. Huygens Titan Mosaic #1 Around 260 scientists and up to 10,000 engineers and other professionals from 19 countries overcame cross-cultural and multi-disciplinary differences to achieve an astonishing co-operation. ESA's Huygens project scientist, Jean-Pierre Lebreton said, "This mission took two decades to accomplish and pushed the limits of our capabilities, whether scientific, technological or organisational. But the scientists and engineers used their skills and intelligence to overcome technical, political and celestial barriers to their goals. "In the end, they triumphed spectacularly and, apart from the amazing scientific return, the mission should be an inspiration and a lesson for organisations of all kinds, in all sectors, of how people can work together." |
