Home Desporto Nasas Dawn finds key ingredients for alien life on dwarf planet Ceres

The spacecraft contains a Viable or InfraRed Mapping Spectrometer (VIMS) that is able to detect organic materials on the planets surface. The discovery was made by the Dawn mission, which has previously found evidence of water ice at the planets poles and carbonate minerals, that appear to be responsible for the mysterious bright spots on the surface.NASAs Dawn spacecraft recently detected organic-rich areas on Ceres. Dr Simone Marchi, from the Southwest Research Institute, and an author of the study, said: This discovery of a locally high concentration of organics is intriguing, with broad implications for the astrobiology community. With this new finding Dawn has shown that Ceres contains key ingredients for life. The material was found near a almost 50-km-wide crater in the planets northern hemisphere. Kim Kardashian Goes Platinum Blonde Again & Flaunts Major Cleavage So shaken is the mother of two, she said she struggles to even speak about what happened. The second time she went blonde it was a wig . The exact compounds cant be identified but they do match tar-like minerals such as kerite or asphaltite. Organic compounds are volatile and would be easily destroyed by the intense heat of an asteroid impact. The compounds wouldnt have survived such a powerful, high-heat impact, the study says, but its not fully understood how exactly they moved from inside the planet to the surface. Ceres was formed about 4.5 billion years ago.Put Ceres down on the list of places in the solar system that could have once harbored life or may be hiding it now, alongside Mars, Titan, Enceladus, Europa and some other far-out locales. The dwarf planet is also believed to have an under-surface ocean.The discovery indicates that the starting material in the solar system contained the essential elements, or the building blocks, for life, Russell said. New origami-inspired shield deflects handgun bullets When expanded which takes only five seconds it can provide cover for officers and stop bullets from several types of handguns. Kevlar fabric is very flexible, but it is susceptible to fraying and abrasion, whilst also being sensitive to sunlight and water. At around 600 miles across, Ceres is the largest object in the asteroid belt found between the orbits of Mars and Jupiter. Such a find would also snatch away the title of Coolest Dwarf Planet from Pluto, dealing that plucky iceball yet another degrading blow. Instead, scientists think the asteroids core continues to be hot, retaining some of the heat from its formative days, and this heat interacts with other materials within the asteroid to create the organic compounds.We can not exclude that there are other locations rich in organics not sampled by the survey, or below the detection limit, study lead author Maria Cristina De Sanctis, of the Institute for Space Astrophysics and Space Planetology in Rome, told Space.com via email. The addition of organic material makes the dwarf planet a promising environment for prebiotic chemistry.Composite image of the area around Ernutet Crater. Dawn spacecraft data show a region around the Ernutet crater where organic concentrations have been discovered (labeled a through f). Teenage boy badly hurt after shark attack off Australian coast He was quickly hauled onto a boat where a tourniquet was applied to his leg to stem heavy bleeding which left him unconscious. Ballantyne called Dickson an awesome person and also someone who cares about his friends and family. This is the first clear detection of organic molecules from orbit on a main belt body, said researcher Maria Cristina De Sanctis from the National Institute of Astrophysics in Rome. Indeed, Ceres shows clear signatures of pervasive hydrothermal activity and aqueous adjustment, they wrote in the new study. The finding helped researchers explain that water ice existed beneath the surface of the dwarf planet, especially in the regions near the planets poles.
