Is there life outside of Earth? Is there a future for humankind in outer space? These are but a few among the many questions that this field of science attempts to answer. Exobiology (also Astrobiology) is an interdisciplinary field that combines astronomy, biology and geology to study the origins, evolution, distribution and future of life in the universe. Thus, it is concerned with how life began, the search for extraterrestrial life, the effects of outer space on living organisms, the future of the Earth, and the possible habitability elsewhere in the universe .
NASA's Chandra Finds Black Holes Are 'Green'By making the first direct estimate of how efficient or "green" black holes are, this work gives insight into how black holes generate energy and affect their environment.
Cornell Study Finds That Galaxies Cluster Near Dark MatterTry mixing caramel into vanilla ice cream -- you will always end up with globs and swirls of caramel. Scientists are finding that galaxies may distribute themselves in similar ways throughout the universe and in places where there is lots of so-called dar
Deadly Astronomical Event Not Likely To Happen In Our Galaxy, Study FindsSome scientists have wondered whether a deadly astronomical event called a gamma ray burst could happen in a galaxy like ours, but a group of astronomers have determined that such an event would be nearly impossible.
Hubble Finds 'Tenth Planet' Is Slightly Larger Than PlutoNASA's Hubble Space Telescope has resolved the "tenth planet," nicknamed "Xena" for the first time, and has found that it is only just a little larger than Pluto.
Stellar birth control in the early universeAstronomers found that "old stars" dominated many large galaxies in the early universe, raising the new question of why these galaxies progressed into "adulthood" so early in the life of the universe.
Methane-belching Bugs Inspire A New Theory Of The Origin Of Life On EarthTwo laboratories at Penn State set out to show how an obscure undersea microbe metabolizes carbon monoxide into methane and vinegar. What they found was not merely a previously unknown biochemical process--their discovery also became the inspiration for a
Liquid water on Saturn moon could support lifeScientists have found evidence that cold, Yellowstone-like geysers of water are issuing from a moon of Saturn called Enceladus These geysers are apparently fueled by liquid reservoirs that may contain organic materials that could support life.
Watching how planets formWith the VISIR instrument on ESO's Very Large Telescope, astronomers have mapped the disc around a star more massive than the Sun.
Ancient rocks 'built by microbes'The article describes the odd-shaped rocks in the Pilbara region of Western Australia. Accordingly, there was compelling evidence that they were built by microbes 3.43 billion years ago.
Sterile surface of moon may contain clues to life on EarthIt is the moon's lack of life, atmosphere and geological activity, such as volcanoes or shifting continental plates, that makes it such a good place to look for signs of life. Since the Apollo missions did not scrape the moon surface, a return mission is
Scientists find the reason behind black holes' light showsA team of astronomers led by the University of Michigan may know how black holes are lighting up the Universe. New data from NASA's Chandra X-ray Observatory show, for the first time, that powerful magnetic fields are the key to these brilliant and startl
