Astrobiology Vol. No. 6823 (22 February 2001). PDF K) Cover illustration (Image courtesy of Jacey) Commentators often bemoan what they see as the increasing tendency of research to be inward looking, self-serving and specialized. Happily, some things buck the trend. Astrobiology does this in dramatic fashion, and is the theme for the eclectic selection of review, progress and commentary that follows. Astrobiology is nothing less than the study of life in the Universe. It encompasses fields as diverse as geology, astronomy, evolutionary and developmental biology, human physiology and palaeontology. National Astrobiology Institute It would be easy to dismiss astrobiology as either a pointless fad or a new brand for goods long past their sell-by date (does anyone remember 'exobiology'?). But such condemnation misses the point. In an age of increased narrowness of research goals, it is invigorating to lift one's eyes to the stars and consider life in its broadest sense. One consequence of astrobiology will be to deepen our understanding of our own place in the Universe, our uniqueness and our potential. As this collection of articles shows, many ventures labelled as astrobiology are quixotic, even romantic, perhaps some way from the usual stuff of science. Disagreement abounds, and answers to many astrobiological problems may never be found. But that there is no universal truth is true for all science: the stimulation is in the quest, not in the finding. How much more valid is that statement when the quest encompasses the spatial and temporal breadth of the cosmos?

26. Astrobiology The key to finding life on other planets just might be here on Earth. http://www.acfnewsource.org/science/astrobiology.html

SEARCH STORIES: Navigation Astrobiology KPIX-TV (San Francisco): 9/4/02 The key to finding life on other planets just might be here on Earth. Are we alone in the universe? Philosophers and astronomers have looked to the stars to answer this question for hundreds of years. But now, some scientists are hoping to learn more about alien life forms by looking not into outer space, but at some of the most extreme environments here on earth. "Astrobiology has to do with how life interacts with planets, moons, and other bodies in our cosmos," says Dr. Barry Blumberg, director of NASA's Astrobiology Institute. Blumberg says there may be life on these planets that is similar to what we find on earth. "The notion is that if we understand it on earth, it will help us to identify life on other planets." One of the first steps in understanding life on earth is exploring some of the extreme environments in which life can survive. Dr. Jonathan Trent, an astrobiologist at NASA Ames Research Institute, says that until recently, scientists believed that the highest temperature to which life could adapt was about 140 degrees Fahrenheit. But over the past 20 years, that assumption has been proven wrong. Researchers have since discovered organisms that can live in deep-sea vents where the temperature rises to about 235 degrees F. (The pressure prevents the water from boiling.) "That seems to be holding as the record so far, but we continue to search new environments," Trent says. Some of the new environments Trent is exploring include underground springs and pools. A few years ago, Trent and his colleagues brought specially outfitted cameras to Yellowstone National Park and submerged them in the park's hot springs, geysers, and sulfur pools. They knew that single celled organisms like bacteria could survive in temperatures above boiling, but were hoping to find larger creatures living in high temperatures in the park. Although they didn’t find anything living at record-breaking temperatures, the cameras proved themselves valuable research tools by capturing images of insect larvae and tiny crustaceans living in temperatures of about 113 degrees F.

Lynn J. Rothschild Mail Stop 239-20 NASA Ames Research Center Moffett Field, CA 94035-1000 Lrothschild@mail.arc.nasa.gov Astrobiology is the scientific study of the living universe, how it arrived at this point in time, and where it is heading. It starts with life on Earth, the only place where life is known to exist, and extends into the farthest reaches of the cosmos. It ranges in time from the big bang and continues on into the future. Astrobiology covers a diverse range of topics which can be categorized under major questions: Where did life come from? What is its future? Are we alone in the universe? Like any newborn, Astrobiology is growing and changing rapidly. Thus, this article can only give an overview of Astrobiology rather than covering all the latest research findings.

Because ultraviolet (UV) exposure increases with altitude, the microorganisms found in these lakes can provide clues to how life survived on a long-ago Earth without oxygen in its environment. That, in turn, can help us understand how life could arise and adapt on other planets. "What's Living in the World’s Highest Lake?"

33. Astrobiology Research Consortium At UW-Madison The primary efforts of the Wisconsin astrobiology Research Consortium (WARC) lie in development of stable isotope biosignatures for elements that are http://www.geology.wisc.edu/astrobiology/

Our Team is focused on developing the biosignatures required for detecting the signatures and paleoenvironments of life in the earliest part of Earth's history or on other planetary bodies. Finding living or unambiguous fossilized cells on another planetary body would be irrefutable evidence for life beyond Earth, but the footprint for this type of life detection is small. In addition, there are severe preservational limitations for fossils, particularly for ancient microfossils, and this poses challenges for detecting ancient life even on Earth. The exploration footprint for organic molecules and chemical and mineralogical biosignatures is large, however, because these comprise large inventories of the surface deposits on planetary bodies. The primary efforts of the Wisconsin Astrobiology Research Consortium (WARC) lie in development of stable isotope biosignatures for elements that are critical to life (C, N, O), as well as those that were involved in biogeochemical cycling or microbial redox metabolism (S, Ca, Mg, and Fe) and whose compositions may be preserved in the rock record. Our ultimate goal is to develop an interpretive framework so that mineralogical and isotopic measurements using Earth- or space-based instrumentation can provide definitive answers concerning life detection. We are funded by the NASA Astrobiology Institute (NAI) , a multidisciplinary umbrella for conducting research on the origin and evolution of life on Earth and elsewhere in the Solar System. Our team is one of 16 teams who are members of NAI. NAI-sponsored research and outreach efforts involve hundreds of scientists and educators with backgrounds and interests that range from geology to biology to astronomy.

Our unbiased sample is comprised of 309 stars with masses 0.7-2.2 Msun and ages from 3 Gyr that lack excess emission at wavelengths <=8 microns.

University of Kansas Astrobiology Astrobiology is concerned with the possiblity of the development and detection of life elsewhere in the Universe, as well as the effect of astrophysical processes on life on the Earth. A wide variety of research areas meet here, including astrophysics, astronomy, biochemistry, evolutionary biology, paleontology, atmospheric science , and a host of others. Do Gamma-Ray Bursts Damage Planetary Biospheres? GRBs are the most powerful known explosions in the Universe, sending out beams of radiation that have been an active research interest for more than 30 years. Only in the 90's was it firmly understood that they are at huge, cosmological distances, and therefore correspondingly powerful. They are probably created by the energy released when a star collapses to form a black hole. For more background you can read this public discussion produced by NASA, or a slightly more technical discussion with an entry into the scientific literature here. Knowing the power of these bursts and their average rate throughout the Universe, it is possible to calculate the likely rate of events in our "neighborhood". In this case, any burst on our side of the Milky Way galaxy is likely to be dangerous, if it is pointed at the Earth. Several groups have independently estimated that one or more GRBs is likely to have "blasted" the Earth from a distance of 6,000 light years, or even less, within the last 500 million years or so. Some evidence to support this rate has come from the observation of a GRB
