ASTROBIOLOGY COURSE OVERVIEW Astrobiology provides a fertile domain for students to struggle with fundamental questions of scientific knowledge. Students will learn that scientific knowledge is not a set of accumulated facts, but is a dynamic and, at times, confusing and amorphous set of current speculations. Students will observe and experience how this knowledge base evolves through the addition of new data and the emergence of new means of understanding the data. They will learn about, explore and participate in the real processes of science research and discovery, including modeling, setting up experiments, testing hypotheses, making systematic field observations, and doing image and data analysis. Research activities such as WebQuests and long-term, independent experiments will enable students to DO rather than TAKE astrobiology.

The Encyclopedia of Astrobiology, Astronomy, and Spaceflight FRONT PAGE NEWS ARCHIVE NEWSLETTER ... Z this site WWW panspermia An idea, with ancient roots, according to which life arrives, ready-made, on the surface of planets from space. Anaxagoras is said to have spoken of the "seeds of life" from which all organisms derive. Panspermia began to assume a more scientific form through the proposals of Berzelius Richter Kelvin (1871), and Helmholtz (1871), finally reaching the level of a detailed, widely-discussed hypothesis through the efforts of the Swedish chemist Svante Arrhenius . Originally in 1903, but then to a wider audience through a popular book in 1908, Arrhenius urged that life in the form of spores could survive in space and be spread from one planetary system to another by means of radiation pressure . He generally avoided the problem of how life came about in the first place by suggesting that it might be eternal, though he did not exclude the possibility of living things generating from simpler substances somewhere in the universe. In Arrhenius's view, spores escape by random movement from the atmosphere of a planet that has already been colonized and are then launched into interstellar space by the pressure of starlight ("radiopanspermia"). Eventually, some of the spores fall upon another planet, such as the Earth, where they inoculate the virgin world with new life or, perhaps, compete with any life-forms that are already present.

Faculty Courses Images GPS Home Welcome to Caltech's Geobiology Home! click on image for caption and additional images Why should geological and planetary scientists be interested in molecular geobiology, and genetics in particular? One answer is simply that genes are fossils. In many cases, genes are extraordinarily ancient in origin and contain information about past events and environments on this planet. There are many examples of this, from the "Snowball Earth" episodes in the Proterozoic triggering evolution of the Superoxide dismutase, to bursts of True Polar Wander during the Cambrian Evolutionary Explosion . A second answer is that understanding how extant organisms function at the molecular genetic level will better enable us to interpret past, present and even extraterrestrial biogeochemical signatures. Though exploring the molecular evolution of organisms and their organic and inorganic products, research in the Geobiology program at Caltech will interrogate the history of life on earth as well as the role the biota continue to play in shaping modern environments.

Research Seminars ... Home Announcements The spring public symposium is scheduled for Feb. 12. Details here Astrobiology at the University of Colorado The field of astrobiology has as its goal understanding the potential and actual distribution of life in our solar system and in the universe. It addresses the origin and evolution of life on Earth, the occurrence of habitats capable of supporting life in our solar system, and the potential for planets and life to exist orbiting other stars. The goal of astrobiology is to utilize modern science to address the age-old question of "are we alone?". Astrobiology is inherently an interdisciplinary field that brings together major aspects of astrophysics, planetary science, geology, atmospheric science, chemistry, molecular biology, and evolutionary biology. In addition, it crosses the boundaries into the humanities, with connections to philosophy, sociology, history, and journalism, for example. The CU Center for Astrobiology is located within the Laboratory for Atmospheric and Space Physics, and acts as a central umbrella to coordinate astrobiology research, teaching, and outreach activities. It is one of fifteen member teams in

Space Science News home Search for life on Mars will start in Siberia NASA funds permafrost study to support astrobiology research May 27, 1999: NASA and Russian scientists have been selected to take the search for life in the solar system to the frozen reaches of Earth. Richard Hoover of NASA's Marshall Space Flight Center and Prof. Elena A. Vorobyova of Moscow State University will investigate the microbiota found in the permafrost and ice of Siberia, Alaska, and Antarctica. NASA's Office of Space Science has announced that their proposal, Permafrost as Microbial Habitat - in-situ Investigation , was one of 18 chosen from 123 proposals submitted for funding under the Joint U.S./Russian Research in Space Science (JURRISS) Program. Right: Hoover displays growing moss that remained alive yet dormant while frozen for 40,000 years in the permafrost of the Kolyma Lowlands of northeastern Siberia. The sample was provided by David A. Gilichinsky and Elena A. Vorobyova of the Institute of Soil Science and Photosynthesis, Russian Academy of Sciences. Links to 1800x1204-pixel, 483K JPG

The existence of life on the planet's oven-hot surface is unimaginable. But microbes could survive and reproduce, experts say, floating in the thick, cloudy atmosphere, protected by a sunscreen of sulphur compounds. Scientists have even submitted a proposal for a NASA space mission to sample the clouds and attempt to return any presumed Venusians to Earth. Read more .
