Cosmic Journeys Cutting-edge stories about the origins of the universe, black holes, exploding stars, the search for ET life, and the nature of the planets. How did the universe begin? Where will it end? Are there other worlds like Earth? A groundbreaking series combs the rubble of exploding stars and the collision of worlds in search of answers to our most searching questions about the cosmos. The Stanford Astrobiology Course Welcome and introduction to website Astrobiology is at once one of the newest of scientific meta-disciplines, while at the same time encompassing some of our oldest and most profound questions. Beyond strictly utilitarian concerns, such as “what is for dinner?” and leaving offspring, asking the three great questions of astrobiology seems to be embedded in what it means to be human. While these questions are ancient questions, we now have the technological tools to grapple with them at a whole new scientific level. During recent centuries the Copernican and Darwinian Revolutions laid the way for Astrobiology.
Astrobiology Center The Columbia Astrobiology Center (NYC-Astrobiology Consortium) The Columbia Astrobiology* Center represents a unique consortium of Columbia University departments, the Goddard Institute for Space Studies (NASA), and the American Museum of Natural History. It is an interdisciplinary effort dedicated to investigating the wide range of phenomena that may participate in the origin and evolution of life on Earth and beyond. Astronomy Picture of the Day's Educational Links What follows is a list of resources that excel in astronomy education. Each resource is distinctly different - they have been chosen to highlight a wide range of interests. We believe the list is topologically complete in that there are no publicly advertised astronomy resources on the WWW that cannot be found by following the internal links of these resources.
Why the USA and NASA need astrobiology I am an astrobiologist, for 50 years an astronomer, and before that a physicist. With my colleague and friend Roger Angel, we started the process of learning how to detect Earth-like planets in 1985. I am a co-author of the NASA booklet The Terrestrial Planet Finder. I have served with scientific and technical teams to develop that mission since 1995. I have been a professor of astronomy at U. Arizona for the last 30 years, and I became P.I. for the Arizona team (LAPLACE, Life And PLanets Astrobiology CEnter) in 2003. Seth MacFarlane Champions New ‘Cosmos’ Series on Fox Photo WASHINGTON — When some of the nation’s brightest minds gathered here at the Library of Congress to celebrate Carl Sagan, the pioneering astrobiologist, the first guest speaker was someone with no professional background in science. It was Seth MacFarlane, the multitasking comedian and creator of “Family Guy,” who gave an impassioned speech to the crowd of Ph.D.s and NASA advisers on how scientific achievement had “ceased in many parts of this country to be a source of pride.” “Long accepted scientific truths have been brought into question largely — who are we kidding?
The Cosmic Distance Scale The Cosmic Distance Scale By Maggie Masetti This feature will give an impression of how immense our Universe is by employing a method used many times in "Power of 10" films - that is, starting with an image of the Earth and then zooming out towards the furthest visible reaches of our Universe. This is not, however, an exercise in "powers of 10" - on the contrary, our goal is to show you astronomical distances without scientific notation. We instead focus on the large number of zeros that are in astronomical distances when we measure them with a familiar unit like the kilometer. The number of zeros increase with each zoom, though not at a constant rate. Why was this feature written? Astrobiology: Life in the Universe How Did Life Become Complex? A species of yeast (Saccharomyces cerevisiae) seen in a scanning electrograph image. Credit: NASASource: [astrobio.net The evolution of multicellular life on Earth happened with a number of key transitions from simple organisms to complex. Could the same transitions happen on other worlds? Frank Rosenzweig, an evolutionary geneticist at the University of Montana, is looking into such questions over the next five years with funding from the NASA Astrobiology Institute. His lab studies how life evolves “complex traits,” factors that influence everything from lifespan to biodiversity.
Finding Life Beyond Earth PBS Airdate: October 19, 2011 NARRATOR: Is Earth the only planet of its kind in the universe, or is there somewhere else like this out there? Is there life beyond Earth? The search for alien life is one of humankind's greatest technological challenges. And scientists are seeking new ways to find answers. JIM GREEN (Director, Planetary Science Division, NASA): We're pushing the boundary of information of where life can exist, past the earth and out into the solar system.
