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?

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. 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? — by one side of the aisle, solely for the purpose of generating passion that could be shaped into various agendas,” Mr. MacFarlane said in November.
Hubble data predicts Milky Way galactic collision When Galaxies Collide! It sounds like an early science fiction novel. However, analysis of Hubble measurements shows that our own Milky Way galaxy is moving toward a head-on collision with our nearest neighbor, the Andromeda galaxy (also known as M31). The collision will start in about four billion years, and over the following three billion years the two spiral galaxies will coalesce into a large elliptical galaxy. 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. We undertake fundamental research in many areas, including: The study and modeling of exoplanets, their characteristics and climates. The study of planet formation and solar system meteoritics and early chemistry.The study of Earth and Martian paleoclimate.
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.

Extraterrestrial Life The official U.S. government position on extraterrestrial life and the three major efforts to search for it. Clockwise from top left: The development and testing of hypotheses on extraterrestrial life is known as "exobiology" or "astrobiology", although astrobiology also considers Earth-based life in its astronomical context. Many scientists consider extraterrestrial life plausible, but there is no direct evidence of its existence. Since the mid-20th century, there has been an ongoing search for signs of extraterrestrial life, from radios used to detect possible extraterrestrial signals, to telescopes used to search for potentially habitable extrasolar planets. It has also played a major role in works of science fiction. Science fiction works, especially Hollywood's involvement, has increased over the years the public's interest in the possibility of extraterrestrial life.
NASA Endeavor STEM Teaching Certificate Project. Live, online STEM education courses as part of a STEM Master's Degree or STEM Certificate. Overview: Is there life out there? Searching for life in the universe requires a deep understanding of the characteristics and attributes of Earth that make our planet habitable (e.g., our Sun, tectonic plate movements). Learn how scientists use physics concepts such as Kepler's Laws, the Doppler Effect, phase changes, and properties of matter to search for planets in faraway galaxies that just might support life forms. Bring exciting astrobiology content into your classroom to excite students about learning in meaningful contexts and address Next Generation Science Standards. What can I expect from this course?
