  1. Science Movie Club: ‘Contact’

    Yes, there actually are astronomers looking for intelligent life in space. The 1997 film adaptation of Carl Sagan’s ‘Contact’ got a lot of things right … and a few things wrong. Radio astronomer Summer Ash, an education specialist with the National Radio Astronomy Observatory, breaks down the science in the film.

  2. BBC World Service - Discovery, The Alien Equation

    50th anniversary of the equation that launched the search for ET.

    Kevin Fong celebrates the anniversary of one of the most iconic equations ever written. The Drake Equation was created by Frank Drake some half a century ago in a bid to answer one of the most profound questions facing science and humanity: are we alone? Its creation launched a 50 year, genuine scientific endeavour to search for ET, known as SETI: The Search for Extra Terrestrial Intelligence. Kevin visits the SETI Institute in Northern California, to meet the great man himself, Frank Drake, and some of his scientific colleagues who have spent most of their working lives hunting for signs of alien life, out there in the cosmic ether.

  3. Sara Seager: Other Earths. Other Life. - The Long Now

    We are one tool away from learning which distant planets already have life on them and which might be welcoming to life.

    MIT Planetary Scientist Sara Seager is working on the tool. She is chair of the NASA team developing a “Starshade” that would allow a relatively rudimentary space telescope to observe Earth-size planets directly, which would yield atmospheric analysis, which would determine a planet’s life-worthiness.

    Despite 1,000-plus exoplanet discoveries by the Kepler spacecraft and the hundreds more expected from the Transiting Exoplanet Survey Satellite after 2017, neither instrument can make detailed observation of the atmosphere of small rocky planets, because each star’s brilliance overwhelms direct study of the rocky motes that might harbor life. A Starshade cures that.

    A former MacArthur Fellow, Seager is author of Exoplanet Atmospheres (02010) and an astrophysics professor at MIT. Her maxim: “For exoplanets, anything is possible under the laws of physics and chemistry.”

  4. Guardian Science Weekly - The search for extraterrestrial intelligence

    This week it was revealed that astronomers are about to start the most intensive ever search for alien life. The Breakthrough Listen project will scan stars in 100 galaxies for radio and optical signatures that indicate someone, or something, is out there.

    Until now, the search for extraterrestrial intelligence - or SETI - has been met with an eerie silence. What makes scientists so convinced it’s worthwhile looking for alien life?

    What are the chances that we’ll find it? And should we consider beaming our own messages out into the cosmos?

    Joining Hannah Devlin are astronomer Frank Drake; Professor Geoff Marcy and Dr Andrew Siemion, both from the University of California, Berkeley; and Dr Nick Lane, an evolutionary biochemist at University College London, whose work looks at how life started on Earth.

  5. Interview with Dr. Jill Tarter

    Dr. Jill Tarter holds the Bernard M. Oliver Chair for SETI Research at the SETI Institute in California. She has spent majority of her professional career attempting to determine whether we are alone in the universe, and among her other prior positions, she was the Project Scientist for NASA’s SETI program. In this interview, Dr. Tarter tells us about the latest in SETI research, including what we can expect the Square Kilometer Array to contribute to SETI.
