A Wonderfully Scientific Science Fiction Film

Last night, thanks to the Wonderfest organization in San Francisco, I got a chance to see a science fiction film that was in theaters for so short a time that if you blinked, you probably missed it. It's called "Europa Report" and it is the story of a crewed expedition to Jupiter's intriguing moon Europa. This world, one of the four large moons of Jupiter discovered by Galileo, is an ice-covered ball that may well have a large liquid ocean under its surface.

You can see Europa's cracked surface on the picture I have posted above. (This is actually a montage of images from NASA's Galileo spacecraft, with additional image processing by Professor Ted Stryk to bring out more detail.) One possibility is that the dark cracks we see are places where material from deeper inside the Moon (perhaps even from the liquid ocean) is seeping up toward the surface.

In the movie (see the poster below), future astronauts (from a private space company) go to Europa to search for evidence of life. The complex story is told by interweaving the view from cameras in their suits and in their cabins, with footage they recorded for sending back to Earth and interviews with the mission controllers, who eventually lose contact with the ship. What the surviving astronauts eventually find is far more than the micro-organisms scientists currently hope might exist deep under the ice of Europa.

The film, by Ecuadorian director Sebastian Cordero, is now available on DVD and various internet film services. If you enjoy somewhat complicated but scientifically reasonable space stories, I commend it to your attention. If not, spend a little time Googling other images of Europa and check out one of the strangest worlds with which we have the pleasure of sharing the solar system.

An Interview with the Father of the Search for Extra-terrestrial Intelligence

In 2012, during a weekend astronomy event (called SETICon II), I had the pleasure and privilege of doing a 45-minute on-stage interview with Frank Drake, the distinguished astronomer who did the first scientific experiment searching for evidence of intelligent life among the stars. The interview was videotaped at the time, but not released.

Now, to celebrate the beginning of the 30th year of the SETI Institute (the organization engaged in continuing that search), they have released the interview on YouTube and you can see it at:

Dr. Drake was the first President of the SETI Institute, and I have been a board member there since the beginning. We discuss both his career and his current thinking about the search, including his current view of the Drake Equation (a way of estimating the chances of intelligent life out there). He also reflects on a number of modern developments, including the discovery of numerous planets orbiting other stars and novel ways of searching for extra-terrestrial civilizations.

Searching for Intelligence Among the Stars & the Drake Equation

At the quarterly meeting of the Board of Trustees of the SETI Institute (to which I have the privilege to belong), I spent some time this week with Dr. Frank Drake, the astronomer who is the father of the science of the search for extra-terrestrial intelligence (SETI). Now over 80, Frank is still going strong and very much involved with the ongoing quest to find evidence that there are other intelligent species among the stars.  Today, 52 years after Frank made the first search for possible intelligent radio signals from other star systems, our technology for searching has become much more sophisticated, although funding for the searches is still sporadic.

The discovery of so many planets orbiting other stars is very encouraging to those who hope to find our counterparts out there.  The Kepler mission is showing that planets the size of Earth and planets in the habitable zones of their own stars are more common than most astronomers had dared to hope.

A few years ago, I had the pleasure of encouraging Frank (and his coauthor Dava Sobel) to update a historical summary of how he came up with the "Drake Equation." Not so much an equation as a way of making estimates, this formula (which you can see behind him in the photo) is now taught in many introductory astronomy classes. It helps us summarize our best knowledge of astronomy, biology and sociology to figure out how common our type of technological civilization might be in the Galaxy.

Thanks to the Astronomical Society of the Pacific (which published the column,) you can read the story of how he came up with the equation by going to:
