As I mentioned in a previous blog post, this year marks the 50th Anniversary of the SETI program -- the Search for Extraterrestrial Intelligence. This is why we've seen far more than the usual number of articles, interviews, and new books and their corresponding reviews on the subject.
In fact, not too many months ago -- April 25, to be exact -- the UK's Sunday Times Online ran an article on Stephen W. Hawking's (pictured above) new Discovery Channel documentary, with the following quote from the physicist: "The aliens are out there, and Earth had better watch out." Now, in a new audio recording with Big Think, Professor Hawking warns us that humanity's survival depends on inhabiting the stars: "I believe that the long-term future of the human race must be in space. It will be difficult enough to avoid disaster on planet Earth in the next hundred years, let alone the next thousand, or million. The human race shouldn't have all its eggs in one basket, or on one planet. Let's hope we can avoid dropping the basket until we have spread the load." And, of course, while we're at it, we need to be wary of ET! The Big Think piece is quite compelling; Hawking states that he is an optimist, but his outlook for the human race is very bleak. And there are more than 50 Comments to the article, some as intriguing as (if not more so than) the article itself.
This past weekend, the SETI Institute in Mountain View, California, hosted SETIcon, a convention that brought together representatives from science and research (Frank Drake), space exploration (Astronaut Rusty Schweickart), television & media (producer Andre Bormanis, actor John Billingsley), literature (authors Mary Roach & Robert J. Sawyer), music (Mickey Hart), and many others, and was open to the public. Speaking at the convention, Seth Shostak, senior astronomer at the SETI Institute, said: "I actually think the chances that we'll find ET are pretty good....Young people in the audience, I think there's a really good chance you're going to see this happen."

Of course the big questions continue to be: "How will we discover ET?" and/or "In what form(s) will we discover ET?" -- which was touched on in my previous blog on "50 Years of SETI" -- but if you haven't figured out where I'm headed with this then you haven't been reading my blog regularly.
