SETI Shutdown & Aliens - Jill Tarter Interview

"We’re doing everything we possibly can to bring it out of hibernation. But that, you know, that requires new funding.
We’re talking with the Air Force, and we’re hopeful for that. But we also need the public to step up and support SETI research, to keep that on an even keel. This unfortunate situation, coming at just the wrong time, when we were just beginning a two-year search of these Kepler worlds — we hope people understand the irony of that.
Before Kepler launched, we knew about a couple of hundred exoplanets. Most of those were big or right next to their stars. Not likely to be habitable. The Kepler worlds are different. There are 68 of them that are about the same size as Earth, of which it’s calculated that 54 may be in the “Goldilocks” habitable zone. And there’s 1,235 of them altogether, which [extrapolated] gives us the statistic that we can expect 50 billion planets in the galaxy, and 500 million of those are likely to be habitable.
The Kepler results have changed the way we can do our research. We can now point where we know there are likely to be good planet candidates. That’s a change. This is a fantastic new bounty of potential and information. "
