Using NASA’s Kepler spacecraft, astronomers are beginning to find Earth-sized planets orbiting distant stars. A new analysis of Kepler data shows that about 17% of stars have an Earth-sized planet in an orbit closer than Mercury. Since the Milky Way has about 100 billion stars, there are at least 17 billion Earth-sized worlds out there. The odds are that at least ONE of these harbors intelligent life.

Altogether, researchers have found that 50% of stars have a planet of Earth-size or larger in a close orbit. By adding larger planets, which have been detected in wider orbits up to the orbital distance of the Earth, this number reaches 70%. In other words, practically all Sun-like stars have planets.

Despite widespread knowledge that a vaccine is the best way to reduce the chances of catching and spreading the flu, even three of the four main anchors on a popular morning TV show recently admitted they had not gotten a flu shot (until they did so live on the air).
