Results from satellite observatory
140 Earth-like planets already found
"Planets like Earth are out there"
SCIENTISTS are celebrating the discovery of more than 700 suspected new planets - including up to 140 similar in size to Earth - in just six weeks of using a powerful new space observatory.
Early results from NASA’s Kepler Mission, a small satellite observing deep space, suggested planets like Earth were far more common than previously thought.
Past discoveries suggested most planets outside our solar system were gas giants such as Jupiter and Saturn - but the new evidence tipped the balance in favour of solid worlds.
Astronomers said the discovery meant the chances of eventually finding truly Earth-like planets capable of sustaining life rose sharply.
NASA so far formally announced only five new exoplanets - those outside our solar system - from the mission because its scientists were still analysing Kepler’s finds to confirm they were actually planets.
“The figures suggest our galaxy, the Milky Way (which has more than 100 billion stars) will contain 100 million habitable planets and soon we will be identifying the first of them,” Dimitar Sasselov, professor of astronomy at Harvard University and a scientist on the Kepler Mission said.
"There is a lot more work we need to do with this, but the statistical result is loud and clear and it is that planets like our own Earth are out there."
Very interesting article, but I think it's a little premature for them to be announcing a figure on the numbers of terrestrial worlds...or more specifically Earth like planets...that they'll find. That should wait until they have a better grip on just how many they do find, and from more than just one survey mission like Kepler. Although, the results are still very important in our understanding of what's out there.
6 weeks....Kepler's been up longer than that. Anyone remember when it was launched???. I think it was in March, wasn't it??
Thanks Michael...I knew it'd been up for awhile...haven't kept up with the mission. Sounds like that what it was...the release of the first 6 weeks worth of data.
