It'll take over 100 years for Kepler to find

..an earth like planet.

'We'll have to be really lucky to decipher an Earth-like planet's atmosphere during a transit event so that we can tell it is Earth-like,' said Kaltenegger. 'We will need to add up many transits to do so — hundreds of them, even for stars as close as 20 light-years away.'"

To put it simple, hundreds of observations of transits means hundreds of years of observation if it has about one year orbit around the star, like earth does. This means we are not going to celebrate finding an earth-like planet anytime soon.

Sorry to spoil the fun for everybody, I was hoping for some fast results as well. They can only find a planet the SIZE of earth in three years, like they said. They can't figure out its atmosphere in that time, there just is no way that we know of. Hopefully they will find a way.

What do you think?

Just because earth has a orbit time of 1 year; does not mean that the other planet orbiting around a star in the goldilocks zone, should have the same time period. Based on the size of the star, the time period of the planet may be smaller or larger. And we are looking for the smaller one.
