In 2013, the Kepler telescope had to stop planet hunting due to the failure of two reaction wheels. But that doesn’t mean the telescope is completely out of commission. In fact, using a new technique that takes advantage of the solar wind, the Kepler telescope just discovered its first planet, a planet that could be similar to Earth but over twice the size.

How many habitable planets?
Looking at the latest analysis of the data from the Kepler Spacecraft the number of habitable planets are potentially now one in five.
Analysis by UC Berkeley and University of Hawaii astronomers shows that one in five sun-like stars are potentially habitable.
“When you look up at the thousands of stars in the night sky, the nearest sun-like star with an Earth-size planet in its habitable zone is probably only 12 light years away and can be seen with the naked eye. That is amazing,” said UC Berkeley graduate student Erik Petigura, who led the analysis of the Kepler data.
When the James Webb Space Telescope is launched, hopefully in 2018, it should be able to look at these habitable plants and see in even more detail the surface of the planets. One of the four James Webb science themes is Planetary Systems and the Origins of Life.
It’s just a matter if time until we discover that first other ‘Blue Marble.’
