Two "Water World" planets orbit the star Kepler-62. This five-planet system has two worlds in the habitable zone — the distance from their star at which they receive enough light and warmth that liquid water could theoretically exist on their surfaces. Modelling by researchers at the Harvard-Smithsonian Center for Astrophysics (CfA) suggests that both planets are water worlds, their surfaces completely covered by a global ocean with no land in sight.
Kepler-62 is a type K star slightly smaller and cooler than our sun. The two water worlds, designated Kepler-62e and -62f, orbit the star every 122 and 267 days, respectively.
They were found by NASA’s Kepler spacecraft, which detects planets that transit, or cross the face of, their host star. Measuring a transit tells astronomers the size of the planet relative to its star.

I'm always amazed by what is now discovered.
Also, how they find these things!
Always comes down to the quality of the measurements.
And the numbers are growing:
A total of 908 such planets (in 700 planetary systems, including 140 multiple planetary systems) have been identified as of 6 July 2013. The Kepler mission has detected over 18,000 additional transit events, including 262 that may be habitable planets. In the Milky Way galaxy, it is expected that there are many billions of planets (at least one planet, on average, orbiting around each star, resulting in 100–400 billion exoplanets)
Of all those planets how many are older than our planetary system.
We were created first.
DUH! Of course!
That's why WE discover them, and not the reverse.
Haha! Of course bitches!
As far as I can tell, there would be no universe without us, or at least no one talking shit about it. =)
What is amazing with the increasing number of planets discovered, is that they are exclusively ones that happen to cross our line of sight to their stars. All the others living on an ecliptic plane that is slightly ajar, we won't be counting anytime soon.
And now this: A Deep Blue Dot!
The planet currently known as HD 189733b is one of the closest planets astronomers have discovered outside of our own solar system – only 63 light years away. It was first discovered in 2005, when French astronomers observed it moving in front of its star. And now, astronomers observing the planet with the Hubble Space Telescope have learned something else about it – it’s blue.
Don’t get too excited, though – it’s not blue because it’s covered with water. HD 189733b is bigger than Jupiter and is so close to its star that it’s year is only 2.2 days. Its temperature gets as high as 2,000 degrees. On one side, anyway. Since it’s so close to its star (about 2 million miles away), the planet is tidally locked – meaning only one side of the planet faces the star, period.
