Two years ago, almost to the day, I blogged about NASA launching the Kepler telescope after they calculated that there are probably a hundred billion Earth-sized planets in our galaxy alone. And now we have some results. Kepler has discovered 1,235 planets including 5 Earth-sized planets in their star's Goldilocks zone - the zone around a star in which water is liquid and life as we know it may be possible.
Kepler has also found six confirmed planets orbiting a sun-like star, Kepler-11. This is the largest group of transiting planets orbiting a single star yet discovered outside our solar system. The Kepler team reckon that one star in two has a planetary system.
The Daily Telegraph has published this photograph...
...which they amusingly claim is a photo taken by the Kepler telescope.
Of course there's no chance it's a real picture from Kepler; planets don't line up like that to be snapped in a single photo, and anyway those planets are far too large relative to the star.
What we need now is an even bigger telescope to peer closely at the 5 Earth-like planets to see what's going on down there. At the moment their presence is being inferred by a dimming of the parent star as the planet passes in front of it. But with a bigger telescope we could resolve the planets themselves. Will there be oceans? Greenery? Perhaps even a large herd of migratory animals could be made out! We live in interesting times for astronomers.
