    We now believe there is at least one planet for every star in our galaxy. This could mean as many as 100 to 400 BILLION planets in our galaxy alone. This major finding from the Kepler mission, launched in 2009, reveals a crowded galaxy and the sheer magnitude of potential discoveries: strange worlds we never thought could exist, and maybe one day, a world like our own.

This super-Earth is 60% larger than our home world, but its year is only 20 days longer than ours. That places it quite comfortably in the habitable zone of a star very much like our sun.

The sizes of the exoplanets are represented by the size of each sphere.

    This plot shows data obtained from NASA's Spitzer Space Telescope and the Optical Gravitational Lensing Experiment, or OGLE, telescope located in Chile, during a "microlensing" event. Microlensing events occur when one star passes another, and the gravity of the foreground star causes the distant star's light to magnify and brighten. This magnification is evident in the plot, as both Spitzer and OGLE register an increase in the star's brightness.

Its star is much cooler and redder than our Sun. If plant life does exist on a planet like Kepler-186f, its photosynthesis could have been influenced by the star's red-wavelength photons, making for a color palette that's very different than the greens on Earth. This discovery was made by Kepler, NASA's planet hunting telescope.
