Kepler-186f ~ The first known Earth-size planet to lie within the habitable zone of a star beyond the Sun. Discovered using data from the prolific planet-hunting Kepler spacecraft, the distant world orbits its parent star, a cool, dim, M dwarf star about half the size and mass of the Sun, some 500 light-years away from us, in the constellation Cygnus. While the size and orbit of Kepler-186f are known, its mass and composition are not, and can't be determined by Kepler's transit technique…
Uranus is the third largest planet in our Solar System. Uranus has nine major rings and 27 known moons. This image, taken by the Hubble Space Telescope in infrared reveals cloud structures not normally visible. Methane gas in the upper atmosphere absorbs red light, giving the planet its blue-green color. Uranus is spinning on its side, probably because of a collision with a large object early in the Solar System's
