Planet Nine - Astronomers Find Evidence of a Real Ninth Planet in Our Solar System

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…

In astronomers discovered a star composed entirely of diamond, measuring km across and 10 billion trillion trillion carats. 50 light years from Earth, the diamond star is classified as a crystallized white dwarf, the hot core that remains after

Double suns! A new planet that orbits two suns has been discovered using our Kepler Space Telescope. Planets that orbit two stars are known as circumbinary planets. The stars here are similar to the sun, with one slightly larger than our home star and the other slightly smaller. The planet has a mass and radius nearly identical to that of Jupiter, making it the largest transiting circumbinary planet ever found.

Mars is the fourth planet from the Sun in our Solar System. Mars has a thin atmosphere and its red color comes from iron oxide in the soil.

A rover headed for the red planet will perform an unprecedented search for rocky remnants of dead Martians—so where should we send it?

If there's intelligent life within 100 light years of our planet, it's likely they've already gotten an earful (or antennae-ful, or whatever analogous organ-ful) of our radio and TV shows, which have been leaking into space since we first started broadcasting them. Scientists have also sent messages, images and even phonograph records into space in order to show E.T. that humanity isn't just about 'The Lone Ranger' and 'I Love Lucy.'
