NASA Spitzer Space Telescope Earth Exoplanet
NASA’s Spitzer Space Telescope data gives us a glimpse of the surface of a rocky, Earth-sized exoplanet outside of our own solar system orbiting the most common type of star in the galaxy, for the first time. The planet’s surface most closely resemble that of Earth’s Moon or Mercury, as in it has little to no atmosphere and could be covered in the same cooled volcanic material found in the dark areas of the lunar surface.
