NASA Discovers First Earth-Size Planets Around an Alien Star: VIDEO

Planets

Probably too hot for life as we would recognize it, but exciting nonetheless:

NASA's Kepler mission discovered the first Earth-size planets around a star beyond our own. The system is jam-packed with five planets, all circling within a distance roughly equivalent to Mercury's orbit in our solar system.

The two Earth-size planets, which are presumably rocky, are Kepler-20e and Kepler-20f, and the three larger gas planets are Kepler-20b, Kepler-20c and Kepler-20d. The arrangement of the planets from the closest to its star to the farthest is: b, e, c, f and d, with the ordering of the letters reflecting the time at which the planets were initially discovered.

  1. to think that my high school and college science teachers once poopooed the notion of other life out there by insisting no evidence showed even other stars that had ANY planets.

    paralleled the blind devaluing of anything but a polar hetero orientation, with a blind and misapplied notion of darwinism.

    to honesty in discovery and life, y'all. even if most people blindly and violently cling to what they believe they "know."

  2. A 19 day year. A 6 day year. Sheesh.
