Interstellar Geography: Finally Another M-Class Planet

Finally astronomy has begun to keep up with the legendary television show, Star Trek. For decades, one of television's strongest fan bases has been aware of "M-Class" (Earth-like) planets, on which carbon based, and often-human like life can exists. More often than not, such life did indeed exist in Star Trek. Until this past week, however, there was no hard evidence that our "M-Class" planet, Earth, had any company.

That changed with the recent discovery of, Keplar-22b, which was discovered by a NASA team using the Keplar Space Telescope. The planet is described as the first of similar size to earth that has been found in the "goldilocks zone" of habitability relative to its sun.

Of course, Star Trek had many more M-Class planets. But the race may be on. Researchers intend to use their results to extrapolate an estimate of the share of M-Class planets. Star Trek's nearly half-century lead in this inventory could be at risk.
