Goldilocks Zone

The Goldilocks zone – not too hot, not too cold, but just right.  Goldilocks, also known as “habitable zone”, is that sweet planetary orbit Earth holds in our solar system. Science searches the cosmos for planets capable of supporting life as we know it. Star systems with Earth-like planets positioned not too far, not too close,  just maybe at a perfect distance to have liquid water and harbor life.

On January 6, astronomers from the Harvard-Smithsonian Center announced 8 new Goldilocks planets. Two stand out as the most promising Earth-like discoveries to date. Kepler 438b and Kepler 422b orbit red dwarf stars smaller and cooler than our sun. 438b is 12 percent larger than Earth, orbits its sun once every 35 days, has a 70% chance of being rocky, and resides 470 light years from home. 422b, 1,100 light years away, is a third larger than Earth, orbits its sun every 112 days with a 60% chance of a rocky surface.

Hard as it is to ponder seemingly impossible distance and probability of life, it’s only a matter of time before science announces extraterrestrial life.

  1. It is one of those scientific questions that will be answered without going anywhere near such a planet. Somebody will figure out the precise mix of ingredients, collect data that will inexorably lead to the conclusion that life is not only possible elsewhere but that it is unavoidable under such conditions. They will then figure out an experiment that will look for a signature profile that even the most disbelieving scientist will accept as proof. They will find it and science will then write QED.

    And religion will rejoice in even greater Gods that create life elsewhere as well.
