This Week's Sci-light!

Feel like moving?  Well there might be a destination.  The adventure to get there might be something similar to the marine turned Avatar in the movie bearing that same name.  Then again, perhaps we'll figure out how to travel "Star Trek style."  Beam me up, Scotty!

Welcome to Kepler 62f.  (That's as good a name as "earth!")  How did this world get it's name--from the NASA Kepler space craft that discovered it.  I should actually say "them" as there are 5 planets circling this star that is somewhat dimmer than our sun.  Kepler 62f is special because it is one of two planets that seem made of rock and may have oceans.  Intrigued?  Read Dennis Overbye's  story "Two Promising Planets to Live, 1,200 Light-Years from Earth" in the New York Times.

There's history here, too.  Johannes Kepler born in 1571 to a poor family in Weil der Stadt, Württemberg.  He was a sickly child but his intelligence earned him a scholarship to attend University of Tübingen where he was delighted with the work of Copernicus.  The history and NASA connection you can read.   Eventually and recently, Kepler met Einstein by showing gravity bending as an extremely dense dwarf star crosses in front of a red star. 

By the way, my job is not to explain all of this to you--simply to wet your apetite for it.  History meets science meets science fiction today.  So, here's the personal question:  Where are you going?  The universe is an expansive place with concepts smaller and larger than the mind can grasp or imagine.  But isn't it fun to learn more and keep trying!
