The 12 Lightyear Boundary
Researchers working with data from the Kepler Space Telescope have arrived at an incredibly interesting figure: 1 in 5 stars have at least one earthlike planet orbiting within its habitable zone. Or as one astronomer put it
“What this means is, when you look up at the thousands of stars in the night sky, the nearest sun-like star with an Earth-size planet in its habitable zone is probably only 12 light years away and can be seen with the naked eye.” – Dr. Andrew Howard
Imagine that – if one considers “island hopping” from one system to the next in search of life, the journey has now been shrunk to 12 lightyears. With continued technological advancement, we can easily bridge such distances. Why do we drag our feet?
