Cosmic Journeys - The Search for Earth-like Planets
Δημοσιεύθηκε στις 24 Μαρ 2014
Get the latest from the
planet-hunting frontier. Find out what we are learning about our place
in the cosmos from the search for earth-like planets.
This
journey started tens of thousands of years ago, when humans began to fan
out across the planet, following unknown pathways, crossing unmeasured
distances. We traced coastlines, and sailed uncertain seas. We crossed
ocean straits drained by an ice age.
Into every corner of Earth
we ventured, looking for places to put down our roots, to raise our
families, or just to see what was there. Today, it's the final frontier
that fires our imaginations. With so many stars in our galaxy, we make a
simple extrapolation, that the cosmos must be filled with worlds like
ours, with life, even intelligent life.
For four years, the
historic planet hunting mission, Kepler, starred at a group of 150,000
stars located in a region extending three thousand light years away from
earth.
The data collected by this spacecraft has brought a
turning point in the long search for other planets like earth. Is ours
one of countless life-bearing worlds strewn about the galaxy; or is it a
rare garden of eden in a barren universe?
