Kepler 10-b, a new rocky Earth-like planet found by NASA, could
be the missing link between Earth and the rest of the galaxy by
being the first possible habitable planet found in the universe.
Unique to other known planets, Kepler 10-b is made of mostly
rock, whereas most planets consist of gas or ice. Just 40%
larger than Earth, it is the smallest planet besides Earth
found. Because of its characteristics, it is a crucial piece in
the search for possible life. Astronomers have long speculated
that such planets do exist, but Kepler wasn’t discovered until a
telescope in Hawaii sensed its gravitational pull. Read the full
report by TIME’s Michael Lemonick.
