Scientists: We're 'very close' to finding another Earth
Abstract
A news from NASA for the discovery of the second earth, describing the similar characteristic between earth - life/creature phenomenon, physical properties e.t.c.
My summary
Scientists from NASA headquarters announced that they discovered a planet through a picture, launched in 2009, by Kepler space telescope.This "Second earth","Kepler-186f" locates in a habitat zone which orbit a star.Thus, there might be liquid water exits on its surface. One of the most special and important information is the size of Kepler-186f is only 40% larger than earth. Though the mass and density can't be measured precisely, this is the first time that NASA detect the Earth-size planet orbit around stars like our sun. This indicates there might be living things appearance or a suitable condition for creature. The other information is the continued missions of Earth-size planet detecting will use a new telescope equipment called James Webb space telescope launch in 2018 with newer and higher performance. Hope we are not alone in the universe.
