To be considered habitable,  exoplanets must orbit within a distance of their stars in which liquid  water can exist on the planet’s surface, receiving about as much  sunlight as Earth. “Most of these planets have a good  chance of being rocky, like Earth,” lead author Guillermo Torres of the  CfA said in a release. The discoveries of Kepler-438b and  Kepler-442b are the latest in several advancements scientists have made  to find signs of possible life in the universe. At a panel held last summer at NASA  headquarters in Washington, astronomers said they were “very close in  terms of technology and science to actually finding the other Earth.” That’s due in part to the Kepler  Space Telescope. The planet-hunting Kepler probe, launched in 2009,  finds planets by looking for dips in the brightness of a star as a  planet transits, or crosses, in front of that star.more about this news:<a href="http://www.risingbd.com/english/detailsnews.php?nssl=21143" target="_blank">http://www.risingbd.com/english/detailsnews.php?nssl=21143</a></blockquote>
