Melissa Weiss/CfA/Harvard Scientists say they have detected promising signs that a planet orbiting a star 49 light-years from Earth could have an atmosphere, making it potentially suitable for life. Called LHS 1140b, the object is about five times the mass of our planet, or a “ super-Earth .” This planet orbits around its star in the “ Goldilocks zone ,” also known as the habitable zone, meaning its surface temperature is not too hot or too cold for liquid water to exist. “We believe it is also predominantly a rocky planet, based on its mass and its radius measurements, which gives us a density estimate,” said Collin Cherubim, a planetary scientist and lead author of a paper on the finding, published July 16 in the journal Science. “It appears to be consistent with Earth, m...

That is the conclusion of a decades-long study that has recorded - and filmed - hundreds of the world's biggest whales in...
