This illustration released by the University of Santa Cruz shows a super-Earth type planet, named GJ1214b, left, in the atmosphere. For the first time astronomers probed the atmosphere of this planet by observing chemical signatures imprinted on light from the planet's host star as it filtered through the planet's atmosphere. GJ1214b is about 2.6 times Earth's radius, but about 6.5 times its mass, and it circles a red dwarf star, top right. (AP Photo/University of California at Santa Cruz, Paul A. Kempton)  NO SALES.
