Studying Thousands of New Worlds
Scientists studied the atmospheres of two exoplanets, planets orbiting another star, earlier this year. Both planets are roughly Earth-sized, with atmospheres a bit like the Solar System's terrestrial planets. Juno arrived at Jupiter last month, and will start its science mission in October. Finally, scientists found more than a thousand new planets; including more than a hundred Earth-sized ones. More at A Catholic Citizen in America .
