Astronomers have discovered four new planets in a week's time, an exciting end-of-summer flurry that signals a sharper era in the hunt for new worlds.    While none of these new bodies would be mistaken as Earth's twin, some appear to be noticeably smaller and more solid - more like Earth and Mars - than the gargantuan, gaseous giants identified before...

U.S. astronomers say the Hubble Space Telescope has allowed them to study for the first time the atmospheric structure of a planet orbiting another star.  Hubble discovered a dense upper layer of hot hydrogen gas where the super-hot planet's atmosphere is bleeding into space.
