     Earth-sized planet orbits brown dwarf

    Extra-Solar PlanetsAn Earth-sized planet has been discovered in orbit around a small, cool star, but at the Sun-Earth distance. Thus, its surface must be very cold. If the planet has as much water as the Earth, it will be an ice-ball, but this cannot be determined from the observations.

     Seven Earths: One Sun

    Extra-Solar PlanetsNASA's Spitzer Space Telescope has revealed the first known system of seven Earth-size planets around a single star. Three of these planets are firmly located in the habitable zone, the area around the parent star where a rocky planet is most likely to have liquid water.

    The discovery sets a new record for greatest number of habitable-zone planets found around a single star outside our solar system. All of these seven planets could have liquid water -- key to life as we know it -- under the right atmospheric conditions, but the chances are highest with the three in the habitable zone.

     White dwarf shreds massive comet

    Extra-Solar PlanetsEvidence for the destruction of a massive comet-like body by a white dwarf star in the constellation of Bootes, 170ly distant, has been investigated by the Hubble Space Telescope and the Keck Telescope.

     Hubble Telescope used to solve an exoplanet mystery

    Extra-Solar PlanetsA survey of 10 hot, Jupiter-sized exoplanets conducted with NASA's Hubble and Spitzer space telescopes has led a team to solve a long-standing mystery — why some of these worlds seem to have less water than expected. The findings offer new insights into the wide range of planetary atmospheres in our galaxy and how planets are assembled.

     Massive "Super-Earth"

    Extra-Solar PlanetsA super-massive rocky planet has been found, some 560 light years from Earth. It currently carries the designation "Kepler 10c", and orbits its parent star every 45 days. The planet's diameter is estimated to be 18,000 miles, some 2.3 times as wide as Earth.
