    "A mammoth sky survey led by University of Florida astronomers has uncovered seven planet-forming disks in
    clusters of young stars, doubling the number of such disks discovered and expanding the territory that might
    yield new planets."

    -- Astronomers show that low-mass stars in binary stars appear to behave like high-mass, evolved stars

    "Astronomers have found from their observations of over a dozen mass-losing stars in 'cataclysmic variables'
    that most of the secondary stars do not appear to be normal main sequence stars in terms of their apparent
    abundances. To various degrees, each star seems to have low to no carbon and other odd mixtures of
    elements such as sodium and calcium."

    "The Congress, Administration and NASA now must make important decisions about the future of space
    exploration," said Louis Friedman, Executive Director of the Planetary Society. "They will either choose an
    optimistic and positive direction for the human species -- outward -- or they will commit us to another 30 years
    bogged down in low Earth orbit."
