    • Exocomets that circle distant stars might be more common than previously thought. (NASA/Lynette Cook)
    • Researchers have identified a new spine-like structure of our Milky Way galaxy -- a long, dense tendril of dust and gas. (NASA/JPL/SSC)
    • The Milky Way’s 'backbone' structure contains about 100,000 stars' worth of gas and dust. (Jarret et al. 2012 Wise Enhanced Resolution Galaxy Atlas)
    • NASA’s Hubble Space Telescope captured this image of the 10-billion year old supernova SCP-0401. (Space Telescope Science Institute)
    • The installation of Hubble’s new Wide Field Camera 3 in 2009 led to confirmation of Supernova SCP-0401’s age. (NASA)
    • Hubble Space Telescope/NICMOS near-infrared image of a black hole at the center of the Milky Way galaxy (NASA/STScI)
    • A University of Arizona-led team of astronomers has discovered inner asteroid belts and outer comet-filled belts similar to the arrangement found in our solar system around nearby stars Vega and Fomalhaut. (NASA/JPL-Caltech)
    • Newly released NASA Hubble Space Telescope images of a vast debris disk encircling the nearby star Fomalhaut and a mysterious planet circling it may provide forensic evidence of a titanic planetary disruption in the system. (NASA, ESA)
    • The accelerating expansion of the galaxies observed by Hubble may conform more to Albert Einstein’s “cosmological constant” than a popular alternative theory of dark energy. (NASA; ESA)
    • Researchers using the Stratospheric Observatory for Infrared Astronomy (SOFIA) have captured new images of a ring of gas and dust seven light-years in diameter surrounding the supermassive black hole at the center of the Milky Way. (NASA/SOFIA/FORCAST tea
    • NASA's Spitzer and Hubble space telescopes have probed the atmosphere of a brown dwarf, creating the most detailed 'weather map' yet for this class of cool, star-like orbs. (NASA/JPL-Caltech)
    • An artist’s conception of ice in a liquid hydrocarbon sea on Saturn's moon Titan. (NASA/JPL-Caltech/USGS)
    • NASA's Nuclear Spectroscopic Telescope Array (NuStar) catches black holes in a galaxy web. (SA/JPL-Caltech/DS)
    • This infrared image from the European Southern Observatory’s VISTA telescope shows the globular cluster 47 Tucanae in sharp detail, revealing millions of stars. (ESO/M.-R. Cioni/VISTA Magellanic Cloud Survey)
    • In their search for habitable worlds, astronomers have started to consider exomoons -- satellites orbiting planets in distant solar systems -- which could be just as likely to support life as exoplanets. (R. Heller, AIP)

    Topics at the American Astronomical Society Meeting

    Published January 10, 2013

    Exoplanets, X-ray astronomy, and extragalactic outbursts were discussed at the meeting of the American Astronomical Society in Long Beach, California this week. Nearly 3,000 astronomers, educators and students and journalists attended some 2,000 sessions on outer world phenomena.
