    >Making use of the NACO instrument on ESO's Very Large Telescope, a German team of astronomers has taken an image of a companion to the T-Tauri star GQ Lupi. Comparing with archive data obtained with the HST and Subaru, the astronomers could confirm that the two objects move together in the sky. The companion, roughly 250 fainter than GQ Lupi A, is located at 100 AU from it.
    >
    >Additional NACO spectra show the companion to be a cool and small object. It is however still a matter of debate whether the newly found young sub-stellar companion is an exoplanet or a brown dwarf.
