    Discovery of a Giant Stellar Tidal Stream Around The Disk Galaxy NGC 4013
    We report the discovery of a giant, looplike stellar structure around the edge-on spiral galaxy NGC 4013. This arcing feature extends 6' (~26 kpc in projected...

    Discovery of a Metal-poor Field Giant with a Globular Cluster Second-generation Abundance Pattern
    We report on the detection, from observations obtained with the Apache Point Observatory Galactic Evolution Experiment spectroscopic survey, of a metal-poor (...

    Discovery of a Protocluster Core Associated with an Enormous Lya Nebula at z = 2.3
    The MAMMOTH-1 nebula at z = 2.317 is an enormous Lyα nebula (ELAN) extending to a ~440 kpc scale at the center of the extreme galaxy overdensity BOSS 1441. In...

    Discovery of a Second Transient Low-Mass X-ray Binary in the Globular Cluster Ngc 6440
    We have discovered a new transient low-mass X-ray binary, NGC 6440 X-2, with Chandra/ACIS, RXTE/PCA, and Swift/XRT observations of the globular cluster NGC 6440...

    Discovery of a Very Low Mass Binary with the Hubble Space TelescopeNear-Infrared Camera and Multiobject Spectrometer
    Hubble Space Telescope Near-Infrared Camera and Multiobject Spectrometer (NICMOS) observations of six brown dwarf candidates in the Pleiades open cluster are...

    Discovery of a Wide Companion near the Deuterium-burning Mass Limit in the Upper Scorpius Association
    We present the discovery of a companion near the deuterium-burning mass limit located at a very wide distance, at an angular separation of 4.6''+/-0.1''...

    Discovery of a Young Planetary Mass Companion to the Nearby M Dwarf VHS J125601.92-125723.9
    In a search for common proper motion companions using the VISTA Hemisphere Survey (VHS) and the 2MASS catalogs we have identified a very red (J-{{K}s}=2.47 mag)...

    Discovery of an Active Galactic Nucleus Driven Molecular Outflow in the Local Early-type Galaxy NGC 1266
    We report the discovery of a powerful molecular wind from the nucleus of the non-interacting nearby S0 field galaxy NGC 1266. The single-dish CO profile...

    Discovery of an Extraordinarily Massive Cluster of Red Supergiants
    We report the discovery of an extraordinarily massive young cluster of stars in the Galaxy, having an inferred total initial cluster mass comparable to the most...
