    Blog 71: Bennu
    The OSIRIS-REx spacecraft arrived at the asteroid called Bennu on Dec. 3, and already has made scientific discoveries: Bennu has few craters, boulders litter the surface like chocolate in a chocolate chip cookie, and the asteroid shows signs of the presence of water at some time in the past. NASA’s ludicrously-named spacecraft -- the acronym stands for Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer -- cruised past the asteroid, having traveling 1.2 billion

    Blog 68: The Pleiades' 3,000 sisters
    The lovely open star cluster, the Pleiades, has been called the Seven Sisters since antiquity. But nobody sees seven stars in this showpiece of the late autumn and winter, not by unaided eyeball and certainly not by telescope. Like a tiny kite of bright points, in November the Pleiades are visible in the east after sunset and are easily seen until dawn. They lodge on the shoulder of the constellation Taurus the bull.
