    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. Bruce McClure, in an article posted by EarthSky.org, says November is often

    Blog 64: Nature's laws
    During my years as a newspaper science reporter, I sometimes asked astronomers and physicists a question that still puzzles me: natural laws govern everything from radiation released by atomic bombs to the combinations of molecules, from galaxy shapes to ripples in a pond -- were these rules present at the time of the Big Bang, before a single atom had formed? That is, do the rules predate the objects they govern? A saying by the rebel priest John Ball (who lived from about 1338 until his
