    Blog 36: The holiday wreath galaxy
    NASA charmingly described galaxy Messier 74 back in December 2011 when it published a Hubble Space Telescope view of it: "Resembling festive lights on a holiday wreath, this ... image of the nearby spiral galaxy M74 is an iconic reminder of the impending season. Bright knots of glowing gas light up the spiral arms, indicating a rich environment of star formation." M 74, a relatively close spiral, is well placed for telescopic viewing in the Fall through early Winter. When members of the Salt

A star is a perfect example of how to go into that good night. If larger than about eight times the Sun's mass, it will explode as a supernova, for a few days or weeks shining brighter than the entire galaxy that hosts it. If in the class of the nuclear furnace at the center of our solar

    Blog 33: The colors of stars
    Take a mental trip to a dark site in the western Utah desert, accompanied by a friend who's an experienced star guide. This is June 6, 2019, on a clear, cool moonless midnight. "Want to see something 10,000 times as bright as the sun?" the guide asks. "Sure!" "Look directly south," and you peer past the ragged silhouettes of sagebrush toward the glowing bulge of the Milky Way. It’s always a lovely sight, especially now, when it looks like a tilted flying saucer with one edge continuing up and
