    Blog 34: Planetary nebulas ... and Baby!
    Do not go gentle into that good night, Old age should burn and rave at close of day; Rage, rage against the dying of the light. -- First stanza of Dylan Thomas' "Do Not Go Gentle into that Good Night," 1951. 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

    Blog 31: Kip Thorne
    Professor Kip S. Thorne, the newly minted Nobel laureate, will never forget his feelings when he learned the observatory that was the focus of his career had registered a disturbance caused by two black holes merging 1.3 billion light-years away. The detection was by the miles-long instruments making up the Laser Interferometer Gravitational-wave Observatory (LIGO), which are located in Hanford, WA, and Livingston, LA. By the time they reached Earth, the brief jiggles in the fabric of space

    Blog 30: Waves of discoveries
    One of the greatest astronomical discoveries was the physical detection of gravitational waves emanating from merging black holes in far-off galaxies. Predicted by Albert Einstein in 1916 as a consequence of his Special and General Theories of Relativity and deduced in 1974 through studies of orbiting pulsar stars, they never were recorded directly until Sept. 14, 2015. The latest announcement of gravitational wave discoveries came on Sept. 27, a detection made on Aug. 14 by the twin Laser
