    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 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
