Kirshner says he has worked with supernovae for the past 17 years, ever since he started his graduate work in California. But even as a junior concentrator in Harvard's undergraduate Astronomy Department, Kirshner decided to focus on his present specialty, when he took a tutorial on the Crab Nebula, a supernova remnant...
...remember when I showed up at Cal Teach the first day, they asked me what I wanted to work on. I said, `I did some work on Crab Nebula, do you have any work on supernovae?' Some of these things are sort of thrust upon...
...time to go to bed." But before turning in, he made up his mind to develop the last photographic plate. Lifting the plate from the developing tank, he scrutinized it, then stopped short. There, near a feature within the LMC known as 30 Doradus, or the Tarantula nebula, was an unfamiliar bright spot...
...have intense magnetic fields generating precisely spaced electromagnetic pulses that can be picked up by radio telescopes. Some 440 pulsars have been discovered so far, all of them thought to be remnants of Type II supernovas. The youngest found to date sits right at the center of the Crab nebula, site of the great supernova...
...July 4, 1054, which suddenly blazed in the constellation Taurus, near Orion, that is perhaps most significant to present-day astronomers. It exploded only about 6,000 light-years away and left behind the slowly writhing, gradually expanding and delicately beautiful cloud of glowing gas known as the Crab nebula. Studies of the structure and dynamics of the Crab have provided modern astronomers with important insights into supernova explosions...
