Supernova remnants are vital to our understanding of Stellar Nucleosynthesis. After a supernova detonates, the central neutron star powers the light of the nebula with Synchrotron radiation and shock heating. We see examples of this in the Veil Nebula, Tycho's 1572 Supernova, and Kepler's Supernova from 1604. The best studied of the SNRs is the Crab Nebula. Now we look in detail at the results of the labors of the most massive stars in the cosmos, and some of the most beautiful sights in a telescope. The remnants of supernova explosions. This is part of my complete intro Astronomy class that I taught at Willam Paterson University and CUNY Hunter.
