Supernova Physicsterm was first used by Fritz Zwicky (1898–1974) and Walter Baade (1893–1960), two pioneers of the photographic era. Zwicky himself was, by all accounts, a somewhat abrasive character who once stated that the other astronomers at the Mount Wilson Observatory were “spherical bastards.” When asked to e

Supernovae in Our Neighborhoodernovae observed by human beings were ones within our own Milky Way Galaxy. This is hardly surprising as supernovae in external galaxies could not be discovered prior to the availability of powerful telescopes, and the true nature of them did not become apparent until the 20th century. With absolute

The Top 100 Extragalactic Supernovaeed amateur telescopes, are a relatively rare sight. However, the top 100 have all been within that category. Although I am excluding the superbright naked-eye Milky Way supernovae of historical times in this top 100 listing of Table 4.1, I feel the supernova 1987A in the Large Magellanic Cloud must

Supernovae as Visual Variable Starsther variable star. However, with even the brightest extragalactic supernovae in living memory being only 10th or 11th magnitude (excluding 1987A), the faint nature of these stars makes estimating their brightness a major challenge in all but the largest amateur telescopes. There is an additional pr
