Several supernovae have been observed from Earth throughout history. Here are a few notable examples:
SN 1054: This supernova occurred in the year 1054 and was observed by Chinese, Japanese, and Middle Eastern astronomers. It resulted in the creation of the Crab Nebula in the constellation Taurus.
SN 1572 (Tycho's Supernova): This supernova was discovered by astronomer Tycho Brahe in November 1572. It appeared in the constellation Cassiopeia and briefly outshone Venus in brightness.
SN 1604 (Kepler's Supernova): Observed by Johannes Kepler in October 1604, this supernova was visible to the naked eye for several weeks. It was located in the constellation Ophiuchus.
SN 1987A: This supernova occurred in the Large Magellanic Cloud, a satellite galaxy of the Milky Way. It was discovered on February 24, 1987, making it one of the closest supernovae observed in modern times.
These are just a few examples of supernovae visible from Earth throughout history. It's worth noting that modern telescopes and observational techniques have significantly increased our ability to detect and study supernovae in distant galaxies.
