Kepler's Supernova (SN 1572)

Kepler's Supernova, also known as SN 1572, was a bright stellar explosion observed in 1572 by astronomer Johannes Kepler. It occurred when a massive star exhausted its fuel and collapsed, then exploded in a supernova, releasing an enormous amount of light that temporarily outshined entire galaxies. This explosion created a glowing remnant of gas and dust expanding into space. Kepler’s detailed observations helped scientists understand the life cycles of stars and provided evidence that such supernovae could appear in our galaxy long after the ancient supernovae observed by earlier astronomers.
