Stellar explosion in Earth’s proximity

When the brightness of the star Betelgeuse dropped dramatically a few months ago, some observers suspected an impending supernova – a stellar explosion that could also cause damage on Earth. While Betelgeuse has returned to normal, physicists from the Technical University of Munich (TUM) have found evidence of a supernova that exploded near the Earth around 2.5 million years ago.

Discovery of a nearby supernova 2.5 million years ago boosting cosmic rays may lend credence to Svensmark’s cosmic rays modulate clouds on Earth theory.
