The explosion of a supernova very close to us has been detected, but don't worry, it poses a risk to the earth since the explosion occurred in another galaxy, in the one known as the pinwheel galaxy or M101 located 21 million light years away. which, is a great distance, but on a cosmic scale it is quite close.
