See a supernova explosion in a distant galaxy over 50 million light years away.
Berto Monard witnessed Supernova 2015F in spiral galaxy NGC 2442 in March 2015, although the actual event happened 50 million years ago, long before human beings inhabited planet Earth.
Supernovae like this produce so much light energy they can briefly out shine the accumulated light from the entire galaxy. For this reason they can be witnessed even with moderately sized back garden telescopes, if you’re lucky enough to be pointing in the right direction at the right time!
