18 Quadrillion kms away from us there is a binary star system, KIC 9832227 where two stars are orbiting each other. 7 years ago in 2013, scientists saw changes in its brightness. So they decided to study it further more detailed study concluded that these two stars are rapidly coming closer and they are about to merge into each other.
Just 2 years from now, in 2022, these binary stars will eventually merge and cause a massive supernova explosion. This explosion will form a giant Red Nova. This Red Nova will be so big that we would be able to see it without any instrument.
