The prediction? Two stars, which are actually a contact binary (two stars that orbit each other, and also share a common atmosphere), about 1,800 light-years away in the Cygnus constellation, will merge and explode around 2022, and the event, which will lead to the formation of a red nova, will be visible to the naked eye when it occurs.
