This is not fake news. It was reported on NPR.
Scientists predict that a pair of stars in the constellation Cygnus will collide in 2022, give or take a year, creating an explosion in the night sky so bright that it will be visible to the naked eye.
If it happens, it would be the first time such an event was predicted by scientists.
Calvin College professor Larry Molnar and his team said in a statement that two stars are orbiting each other now and “share a common atmosphere, like two peanuts sharing a single shell.”
They predict those two stars, jointly called KIC 9832227, will eventually “merge and explode … at which time the star will increase its brightness ten thousand fold, becoming one of the brighter stars in the heavens for a time.” That extra-bright star is called a red nova. They recently presented their research at a meeting of the American Astronomical Society in Grapevine, Texas.
The following was an explanation on the Daily Beast.
For six months this new star will—to the naked eye—be the brightest in the heavens. Given that this is the first time that people will be able to witness a moment like this without technology, it’s a significant event in human history, but it may be much more than that. According to one rabbi, this new star is a sign of the coming of the Messiah.
Rabbi Yosef Berger, a rabbi of King David’s Tomb on Mount Zion, has proposed that the star is a fulfillment of a Biblical prophecy from the book of Numbers, in which a star precedes the arrival of an important military leader: “a star shall come out of Jacob, and a scepter shall rise out of Israel; it shall crush the borderlands of Moab, and the territory of all the Sethites” (NRSV Num 24:17)
