Two colliding stars

Two stars may collide into a stunning “red nova” in 2022 (or a few months earlier, most probably between September 2021 and September 2022), and for a few weeks become one of the brightest objects in Earth’s night sky, scientists predict. When two stars merge, they increase in brightness 10 thousandfold.

The pair located about 1800 light-years away and known as KIC 9832227, a contact binary star system in the constellation of Cygnus. Their merger will produce a luminous red nova (a stellar explosion caused by the merging of two stars), is predicted to be visible to the naked eye, reaching magnitude 2.
