A bright new star will burst into the sky in five years, astronomers predict

The location of what may become one of the brightest stars in the sky.
This quest to comprehend red novas began when Molnar and then-Calvin College student Daniel Van Noord attended a presentation by astronomer Karen Kinemuchi of Apache Point Observatory in New Mexico, that asked if KIC 9832227 was a pulsing or binary star. Van Noord, who has since graduated, began dedicated observations at the Calvin observatory, where he found the orbital period shrinking.
The two spinning stars share a communal atmosphere like two peanuts sharing a common shell, Molnar said.
Beyond what humans can see with the unaided eye, KIC 9832227 is currently a 12th magnitude object, which means it's pretty dim. When it explodes sometime around 2022, we expect it will reach second magnitude at the brightest, Molnar said, where it will be among the brighter stars in the sky.
