Calvin College professor of astronomy Larry Molnar made a bold announcement in 2017—he and his team had identified a binary star in the constellation Cygnus, the Swan, that was a strong candidate to merge and explode in the near future. Known by its Kepler mission number, KIC 9832227, the pair of stars is about 1800 light years from Earth and has an orbit so close that it takes just 11 hours to go around once. That first-of-its-kind prediction caught the attention of an international audience, creating excitement within the scientific community and among the general public.
