Astronomers have recently discovered a new ultra-short period binary system, located in the constellation of Cygnus. This binary system consists of two stars that are orbiting each other in a unique way - with a period of just 12 minutes! This is the shortest orbital period ever observed in a binary system, and it provides astronomers with an exciting new opportunity to study the way stars interact. The stars in this system are both white dwarfs, and their extremely close proximity means that the system is a powerful source of gravitational waves. It is hoped that further observations of this system will provide more insights into the nature of binary systems and the evolution of stars.
