Not all stars live their lives in solitary, like our sun, but most stars with the mass of the sun or larger are part of double or multiple-star systems. Of the approximately 5,000 stars that can be observed with the naked eye, about 2,000 appear to be binary or multiple stars. Only when two stars capture each other in their gravitational fields a binary star system is born and they will orbit around the common center of gravity which has arisen as a result. Now imagine living on a planet with two suns, how beautiful would it be to watch the sunsets and the sunrises. Every famous sci-fi author has written at least one story about living on such a planet and how to deal with the bizarre circumstances. Truth is, although a number of binary star systems have been found to harbor habitable planets, such systems are comparatively rare compared to single star systems. When planets have formed in the gravitational field of a binary star system, they can only support life if the orbital times of the two stars are optimal instead of e.g. cold and dark for days and then hot and blinding again. Orbital periods of two stars in a binary system can be less than an hour, or a few days, but also hundreds of thousands of years, but...

let's hope you can solve this stage way faster than that.
