When stars are born, more times than not, they arrive into the universe as twins. In the first step of stellar creation, a large cloud of gas and dust collapses due to gravity, often fragmenting into pieces. If each piece collapses again, multiple stars will be birthed from the same gas cloud. These infant suns are then surrounded by a halo of matter, the precursor to planets, known as a planet-forming disk. And, if these stars are close enough, the planet-forming disks around them can even swirl together, creating fantastic spiral tails.
