Waltzing dwarfs

This video shows the two brown dwarfs from the Luhman 16AB system as they move both across the sky and around each other. The movement seen in this video occurred over the course of three years and was observed by the NASA/ESA Hubble Space Telescope. The researchers studied the system in the hope of finding a planetary companion. However, the movement of the two brown dwarfs indicated that they are indeed unperturbed by a massive planetary companion.
