The coloured region is the previously known Galactic disk. The present work has extended its limits much farther away: there is a probability 99.7% or 95.4% respectively that there are disk stars in the regions outside the dashed/dotted circles. Yellow dot is the position of the Sun. Background Milky Way image from “A Roadmap to the Milky Way". Credit: Artistic representation by R. Hurt, SSC-Caltech, NASA/JPL-Caltech.
