New Milky Way map reveals a wave of stars in our galaxy's outer reaches
CNN
A new map reveals the outskirts of the Milky Way galaxy, including a wave of stars disturbed by a small galaxy on a collision course with our own.
Data collected from the European Space Agency's Gaia mission and NASA's Near Earth Object Wide Field Infrared Survey Explorer has been used by astronomers to map the galactic halo and this group of stars. Their findings appear in a study published Wednesday in the journal Nature. Our Milky Way is a galaxy with multiple spiral arms emanating from a central disk. The empty-looking halo lies outside of these swirling arms. But there may be more to the halo than meets the eye.More Related News
