Scientists have found a strange “break” in the spiral arms our Milky Way galaxy that could tell us more about  its galactic history.

The grouping of young stars and gassy regions is described by NASA’s Jet Propulsion Laboratory (JPL) as looking like “a splinter poking out from a plank of wood” from the plane of the spiral Milky Way’s arms.
