Our home spiral galaxy, the Milky Way Galaxy, just got a new look and it involves our neck of the woods. The "Local Arm", a spiral arm that includes the Sun and us, went from being a minor feature to one that is on the same scale as other major arms.
Old picture: Local Arm a small "spur" of Milky Way.
New picture: Local Arm probable major branch of Perseus Arm.
We can see portions of the Sagittarius Arm in summer and the Perseus Arm in winter.
