You Are Here


NASA has released a new map of our home galaxy, the Milky Way, and it turns out it only has two spiral arms instead of four, which is what we used to think the galaxy looked like. Old maps had Sol, our sun, in the Orion Spiral Arm, but now the sun is seated in the Orion Spur of the Perseus Spiral Arm, not that it makes much difference on planning your route to the grocery store, but it's always a good idea to know where you stand.
