Talk:Galactic Directions

Spin direction[edit]

Have "Spinward" and "Anti-spinward" always been reversed on Inner Sphere maps?

I did some looking and found that the Milky Way rotates clockwise as seen from above (I multi-sourced that one to be certain). I then looked up a few stars (Terra and Aldebaran in the C.C., and Fomalhaut in the F.S.) and found there actual locations on a couple of 2D Star charts. Given their relationship in the Inner Sphere to the Real Milky Way, Spinward is towards the Rim Collection, and Anti-Spinward is towards the Outworlds Alliance.

Looks like it has been backwards for a long time, and it's something we just shrug about and live with as "game stuff"...

Yes, the Inner Sphere map is seen from "below" the galactic disk, and thus has the spin direction reversed versus a top-down view one might expect. It's always been like this. Frabby (talk) 14:49, 15 August 2014 (PDT)

Nope, it's just spinning backwards. If we were seeing it from below, Fomalhaut would be on the left of Terra, not the right. They used a lot existing stars when they made the IS map, they just got the spin direction flipped. How 'bout this... Spinward looks into the spin, as "Windward" looks into the wind. That makes "Spinward" "Up Spin", and "anti-Spinward" "Down-Spin" --- and I can totally live with that. :)

There is a discussion about this here:

Quote: "The standard orientation for Milky Way face-on maps in scientific publications (and this site) has 0° galactic longitude (the direction to the galactic nucleus) facing downwards. Hurt's illustration has it facing upwards. There is nothing scientifically invalid about this orientation (it is completely arbitrary) but it is still rather confusing. It's a bit like a map of the world with Antarctica at the top. This has some novelty value but is probably not the best orientation to use for general education."

So, this map can be replaced this map with one that has the appropriate galactic longitude orientation.
