Parallel? Did you mean perpendicular?

Cool Pic!
from:
IRAS View Of The Milky Way Galaxy
"The hazy, horizontal S-shaped feature that crosses the image is faint heat emitted by dust in the plane of the solar system."
Yes, that blue line is at ~60 degrees! Not quite the 90 degrees I thought it was, but still far from parallel.

PHY 445/515: Coordinate Systems
"The ecliptic coordinate system is based on the apparent Solar orbit, and is the natural system for Solar System studies.... The inclination of the ecliptic with respect to the celestial equator is 23 degrees."
Shouldn't that 23 degrees be added onto the 62 degrees (Earth's angle) to get the angle of the solar system to the galactic plane?
But it looks like 60ish degrees.
Maybe that's a mistake, and they should be saying "The galactic equator is inclined to the
celestial ecliptic equator by 62.6 degrees."
...or does it just "look" that (62 degrees) way because it's photographed from earth?
...and the galactic equator would be inclined ~86 (62.6+23.3) degrees to the ecliptic equator?

Any info. on direction of travel (Southern Hemisphere forward?)?

Great links: Thanks,
