The Milky Way Galaxy  

In General > s.a. cosmic rays [propagation]; interstellar matter; local group [including satellites, DoS].
* Main properties: The disk is about 30 kpc across; It seems to have a bar structure, with only two main arms plus smaller ones.
* Motion: 2008, The generally accepted value of the rotational speed around us is 220 km/s, but 250 km/s may be a better value.
* Composition: The issue whether the disk or bulge is more metal-rich is much debated.
