. This illustration shows the discovery that the outer Milky Way is a really a mixture of two distinct components rotating in opposite directions. The inner component of the Galaxy's halo spins clockwise with the galaxy's rotation at about 50,000 miles per hour. The outer component rotates counterclockwise to the galaxy at 100,000 miles per hour. SDSS-II, Masashi Chiba, Tohoku University, Japan

. Comment on J1130-1449 . There are two dominant components in our image. Comparison with the 15 GHz image of Kellermann et al. (1998) reveals that the western component is brighter at the higher frequency, indicating that the brighter (eastern) component in our image may have a steep spectrum. VLBApls home page .
