. 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 .

Abstract -- The strengths of magnetic fields in interstellar gas clouds are obtained through observations of the circular polarization of spectral line radiation. ... To infer information about these irregularities from the observational data, we develop statistical relationships between the rms values of the irregular component of the magnetic field and spatial variations in the circular polarization of the spectral line radiation. ...
