has definition the galactic halo, however, describes the spherical collection of stars forming a surrounding "shell" for our otherwise compact, discoid Galaxy. has source: Abbot, D. 1984 Astronomers, Peter Bedrick Books, New York, 2001-09-27 09:32:18.0
has definition The somewhat round population of old, metal-poor stars in the Milky Way. Also, the huge entity that surrounds the disk and contains most of the Galaxy's dark matter. To distinguish between the two, astronomers call the former the stellar halo and the latter the dark halo. Most of the stellar halo lies closer to the Galactic center than the Sun, while most of the dark halo lies farther from the Galactic center than the Sun. has source: Croswell, K. 1995 The Alchemy of the Heavens, Anchor Books, 2001-09-27 09:32:18.0
has definition A spherical aggregation of stars, globular star clusters, and thin gas clouds, centered on the nucleus of the galaxy and extending beyond the known extremities of the galactic disk. has source: Ferris, T. 1988 Coming of Age in the Milky Way, Morrow, 2001-09-27 09:32:18.0
