galactic halo
Definition(s)
- A galactic halo is a large, relatively dust-free, spherical region surrounding a spiral galaxy, such as our own. The inner, visible part of the halo, which has roughly the same diameter as the galactic disk, is occupied by Population II objects, including globular clusters and old, individual stars. Beyond this is a much larger region, called the dark halo or extended halo. (Encyclopedia of Science, by David Darling, https://www.daviddarling.info/encyclopedia/G/galhalo.html)
