n MNASSA : Monthly Notes of the Astronomical Society of South Africa - News note : zone of avoidance radio survey




One of the bugbears faced by astronomers interested in studying the distribution of galaxies over the whole sky is the Milky Way - our own galaxy! Unfortunately it hides a large part of the distant universe behind its gas, dust and stars. The part of the sky obscured in this way is known as the Zone of Avoidance. For many years there have been indications of substantial numbers of galaxies hidden from us in this region, including those contributing to a hypothesized "Great Attractor" that affects the gravitational field felt by nearby galaxies.
