It has a diameter of about 165,000 light-years and contains at least 200 billion stars. Its two brightest companion galaxies are M32 and M110. The light arriving at earth from the Andromeda Galaxy is shifted toward the blue end of the spectrum, whereas the light from all other cosmic sources exhibits red shift red shift or redshift, in astronomy, the systematic displacement of individual lines in the spectrum of a celestial object toward the red, or longer wavelength, end of the visible spectrum.

are rare today but were common in the early universe (170: 261). Laying out
the history, size, location, assistance in finding the Andromeda galaxy,
and so much more, The Andromeda Galaxy is very highly recommended for
all novice astronomers as a competent introduction to the Andromeda
galaxy, including the up-to-date research professional astronomy has
developed for with respect to our nearest neighboring galaxy. The spiral Andromeda galaxy, at a distance of nearly 3 million
light-years, resembled little more than a cottony puff. |
