Superimposing picture showing sizes of the Moon and the Andromeda Galaxy as observed from Earth. Because the galaxy is not very bright from an amateur's point of view, its size is not evident. [138] [139] Under most viewing conditions, the Andromeda Galaxy is one of the most distant objects that can be seen with the naked eye, due
NASA recently released images of the Andromeda galaxy, an "enticing empire of stars" that can be seen with the naked eye if weather conditions are just right. About 100 years after astronomer ...
Zooming In on the Andromeda Galaxy, also known as Gigapixels of Andromeda, is a 2015 composite photograph of the Andromeda Galaxy produced by the Hubble Space Telescope. It is 1.5 billion pixels in size, and is the largest image ever taken by the telescope. [1] At the time of its release to the public, the image was one of the largest ever ...
With a variable brightness similar to Alpheratz, Mirach (Beta Andromedae) is a red giant, its color visible to the naked eye. The constellation's most obvious deep-sky object is the naked-eye Andromeda Galaxy (M31, also called the Great Galaxy of Andromeda), the closest spiral galaxy to the Milky Way and one of the brightest Messier objects.
Close to sunset and sunrise, bright stars like Sirius or even Canopus can be spotted with the naked eye as long as one knows the exact position in which to look. Historically, the zenith of naked-eye astronomy was the work of Tycho Brahe (1546–1601). He built an extensive observatory to make precise measurements of the heavens without any ...

Jupiter may be best known as the planetary titan of our solar system with a comparatively small red mark — that still dwarfs the entirety of Earth — and rows of striations going from pole to pole.
Slightly dimmer and more distant NGC 147 is a magnitude 9.3 elliptical galaxy, like NGC 185 it is an elliptical of type E0; it is 2.3 million light-years from Earth. Though they do not appear in Andromeda, both dwarf galaxies are gravitationally bound to the far larger Andromeda Galaxy. [42]
