A head-on collision of the Andromeda Galaxy with the Milky Way is coming, according to astronomers! The next clear late November night you can see Andromeda, which is literally getting bigger second by second though you'd never know it by appearances. At around 9 p. The famed Andromeda Galaxy, otherwise known as M31, is at its highest and from even a semi-rural sky when there is no moonlight, you can see it with the naked eye. There are thousands of galaxies within reach of a small telescope on a dark night.

Andromeda Galaxy Visible to Eagle-Eye Skywatchers
A head-on collision of the Andromeda Galaxy with the Milky Way is coming, according to astronomers!
The Andromeda galaxy, our nearest massive galactic neighbor, is about six times larger and 1, times more massive than previously measured. Using the Hubble Space Telescope , astronomers have discovered that the immense halo of gas enveloping the Andromeda galaxy is about six times larger and 1, times more massive than previously thought. The dark, nearly invisible halo stretches about a million light-years from its host galaxy, halfway to our own Milky Way galaxy. This finding promises to tell astronomers more about the evolution and structure of majestic giant spirals, one of the most common types of galaxies in the universe.
Halo Around the Andromeda Galaxy is Larger Than Previously Thought
Observations of most galaxies do not show the individual stars — even the most powerful telescopes cannot normally resolve the cloudy white shapes into their hundreds of millions of constituent stars. In the case of the Andromeda Galaxy, however, astronomers have a few tricks up their sleeves. Secondly, M 31 is closer to our own galaxy than any other spiral galaxy so close that it can even be seen with the naked eye on a very dark night [1]. And thirdly, these observations avoid the crowded centre of the galaxy, where the stars are closest together and hardest to separate from each other. The resulting images offer a different perspective on a spiral galaxy.
Our galactic neighbour is visible all year from the UK, but clearest during the dark winter months. The distance between Cassiopeia and Andromeda is about three times the height of the W. With the naked eye, Andromeda will be extremely faint. Once you find the Great Square, let your eyes adjust and then count the number of stars you can see inside it. If you see no stars, it means the light pollution in your area is poor.
