The Andromeda–Milky Way collision is a galactic collision predicted to occur in about 4.5 billion years between the two largest galaxies in the Local Group—the Milky Way (which contains the Solar System and Earth) and the Andromeda Galaxy.
The Andromeda Galaxy is a barred spiral galaxy and is the nearest major galaxy to the Milky Way. It was originally named the Andromeda Nebula and is cataloged as Messier 31 , M31 , and NGC 224 . Andromeda has a D 25 isophotal diameter of about 46.56 kiloparsecs (152,000 light-years ) [ 8 ] and is approximately 765 kpc (2.5 million light-years ...
English: This animation depicts the collision between our Milky Way galaxy and the Andromeda galaxy. Hubble Space Telescope observations indicate that the two galaxies, pulled together by their mutual gravity, will crash together about 4 billion years from now. Around 6 billion years from now, the two galaxies will merge to form a single galaxy.
While it takes light approximately 2.54 million years to traverse the gulf of space between Earth and, for instance, the Andromeda Galaxy, it would take a much shorter amount of time from the point of view of a traveler at close to the speed of light due to the effects of time dilation; the time experienced by the traveler depending both on velocity (anything less than the speed of light) and ...
NGC 999 is an intermediate spiral galaxy located in the constellation Andromeda about 195 million light-years from the Milky Way. [3] It was discovered by French astronomer Edouard Stephan on 8 December 1871.
NGC 828 is a spiral galaxy in the constellation of Andromeda. Its velocity with respect to the cosmic microwave background is 5200 ± 17 km/s, which corresponds to a Hubble distance of 250.2 ± 17.5 Mly (76.70 ± 5.37 Mpc). [1] Additionally, three non-redshift measurements give a distance of 223.52 ± 7.06 Mly (68.533 ± 2.165 Mpc). [2]
Known as the M31 Galaxy, Andromeda is the closest spiral galaxy to our own Milky Way, located about 2.5 million light-years away. It contains over a trillion stars, and is one of the few galaxies ...
NGC 80 is a lenticular galaxy located in the constellation Andromeda. It is currently interacting with two other barred spiral galaxies NGC 47 and NGC 68 , and was discovered on August 17, 1828 by John Herschel .
