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 ...
The most famous deep-sky object in Andromeda is the spiral galaxy cataloged as Messier 31 (M31) or NGC 224 but known colloquially as the Andromeda Galaxy for the constellation. [53] M31 is one of the most distant objects visible to the naked eye, 2.2 million light-years from Earth (estimates range up to 2.5 million light-years). [ 54 ]
Cassiopeia (constellation) Visible at latitudes between + 90 ° and − 20 °.Best visible at 21:00 (9 p.m.) during the month of November. Cassiopeia (listen ⓘ) is a constellation and asterism in the northern sky named after the vain queen Cassiopeia, mother of Andromeda, in Greek mythology, who boasted about her unrivaled beauty.
This October 2023 photo of the Andromeda Galaxy was taken from the author's backyard using an 8-inch telescope. The spiral galaxy is considered the most distant object that can be seen with the ...
The Andromeda Galaxy is the farthest deep-sky object the human eye can spot at about 2.5 million light-years away. It can also be tricky to find, but here's how you can spot our galactic neighbor.
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. [1][2][3][4][5] The stars involved are sufficiently far apart that it is improbable that any of them ...
The Andromeda Galaxy (M31) has satellite galaxies just like the Milky Way. Orbiting M31 are at least 13 dwarf galaxies: the brightest and largest is M110, which can be seen with a basic telescope. The second-brightest and closest one to M31 is M32. The other galaxies are fainter, and were mostly discovered starting from the 1970s.
