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 ...
Astrophotography is a popular hobby among photographers and amateur astronomers. Techniques ranges from basic film and digital cameras on tripods up to methods and equipment geared toward advanced imaging. Amateur astronomers and amateur telescope makersalso use homemade equipment and modified devices. Media.
Description Andromeda galaxy Ssc2005-20a1.jpg. English: NASA's Spitzer Space Telescope has captured stunning infrared views of the famous Andromeda galaxy to reveal insights that were only hinted at in visible light. This Spitzer's 24-micron mosaic is the sharpest image ever taken of the dust in another spiral galaxy.
The combination kept the camera aimed accurately over the long exposure time as the Earth rotated. Most consider Roberts' magnum opus to be a photograph showing the structure of M31, the Great Nebula in Andromeda (now known as the Andromeda Galaxy ).
Andromeda Galaxy (infrared) Original - Andromeda Galaxy in infrared, by the Spitzer space telescope. The Andromeda Galaxy is a spiral galaxy 2.5 million light-years away in the constellation Andromeda, making it the nearest spiral galaxy to the Milky Way. The exposure time of this image was 100 sec/pixel, and its scale is 2.8 x 0.8 degrees.
The Andromeda Galaxy and its satellite galaxy, Messier 110, to the bottom-right of the center. About half of the Andromeda's satellite galaxies are orbiting it along a highly flattened plane, with 14 out of 16 following the same sense of rotation. One theory proposes that these 16 once belonged to a subhalo surrounding M110, then the group was ...
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.
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.
