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 ...
The prospect of using WISE was proposed by NASA officials. [30] NASA officials told Committee staff that NASA plans to use WISE to detect [near-Earth objects in addition to performing its science goals. It was projected that WISE could detect 400 NEOs (or roughly 2% of the estimated NEO population of interest) within its one-year mission.
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 ...
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]
NGC 206 is the richest and most conspicuous star cloud in the Andromeda Galaxy, and is one of the largest and brightest star-forming regions in the Local Group. [2] It contains more than 300 stars brighter than M b =−3.6. [3] It was originally identified by Edwin Hubble as a star cluster but today, due to its size, it is classified as an OB ...
A NASA conception of the collision using computer-generated imagery. While the Andromeda Galaxy contains about 1 trillion (10 12) stars and the Milky Way contains about 300 billion (3 × 10 11), the chance of even two stars colliding is negligible because
NGC 13 is a spiral galaxy [1] in the constellation Andromeda. It is estimated to be about 220 million light-years (66 Megaparsecs) away from the Sun. [ 1 ] It was discovered on November 26, 1790, by William Herschel .
NGC 49 is a lenticular galaxy in the Andromeda constellation. The galaxy was discovered by the American astronomer Lewis A. Swift on September 7, 1885. [3] References
