This illustrates the fact that there are far more faint stars than bright stars: in the entire sky, there are about 500 stars brighter than apparent magnitude 4 but 15.5 million stars brighter than apparent magnitude 14. [108] The apex of the Sun's way, or the solar apex, is the direction that the Sun travels through space in the Milky Way.
The image shows the galaxy cluster SMACS 0723 as it appeared 4.6 billion years ago, [4] covering an area of sky with an angular size approximately equal to a grain of sand held at arm's length. [3] Many of the objects in the image have undergone notable redshift due to the expansion of space over the extreme distance traveled by the light ...
In June 2023 detection of organic molecules 12 billion light-years away in a galaxy called SPT0418-47 using the Webb telescope was announced. [278] On 12 July 2023, NASA celebrated the first year of operations with the release of Webb's image of a small star-forming region in the Rho Ophiuchi cloud complex, 390 light years away. [279]
Messier 81 (also known as NGC 3031 or Bode's Galaxy) is a grand design spiral galaxy about 12 million light-years away in the constellation Ursa Major. It has a D 25 isophotal diameter of 29.44 kiloparsecs (96,000 light-years ).
Southern Pinwheel Galaxy, ESO 444- G 081, IRAS 13341-2936, NGC 5236, UGCA 366, MCG-05-32-050, PGC 48082 [6] Messier 83 or M83 , also known as the Southern Pinwheel Galaxy and NGC 5236 , is a barred spiral galaxy [ 7 ] approximately 15 million light-years away in the constellation borders of Hydra and Centaurus .
The galaxy's name stems from the area of Earth's sky in which it appears, the constellation of Andromeda, which itself is named after the princess who was the wife of Perseus in Greek mythology. [8] The virial mass of the Andromeda Galaxy is of the same order of magnitude as that of the Milky Way, at 1 trillion solar masses (2.0 × 10 42 ...
The following is a list of stars with resolved images, that is, stars whose images have been resolved beyond a point source. Aside from the Sun , observed from Earth , stars are exceedingly small in apparent size, requiring the use of special high-resolution equipment and techniques to image.
Dark sky image with some objects around Pinwheel Galaxy (M 101). The quarter in the lower right shows the tail of Ursa Major with the stars Mizar, Alcor and Alkaid.. The Pinwheel Galaxy (also known as Messier 101, M101 or NGC 5457) is a face-on, unbarred, and counterclockwise spiral galaxy located 21 million light-years (6.4 megaparsecs) [5] from Earth in the constellation Ursa Major.
