Astronomy Picture of the Day (APOD) is a website provided by NASA and Michigan Technological University (MTU). It reads: "Each day a different image or photograph of our universe is featured, along with a brief explanation written by a professional astronomer." [1] The photograph does not necessarily correspond to a celestial event on the exact ...
Companion. NGC 5195 (also known as Messier 51b or M51b) is a dwarf galaxy that is interacting with the Whirlpool Galaxy (also known as M51a or NGC 5194). Both galaxies are located approximately 25 million light-years away in the constellation Canes Venatici. Together, the two galaxies are one of the most widely studied interacting galaxy pairs.
Messier 94. Messier 94 (also known as NGC 4736, Cat's Eye Galaxy, Crocodile Eye Galaxy, or Croc's Eye Galaxy[7][8]) is a spiral galaxy in the mid- northern constellation Canes Venatici. It was discovered by Pierre Méchain in 1781, [9] and catalogued by Charles Messier two days later. Although some references describe M94 as a barred spiral ...
The location of Arp 273 (circled in blue) Arp 273 is a pair of interacting galaxies, 300 million light years away in the constellation Andromeda.It was first described in the Atlas of Peculiar Galaxies, compiled by Halton Arp in 1966. [5]
NGC 2359 (also known as Thor's Helmet) is an emission nebula [3] in the constellation Canis Major. The nebula is approximately 3,670 parsecs (11.96 thousand light years) away and 30 light-years in size. The central star is the Wolf-Rayet star WR7, an extremely hot star thought to be in a brief pre- supernova stage of evolution.
Hourglass nebula [4] See also: Lists of nebulae. The Lagoon Nebula (catalogued as Messier 8 or M8, NGC 6523, Sharpless 25, RCW 146, and Gum 72) is a giant interstellar cloud in the constellation Sagittarius. It is classified as an emission nebula and has an H II region. The Lagoon Nebula was discovered by Giovanni Hodierna before 1654 [5] and ...
NGC 7331 Group is a visual grouping of galaxies in the constellation Pegasus. Spiral galaxy NGC 7331 is a foreground galaxy in the same field as the collection, which is also called the Deer Lick Group. [1] It contains four other members, affectionately referred to as the "fleas": the lenticular or unbarred spirals NGC 7335 and NGC 7336, the ...
NGC 7635, also known as the Bubble Nebula, Sharpless 162, or Caldwell 11, is an H II region [1] emission nebula in the constellation Cassiopeia. It lies close to the open cluster Messier 52 . The "bubble" is created by the stellar wind from a massive hot, 8.7 [ 1 ] magnitude young central star , SAO 20575 ( BD+60°2522 ). [ 7 ]
