Centaurus A (also known as NGC 5128 or Caldwell 77) is a galaxy in the constellation of Centaurus. It was discovered in 1826 by Scottish astronomer James Dunlop from his home in Parramatta , in New South Wales, Australia.
The location of NGC 4650A (circled in blue) NGC 4650A is a lenticular galaxy [5] of the rare polar-ring [6] type, located in the southern constellation of Centaurus.It has an apparent visual magnitude of 13.3 and spans an angular size of 1.6′ × 0.8′. [5]
NGC 4603 is a spiral galaxy located about 107 [2] million light years away in the constellation Centaurus. It is a member of the Centaurus Cluster of galaxies, belonging to the section designated "Cen30". The morphological classification is SA(s)c, [4] which indicates it is a pure spiral galaxy with relatively loosely wound arms. [5]
The spiral galaxy NGC 4622 lies approximately 111 million light-years away from Earth in the constellation Centaurus. NGC 4622 is an example of a galaxy with leading spiral arms . [ 2 ] Each spiral arm winds away from the center of the galaxy and ends at an outermost tip that "points" in a certain direction (away from the arm).
Hubble volume, a spherical region of the observable universe surrounding an observer beyond which objects recede from that observer at a rate greater than the speed of light due to the expansion of the universe, named after Edwin Hubble. KBC Void is an immense empty region of space, named after Ryan Keenan, Amy Barger, and Lennox Cowie.
Later observations (by Hubble himself, among others) showed Hubble's belief to be correct and the S0 class was included in the definitive exposition of the Hubble sequence by Allan Sandage. [12] Missing from the Hubble sequence are the early-type galaxies with intermediate-scale disks, in between the E0 and S0 types, Martha Liller denoted them ...
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. Nicolas-Louis de Lacaille discovered M83 on 17 February 1752 at the Cape of Good Hope. [8]
The atlas includes the nearby radio galaxies M87 (Arp 152) and Centaurus A (Arp 153). The peculiar associations present in the catalogue are now interpreted as galaxy mergers or non-interacting line-of-sight overlap, though Arp disputed that idea, claiming that apparent associations were examples of ejections.
