Centaurus / s ɛ n ˈ t ɔːr ə s,-ˈ t ɑːr-/ is a bright constellation in the southern sky.One of the largest constellations, Centaurus was included among the 48 constellations listed by the 2nd-century astronomer Ptolemy, and it remains one of the 88 modern constellations.
Centaurus A (also known as NGC 5128 or Caldwell 77) is a galaxy in the constellation of Centaurus. ... The galaxy is also the fifth-brightest in the sky, [13] ...
The sky from α Centauri AB would appear much as it does from the Earth, except that Centaurus's brightest star, being α Centauri AB itself, would be absent from the constellation. The Sun would appear as a white star of apparent magnitude +0.5, [ 136 ] roughly the same as the average brightness of Betelgeuse from Earth.
Omega Centauri (ω Cen, NGC 5139, or Caldwell 80) is a globular cluster in the constellation of Centaurus that was first identified as a non-stellar object by Edmond Halley in 1677. Located at a distance of 17,090 light-years (5,240 parsecs), it is the largest known globular cluster in the Milky Way at a diameter of roughly 150 light-years. [10]
NGC 4945 (also known as Caldwell 83) is a barred spiral galaxy in the constellation Centaurus, visible near the star Xi Centauri. [3] The galaxy was discovered by James Dunlop in 1826 and is thought to be similar to the Milky Way Galaxy , although X-ray observations show that NGC 4945 has an unusual energetic Seyfert 2 nucleus that might house ...
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).
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.
Map showing the location of NGC 3766. NGC 3766 (also known as Caldwell 97) is an open star cluster in the southern constellation Centaurus.It is located in the vast star-forming region known as the Carina molecular cloud, and was discovered by Nicolas Louis de Lacaille during his astrometric survey in 1751–1752.
