Canes Venatici /ˈkeɪniːz vɪˈnætɪsaɪ/ is one of the 88 official modern constellations. Cor Caroli is the constellation's brightest star, with an apparent magnitude of 2.9. One of the more significant galaxies in Canes Venatici is the Whirlpool Galaxy (M 51, NGC 5194) and NGC 5195, a small barred spiral galaxy that is seen face-on. . In this proposed scenario, NGC 5195 came from behind M51 through the disk towards the observer and made another disk crossing as recently as 50 to 100 million years ago until it is where we observe it to be now, slightly behind M51. Its distance is estimated to be 23 million light-years away from Earth. In 1533, the German astronomer Peter Apian depicted Boötes as having two dogs with him. The Sunflower Galaxy, also known as Messier 63 (M63), is a bright spiral galaxy located in the constellation Canes Venatici. This website uses cookies to personalise content and ads, and to analyse user traffic. Messier 106 (M106) is a spiral galaxy located in the constellation Canes Venatici, the Hunting Dogs.. M106 lies at a distance of 23.7 million light years from Earth and has an apparent magnitude of 9.1. This group lies directly behind the Canes I group, and there are many groups of galaxies in this area of the sky which ultimately connect to the massive Virgo cluster fifty million light years away. Canes Venatici Constellation [Stellarium] The Sun joins Copula on September 17 Fixed star Copula, or The Whirlpool Galaxy (M51a, or NGC 5194) is a spiral galaxy in the Hunting Dogs, Canes Venatici … The Giant Void, an extremely large void (part of the universe containing very few galaxies), is within the vicinity of this constellation. [4], These spurious dogs floated about the astronomical literature until Hevelius decided to make them a separate constellation in 1687. r − The transient was later identified as a luminous red nova. The Whirlpool Galaxy is a spiral galaxy tilted face-on to observers on Earth, and was the first galaxy whose spiral nature was discerned. Its name is Latin for 'hunting dogs', and the constellation is often depicted in illustrations as representing the dogs of Boötes the Herdsman, a neighboring constellation. In the equatorial coordinate system, the right ascension coordinates of these borders lie between 12h 06.2m and 14h 07.3m , while the declination coordinates are between +27.84° and +52.36°. Constellation in the northern celestial hemisphere, The 41 additional constellations added in the 16th, 17th and 18th centuries, Hevelius' name for the northern dog, Asterion, is from the Greek, Hevelius' name for the southern dog, Chara, is from the Greek, harvnb error: no target: CITEREFKunitzsch1974 (, harvnb error: no target: CITEREFRidpath2001 (, Learn how and when to remove this template message, Centre de données astronomiques de Strasbourg, Photos of Canes Venatici and the star clusters and galaxies found within it on AllTheSky.com, Photographic catalogue of deep sky objects in Canes Venatici (PDF), Constellations introduced by Johannes Hevelius, https://en.wikipedia.org/w/index.php?title=Canes_Venatici&oldid=984479265, Constellations listed by Johannes Hevelius, Articles with incomplete citations from September 2020, Articles with failed verification from October 2020, Articles needing additional references from October 2020, All articles needing additional references, Creative Commons Attribution-ShareAlike License, This page was last edited on 20 October 2020, at 08:41. The story behind the name: Hevelius was an observational astronomer who cataloged stars, and created some new constellations in parts of the sky where none had been marked out by earlier civilizations. Rosse revealed the spiral structure of Whirlpool galaxy (M51) at the 1845 meeting of the British Association for the Advancement of Science. – Messier 3 (NGC 5272) may not be a galaxy, but it is one of the oldest, brightest, and biggest globular star clusters ever discovered, containing about half a million stars. [12] Its companion galaxy, NGC 5195, was discovered in 1781 by Pierre Méchain, although it was not known whether it was interacting or merely another galaxy passing at a distance. Canes Venatici is also home of the Sunflower Galaxy (aka. Dreyer calls it very bright (mag. It has the designation NGC 4258 in the New General Catalogue. The planet was detected by eclipses of the X-ray source (XRS), which consists of a stellar remnant (either a neutron star or a black hole) and a massive star, likely a B-type supergiant. NGC 4631 photographed by the Hubble Space Telescope. In January 2005 the Hubble Heritage Project constructed a 11477 × 7965-pixel composite image (shown in the infobox above) of M51 using Hubble's ACS instrument. It is passing behind M 51 and may be the cause of the larger galaxy's prodigious star formation.[18]. Canes Venatici / ˈ k eɪ n iː z v ɪ ˈ n æ t ɪ s aɪ / is one of the 88 official modern constellations.It is a small northern constellation that was created by Johannes Hevelius in the 17th century. [7][6][8] It lies in the constellation Canes Venatici, and was the first galaxy to be classified as a spiral galaxy. It is estimated that the current high rate of star formation can last no more than another 100 million years or so. Whirlpool Galaxy lies 23 million light-years from Earth and has an estimated diameter of 76,000 light-years. Messier 51, the Whirlpool Galaxy, photographed by the Hubble Space Telescope. [9] Its distance is estimated to be 23 million light-years away from Earth. [30][31][32][33] This small group may actually be a subclump at the southeast end of a large, elongated group that includes the M101 Group and the NGC 5866 Group, although most group identification methods and catalogs identify the three groups as separate entities. along with the particularly nice seeing offered by the Canada-France-Hawaii-Telescope (C.F.H.T.) The Virgo galaxy cluster is the only rich galaxy cluster in the Local Supercluster, and none of the listed galaxy clouds … Any cookies that may not be particularly necessary for the website to function and is used specifically to collect user personal data via analytics, ads, other embedded contents are termed as non-necessary cookies. Widely considered to be one of the most beautiful galaxies visible, M 51 has many star-forming regions and nebulae in its arms, coloring them pink and blue in contrast to the older yellow core. Messier 106 (M106) is a spiral galaxy located in the constellation Canes Venatici, the Hunting Dogs. NGC 4248 is located about 24 million light-years away.

Coordinates: 13h 29m 52.7s, +47° 11′ 43″, Whirlpool Galaxy – Observed in Various Light, a) 0.4; 0.7 μm – b) vis-blue/green; ir-red – c) 3.6; 4.5; 8 μm – d) 24 μm. 25, pp. The galaxy lies at a distance of 37 million light years from Earth and has an apparent magnitude of 9.3. Together, the two galaxies are one of the most widely studied interacting galaxy pairs. M51 is visible through binoculars under dark sky conditions, and it can be resolved in detail with modern amateur telescopes. La Superba (Y CVn) is one of the reddest naked-eye stars and one of the brightest carbon stars. The galaxy lies at a distance of 37 million light years from Earth and has an apparent magnitude of 9.3. Both galaxies are located approximately 25 million light-years away in the constellation Canes Venatici. On 31 May 2011 a type II supernova was detected in the Whirlpool Galaxy, peaking at magnitude 12.1. [12] It is a face-on spiral galaxy 37 million light-years from Earth. The image highlights the galaxy's spiral arms, and shows detail into some of the structures inside the arms.[15]. In 1845, William Parsons, 3rd Earl of Rosse, employing a 72-inch (1.8 m) reflecting telescope at Birr Castle, Ireland, found that the Whirlpool possessed a spiral structure, the first "nebula" to be known to have one. These cookies do not store any personal information. No object could be seen at the position of the transient in archival Hubble images, indicating that the progenitor star was heavily obstructed by interstellar dust. As is usual for galaxies, the true extent of its structure can only be gathered from inspecting photographs; long exposures reveal a large nebula extending beyond the visible circular appearance. [8], Although the International Astronomical Union dropped several constellations in 1930 that were medieval and Renaissance innovations, Canes Venatici survived to become one of the 88 IAU designated constellations.[9]. M 51 has a smaller companion, NGC 5195, that has very few star-forming regions and thus appears yellow. Here are some of the highlights of the night sky in May: 9 PM eastern sky – Saturn and Mars staying in the sky from nightfall until the early morning hours, with Saturn making its closest approach to Earth on May 10 9 PM western sky – Mercury above the horizon after sunset, Jupiter visible … [Read more…], The Whirlpool Galaxy, also known as Messier 51 (M51) and NGC 5194, is a grand-design spiral galaxy in Canes Venatici.
