NGC 7714 is a spiral galaxy in the constellation Pisces. It was discovered by John Herschel on 18 September 1830.
NGC 7714 and NGC 7715 are interacting galaxies. [3] The pair are also known as Arp 284. NGC 7714 appears to be a highly distorted spiral, possibly a barred spiral galaxy. NGC 7715 is of uncertain type, probably an edge-on spiral or an irregular galaxy. [2]
Three supernovae have been observed in NGC 7714: SN 1999dn (type Ib/c, mag. 16.3), [2] [4] SN 2007fo (type Ib/c, mag. 18.2), [5] and SN 2023pso (type Ib, mag. 17.1). [6]
Messier 66 or M66, also known as NGC 3627, is an intermediate spiral galaxy in the southern, equatorial half of Leo. It was discovered by French astronomer Charles Messier on 1 March 1780, who described it as "very long and very faint". This galaxy is a member of a small group of galaxies that includes M65 and NGC 3628, known as the Leo Triplet or the M66 Group. M65 and M66 are a common object for amateur astronomic observation, being separated by only 20′.
NGC 1532, also known as Haley's Coronet, is an edge-on barred spiral galaxy located approximately 50 million light-years from the Solar System in the constellation Eridanus. The galaxy was discovered by James Dunlop on 29 October 1826.
NGC 4088 is an intermediate spiral galaxy in the constellation Ursa Major. The galaxy forms a physical pair with NGC 4085, which is located 11′ away.
NGC 7479 is a barred spiral galaxy about 105 million light-years away in the constellation Pegasus. William Herschel discovered it in 1784. NGC 7479 is also recognized as a Seyfert galaxy and a LINER undergoing starburst activity not only on the nucleus and the outer arms, but also across the bar of the galaxy, where most of the stars were formed in the last 100 million years. Polarization studies of this galaxy indicate that it recently underwent a minor merger and that it is unique in the radio continuum, with arms opening in a direction opposite to the optical arms. This feature, along with the asymmetrical arms of the galaxy and the intense star formation activity are attributed to a merger with a smaller galaxy. This galaxy is similar in both size and morphology to the barred spiral NGC 1300.
NGC 772 is an unbarred spiral galaxy approximately 130 million light-years away in the constellation Aries.
NGC 4567 and NGC 4568 are a set of unbarred spiral galaxies about 60 million light-years away in the constellation Virgo. They were both discovered by William Herschel in 1784. They are part of the Virgo Cluster of galaxies.
Arp 299 is a pair of colliding galaxies approximately 134 million light-years away in the constellation Ursa Major. Both of the galaxies involved in the collision are barred irregular galaxies.
NGC 383 is a double radio galaxy with a quasar-like appearance located in the constellation Pisces. It is listed in Halton C. Arp's 1966 "The Arp Atlas of Peculiar Galaxies." Recent discoveries by the National Radio Astronomy Observatory in 2006 reveal that NGC 383 is being bisected by high energy relativistic jets traveling at relatively high fractions of the speed of light. The relativistic electrons in the jets are detected as synchrotron radiation in the x-ray and radio wavelengths. The focus of this intense energy is the galactic center of NGC 383. The relativistic electron jets detected as synchrotron radiation extend for several thousand parsecs and then appear to dissipate at the ends in the form of streamers or filaments.
NGC 1058 is a Seyfert Type 2 galaxy in the NGC 1023 Group, located in the Perseus constellation. It is approximately 27.4 million light years from Earth and has an apparent magnitude of 11.82. It is receding from Earth at 518 kilometers per second (322 mi/s), and at 629 kilometers per second (391 mi/s) relative to the Milky Way.
Arp 271 is a pair of similarly sized interacting spiral galaxies, NGC 5426 and NGC 5427, in the constellation of Virgo. It is not certain whether the galaxies are going to eventually collide or not. They will continue interacting for tens of millions of years, creating new stars as a result of the mutual gravitational attraction between the galaxies, a pull seen in the bridge of stars already connecting the two. Located about 130 million light-years away, the Arp 271 pair is about 130,000 light-years across. It was originally discovered in 1785 by William Herschel. It is speculated, that the Milky Way will undergo a similar collision in about five billion years with the neighbouring Andromeda Galaxy, which is currently located about 2.6 million light-years away.
NGC 4651 is a spiral galaxy located in the constellation of Coma Berenices that can be seen with amateur telescopes, at a distance not well determined that ranges from 35 million light years to 72 million light years.
NGC 6560 is a spiral galaxy located in the constellation Hercules. It was discovered by Lewis A. Swift on 22 October 1886.
NGC 6104 is a barred spiral galaxy located in the constellation Corona Borealis. It is designated as S(R)Pec in the galaxy morphological classification scheme, though it is clearly a barred spiral, and was discovered by William Herschel on 16 May 1787. The galaxy is approximately 388 million light-years away.
NGC 908 is an unbarred spiral galaxy in the constellation Cetus. It was discovered in 1786 by William Herschel. This galaxy is 56 million light years away from Earth. It is the main galaxy in the NGC 908 group, which also includes NGC 899, NGC 907, and IC 223.
NGC 1448 or NGC 1457 is an unbarred spiral galaxy seen nearly edge-on in the constellation Horologium. It is at a distance of 55 million light years from Earth. It was discovered by John Herschel in 1835.
NGC 1961 is a spiral galaxy in the constellation Camelopardalis. It was discovered by William Herschel on 3 December 1788. It is at a distance of about 200 million light years from Earth, which, given its apparent dimensions, means that NGC 1961 is more than 220,000 light years across.
NGC 3464 is a barred spiral galaxy in the constellation of Hydra, discovered 14 January 1886 by Ormond Stone.
NGC 7083 is an unbarred spiral galaxy located about 134 million light-years away in the constellation of Indus. It is also classified as a flocculent spiral galaxy. NGC 7083 was discovered by astronomer James Dunlop on August 28, 1826.
NGC 5468 is an intermediate spiral galaxy located in the constellation Virgo. It is located at a distance of about 140 million light-years from Earth, which, given its apparent dimensions, means that NGC 5468 is about 110,000 light-years across. It was discovered by William Herschel on March 5, 1785.
NGC 7448 is a spiral galaxy located in the constellation Pegasus. It is located at a distance of circa 80 million light years from Earth, which, given its apparent dimensions, means that NGC 7448 is about 60,000 light years across. It was discovered by William Herschel on October 16, 1784. It is included in the Atlas of Peculiar Galaxies in the category galaxies with detached segments.
