Telescopium−Grus Cloud
The Telescopium−Grus Cloud is a galaxy filament in the constellations of Pavo, Indus, and Telescopium. It was first defined by astronomer R. Brent Tully, Brent Tully in his book ''The Nearby Galaxies Atlas'' and its companion book ''The Nearby Galaxies Catalog.'' In 2014, it was announced that the Southern Supercluster Strand is a lobe in a greater supercluster, Laniakea Supercluster, Laniakea, that is centered on the Great Attractor. This would mean that the Southern Supercluster Strand's components, the Telescopium−Grus Cloud and the Southern Supercluster would be part of this new supercluster. The Virgo Supercluster would also be part of this greater supercluster, thus becoming the local supercluster. Physical characteristics The Telescopium−Grus Cloud is a collection of at least 24 Galaxy group, galaxy groups. It is low density galaxy filament, with no central concentration of galaxies. The filament along with the Pavo–Indus Supercluster, Pavo-Indus Supercluster for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern Supercluster Strand
The Southern Supercluster Strand is a galaxy filament that incompasses the Southern Supercluster and the Telescopium−Grus Cloud. In 2014, it was announced that the Southern Supercluster Strand is a lobe in a greater supercluster, Laniakea Supercluster, Laniakea, that is centered on the Great Attractor. This would mean that the Southern Supercluster Strand's components, the Telescopium−Grus Cloud and the Southern Supercluster would be part of this new supercluster. The Virgo Supercluster would also be part of this greater supercluster, thus becoming the local supercluster. Physical characteristics The Southern Supercluster Strand is a galaxy filament that emerges from the Centaurus Cluster. The filament then branches off into two forks, SSCa, and SSCb, also known as the Southern Supercluster and the Telescopium−Grus Cloud respectively. The Southern Supercluster is a long major chain of galaxies, consisting of the major Dorado Group, Dorado, Fornax Cluster, Fornax, and Eri ...

Perseus–Pisces Supercluster
The Perseus–Pisces Supercluster (SCl 40) is one of the largest known structures in the universe. Even at a distance of 250 million light-years, this chain of galaxy clusters extends more than 40° across the northern winter sky. The Perseus– Pisces Supercluster is one of two dominant concentrations of galaxies (the other being the Local supercluster) in the nearby universe (within 300 million light years). This supercluster also borders a prominent void, the Taurus Void, and is part of the Perseus–Pegasus Filament which stretches for roughly a billion light year A light-year, alternatively spelled light year (ly or lyr), is a unit of length used to express astronomical distance, astronomical distances and is equal to exactly , which is approximately 9.46 trillion km or 5.88 trillion mi.

Richard R
Richard is a male given name. It originates, via Old French, from Old Frankish and is a compound of the words descending from Proto-Germanic language">Proto-Germanic ''*rīk-'' 'ruler, leader, king' and ''*hardu-'' 'strong, brave, hardy', and it therefore means 'strong in rule'. Nicknames include " Richie", " Dick", " Dickon", " Dickie", " Rich", " Rick", "Rico (name), Rico", " Ricky", and more. Richard is a common English (the name was introduced into England by the Normans), German and French male name. It's also used in many more languages, particularly Germanic, such as Norwegian, Danish, Swedish, Icelandic, and Dutch, as well as other languages including Irish, Scottish, Welsh and Finnish. Richard is cognate with variants of the name in other European languages, such as the Swedish "Rickard", the Portuguese and Spanish "Ricardo" and the Italian "Riccardo" (see comprehensive variant list below).

Brent Tully
Richard Brent Tully (born March 9, 1943) is a Canadian-born American astronomer at the Institute for Astronomy in Honolulu, Hawaii. Born in Toronto, Ontario, and raised in Vancouver, British Columbia, Tully's specialty is the astrophysics of galaxies. With J. Richard Fisher, he proposed the Tully–Fisher relation, which shows that the luminosity of a galaxy and the orbital velocities of its stars are correlated. This relation can be used to determine the distances of galaxies and, by inference, the size and age of the universe. His books ''The Nearby Galaxies Atlas & Catalog'' published in 1988 give the 3D locations for 2,400 galaxies within 130 million light years of Earth. A particularly remarkable discovery was that our Milky Way galaxy lies adjacent a vast underdense region that Tully called the Local Void. A more extended compilation of 30,000 galaxies within a cube of diameter 700 million light years centered on Earth can be visually navigated with the planetarium ...

Gérard De Vaucouleurs
Gérard Henri de Vaucouleurs (25 April 1918 – 7 October 1995) was a French astronomer best known for his studies of galaxies. Life and career Gérard de Vaucouleurs was born on April 25, 1918 in Paris, he took the maiden name of his mother as his last name. He had an early interest in amateur astronomy and received his undergraduate degree in 1939 at the Sorbonne in that city. After military service in World War II, he resumed his pursuit of astronomy. He was married to fellow astronomer Antoinette de Vaucouleurs on October 31, 1944, and the couple would frequently collaborate on astronomical research. He was fluent in English and spent 1949-51 in England and 1951–57 in Australia at Mount Stromlo Observatory. He was at Lowell Observatory in Arizona from 1957-1958 and at Harvard from 1958-60.

Telescopium Cluster
Telescopium is a minor constellation in the southern celestial hemisphere, one of twelve named in the 18th century by French astronomer Nicolas-Louis de Lacaille and one of several depicting scientific instruments. Its name is a Latinized form of the Greek word for telescope. Telescopium was later much reduced in size by Francis Baily and Benjamin Gould. The brightest star in the constellation is Alpha Telescopii, a blue-white subgiant with an apparent magnitude of 3.5, followed by the orange giant star Zeta Telescopii at magnitude 4.1. Eta and PZ Telescopii are two young star systems with debris disks and brown dwarf companions. Telescopium hosts two unusual stars with very little hydrogen that are likely to be the result of two merged white dwarfs: PV Telescopii, also known as HD 168476, is a hot blue extreme helium star, while RS Telescopii is an R Coronae Borealis variable. RR Telescopii is a cataclysmic variable that brightened as a nova to magnitude 6 in 1948. It had ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NGC 7213
NGC 7213 is a lenticular galaxy located in the constellation Grus. It is located at a distance of circa 70 million light-years from Earth, which, given its apparent dimensions, means that NGC 7213 is about 75,000 light-years across. It was discovered by John Herschel on September 30, 1834. It is an active galaxy with characteristics between a type I Seyfert galaxy and LINER. Characteristics The nucleus of NGC 7213 features activity and belongs to the low-luminosity active galactic nuclei (LLAGN). The optical spectrum features broad H-alpha lines and has similar characteristics to a type I Seyfert galaxy, however it is considerably less luminous than other similar galaxies. It also features e Vλ3426, He II λ4686, IIλ3726, 3729, 7319, 7330, IIIλ4363, 4959, and 5007 emission lines. However the intensity ratios of many of these lines is similar to a LINER. Observed in radio waves, NGC 7213 looks like a point-like source that could feature two jets that bend between one 1 ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NGC 7196
NGC 7196 is an elliptical galaxy registered in the New General Catalogue. It is located in the direction of the Indus constellation, at a distance of circa 150 million light years. It was discovered by the English astronomer John Herschel in 1834 using a 47.5 cm (18.7 inch) reflector. NGC 7196 appears slightly distorted, with asymmetric outer isophotes. Asymmetry is also observed near the centre. The inner luminosity pattern resembles that of lenticular galaxies with circumscribing dust lanes, except that the feature is extremely close to the center.Sandage, A., Bedke, J. (1994), ''The Carnegie Atlas of Galaxies. Volume I'', Carnegie Institution of Washington A shell has been observed around the galaxy. Shells are generally considered to have formed after the accretion of a smaller galaxy by a massive one. It has weak radio wave emission. NGC 7196 is the foremost member of a galaxy group known as the NGC 7196 group, which also includes NGC 7200 and some dwarf elliptical a ...

NGC 7079
NGC 7079 is a barred lenticular galaxy located about 110.58 million light-years away in the constellation of Grus. NGC 7079 is also classified as a LINER galaxy. It is tilted about 51° to the Earth's line of sight. NGC 7079 was discovered by astronomer John Herschel on September 6, 1834. Physical characteristics NGC 7079 has a faint cigar-shaped bar with ansae at the ends, and there is another very faint spiral structure surrounding it. The rim of the disk also has a somewhat faint ring-like structure. Emission of doubly ionized oxygen gas In NGC 7079, it has been indicated that there is a faint emission of doubly ionized oxygen. The ionized gas is rotating in the opposite direction of the stars in the galaxy. The counter-rotation has been attributed to the accretion of gas from outside of the galaxy. Group membership NGC 7079 is a member of the NGC 7079 Group. The group, along with other nearby groups are part of the Pavo-Indus and Grus clouds of galaxies which form a conn ...
