Virgo is one of the constellations of the zodiac. Its proper noun is Latin for maiden, and its old astronomical symbol is 
(♍︎). Lying between Leo to the westward and Libra to the east, information technology is the second-largest constellation in the sky (after Hydra) and the largest constellation in the zodiac. The ecliptic intersects the angelic equator within this constellation and Pisces. Underlying these technical ii definitions, the sunday passes directly overhead of the equator, within this constellation, at the September equinox. Virgo can be easily found through its brightest star, Spica.[1]
Location [edit]
Virgo is prominent in the spring heaven in the northern hemisphere, visible all night in March and April. As the largest zodiac constellation, the Sun takes 44 days to laissez passer through it, longer than any other. From 1990 and until 2062, this will take place from September 16 to October thirty. It is located in the third quadrant of the southern hemisphere (SQ3) and can be seen at latitudes betwixt +lxxx° and -80°.
The bright star Spica makes it piece of cake to locate Virgo, as it tin can be found by following the curve of the Big Dipper/Plough to Arcturus in Boötes and continuing from there in the same curve ("follow the arc to Arcturus and speed on to Spica").[2]
Due to the effects of precession, the Outset Point of Libra, (also known as the fall equinox betoken) lies within the boundaries of Virgo very shut to β Virginis. This is ane of the two points in the sky where the celestial equator crosses the ecliptic (the other beingness the Get-go Point of Aries, at present in the constellation of Pisces). From the 18th century to the 4th century BC, the Sun was in Libra on the autumnal equinox, shifting into Virgo thereafter. This point will laissez passer into the neighboring constellation of Leo around the twelvemonth 2440.
Features [edit]
Stars [edit]
Too Spica, other bright stars in Virgo include β Virginis (Zavijava), γ Virginis (Porrima), δ Virginis (Auva) and ε Virginis (Vindemiatrix). Other fainter stars that were also given names are ζ Virginis (Heze), η Virginis (Zaniah), ι Virginis (Syrma), κ Virginis (Kang), λ Virginis (Khambalia) and φ Virginis (Elgafar).
The star lxx Virginis has one of the first known extrasolar planetary systems with i confirmed planet 7.5 times the mass of Jupiter.
The star Chi Virginis has ane of the most massive planets e'er detected, at a mass of 11.1 times that of Jupiter.
The sun-like star 61 Virginis has three planets: one is a super-Globe and 2 are Neptune-mass planets.
SS Virginis is a variable star with a noticeable red colour. Information technology varies in magnitude from a minimum of 9.six to a maximum of 6.0 over a menses of approximately one twelvemonth.[3]
Exoplanets [edit]
There are 35 verified exoplanets orbiting 29 stars in Virgo, including PSR B1257+12 (three planets), 70 Virginis (one planet), Chi Virginis (one planet), 61 Virginis (three planets), NY Virginis (2 planets), and 59 Virginis (one planet).
Deep-heaven objects [edit]
The shadow of the central black hole in the milky way Messier 87 in Virgo, obtained by the Event Horizon Telescope collaboration. This is the start direct image of a black pigsty.
Considering of the presence of a milky way cluster (consequently called the Virgo Cluster) within its borders 5° to 12° west of ε Vir (Vindemiatrix), this constellation is especially rich in galaxies.
Some examples are Messier 49 (elliptical), Messier 58 (spiral), Messier 59 (elliptical), Messier threescore (elliptical), Messier 61 (screw), Messier 84 (lenticular), Messier 86 (lenticular), Messier 87 (elliptical and a famous radio source), Messier 89 (elliptical) and Messier 90 (spiral). A noted galaxy that is non part of the cluster is the Sombrero Milky way (M104), an unusual screw galaxy. It is located virtually 10° due westward of Spica.
NGC 4639 is a face-on barred screw galaxy located 78 Mly from Earth (redshift 0.0034). Its outer arms have a high number of Cepheid variables, which are used as standard candles to decide astronomical distances. Considering of this, astronomers used several Cepheid variables in NGC 4639 to calibrate blazon 1a supernovae as standard candles for more distant galaxies.[iv]
Virgo possesses several galaxy clusters, 1 of which is HCG 62. A Hickson Meaty Group, HCG 62 is at a distance of 200 Mly from Earth (redshift 0.0137) and possesses a large fundamental elliptical milky way. It has a heterogeneous halo of extremely hot gas, posited to be due to the active galactic nucleus at the core of the central elliptical galaxy.[iv]
M87 is the largest milky way in the Virgo cluster, and is at a altitude of 60 Mly from Earth (redshift 0.0035). It is a major radio source, partially due to its jet of electrons being flung out of the galaxy by its central supermassive blackness pigsty. Because this jet is visible in several different wavelengths, it is of interest to astronomers who wish to notice black holes in a unique galaxy.[4] On April 10, 2019, astronomers from the Event Horizon Telescope project released an paradigm of its primal black hole; the showtime direct image of 1.[5] [6] [7] With a mass of at least 7.2 billion times that of the Sun, it is the most massive black pigsty within the immediate vicinity of the Milky Mode.[eight]
M84 is some other elliptical radio milky way in the constellation of Virgo; it is at a altitude of 60 Mly (redshift 0.0035) too. Astronomers have surmised that the speed of the gas clouds orbiting the core (approximately 400 km/southward) indicates the presence of an object with a mass 300 million times that of the sun, which is virtually likely a black hole.[4]
The Sombrero Galaxy, M104, is an edge-on spiral galaxy located 28 1000000 light-years from Earth (redshift 0.0034). It has a bulge at its center fabricated up of older stars that are larger than normal. It is surrounded by large, bright globular clusters and has a very prominent dust lane made up of polycyclic aromatic hydrocarbons.[4]
NGC 4438 is a peculiar galaxy with an active galactic nucleus, at a distance of 50 Mly from Earth (redshift 0.0035). Its supermassive black hole is ejecting jets of matter, creating bubbles with a diameter of upwardly to 78 ly.[4]
NGC 4261 also has a black hole xx ly from its center with a mass of one.2 billion solar masses. Information technology is located at a distance of 45 Mly from Earth (redshift 0.0075), and has an unusually dusty deejay with a diameter of 300 ly. Along with M84 and M87, NGC 4261 has potent emissions in the radio spectrum.[4]
Virgo is too habitation to the quasar 3C 273 which was the first quasar ever to exist identified. With a magnitude of ~12.ix, it is as well the optically brightest quasar in the heaven.
Mythology [edit]
Virgo as depicted in Urania's Mirror, a set of constellation cards published in London c.1825
Depiction of Virgo, c.yard
In the Babylonian MUL.APIN (c. 10th century BC), function of this constellation was known as "The Furrow", representing the goddess Shala and her ear of grain. One star in this constellation, Spica, retains this tradition every bit it is Latin for "ear of grain", i of the major products of the Mesopotamian furrow. For this reason the constellation became associated with fertility.[ix] The constellation of Virgo in Hipparchus corresponds to two Babylonian constellations: the "Furrow" in the eastern sector of Virgo and the "Frond of Erua" in the western sector. The Frond of Erua was depicted equally a goddess belongings a palm-frond – a motif that still occasionally appears in much later on depictions of Virgo.[10]
Early Greek astronomy associated the Babylonian constellation with their goddess of wheat and agronomics, Demeter.[ citation needed ] The Romans associated it with their goddess Ceres.[ citation needed ] Alternatively, the constellation was sometimes[ clarification needed ] identified as the virgin goddess Iustitia or Astraea, property the scales of justice in her paw (that now are separated equally the constellation Libra).[eleven] Another Greek myth from later, Classical times, identifies Virgo every bit Erigone, the daughter of Icarius of Athens.[12] Icarius, who had been favored by Dionysus and was killed by his shepherds while they were intoxicated later on which Erigone hanged herself in grief; in versions[ clarification needed ] of this myth, Dionysus is said to have placed the father and daughter in the stars as Boötes and Virgo respectively. Some other figure who is associated with the constellation Virgo was the spring goddess Persephone,[thirteen] [14] [xv] [xvi] the daughter of Zeus and Demeter who had married Hades and resided in the Underworld during summer.[17]
In the Poeticon Astronomicon past Hyginus (1st century BC), Parthenos ( Παρθένος ) is the daughter of Apollo and Chrysothemis, who died a maiden and was placed among the stars as the constellation.[18] Diodorus Siculus has an alternative account, co-ordinate to which Parthenos was the daughter of Staphylus and Chrysothemis, sister of Rhoeo and Molpadia (Hemithea). After a suicide try she and Hemithea were carried by Apollo to Chersonesus, where she became a local goddess.[xix] Strabo besides mentions a goddess named Parthenos worshipped throughout Chersonesus.[20]
During the Middle Ages, Virgo sometimes was associated with the Blessed Virgin Mary.[nine]
In Greek mythology, the constellation is besides associated with the daughter of Zeus, Dike the goddess of justice, who is represented holding the scales of justice.
