When was andromeda constellation discovered

Located north of the celestial equator, this constellation is part of the family of Perseus, Cassiopeia, and Cepheus. Like many constellation that have come down to us from classical antiquity, the Andromeda constellation has deep roots, which may go all the way back to ancient Babylonian astronomy.

Derived from Greek mythology, Andromeda was the daughter of Cassiopeia and Cepheus — the king and queen of ancient Aethopia modern day Ethopia. Unfortunately, her mother was so vain that she thought herself to be more beautiful than the daughters of Nereus, a god of the sea, which angered the sea god Poseidon. To punish the mother, Andromeda was chained to a rock of the coast as a sacrifice for a sea monster, Cetus another southern constellation.

Andromeda escaped this fate, thanks to the intervention of Perseus — the greatest Greek hero and slayer of monsters before Heracles. For rescuing her, he demanded Andromeda become his wife, which her parents happily consented to. The two married, had nine children together, and founded the kingdom of Mycenae and its Persideae dynasty. The celestial mapping aka. Andromeda is also associated with the Mesopotamian creation story of Tiamat, the goddess of Chaos.

According to the legend, Tiamat bore many demons for her husband, Apsu, the god of freshwater. However, she eventually decided to destroy them as part of a war between the older and youner gods.

Eventually, Marduk — a younger-generation god and the patron deity of the city of Babylon — killed her. He then used her body to create the constellations as markers of time for humans.

Several of the neighboring constellations Perseus, Cassiopeia, Cetus, and Cepheus also represent characters in the Perseus myth. This is a massive galaxy with an Andromeda size diameter of about , light-years 7. Andromeda has about 14 dwarf galaxies orbiting around it, known as satellite galaxies. The amazing Triangulum Galaxy in the constellation Triangulum is also a satellite of the Andromeda Galaxy 8.

If you are looking for a great nebula in Andromeda, NGC is a massive star cloud in the Andromeda galaxy. This bright star cloud is also known as M31 and is one of the largest star-forming regions in the Local Group of galaxies. Astronomers detect star-forming regions by the telltale reddish emission from clouds of ionized hydrogen gas.

The distance to the Andromeda galaxy is about 2. The diameter of the NGC Andromeda galaxy size is about light-years 9. It is the brightest globular cluster in the Local Group of galaxies. Mayall II has an apparent visual magnitude of The largest globular cluster in our milky way is Omega Centauri. Astronomers think that it contains a black hole in its center. Nicholas Mayall discovered the cluster in and gave it its name Messier 32 is a dwarf elliptical galaxy that lies about 2.

Messier 32 was the first elliptical galaxy ever discovered and is also one of the satellites galaxies of Andromeda. M32 is fairly bright, and you can see it using a home telescope. M32 contains predominantly old stars, with no active star formation.

It has a supermassive black hole in its center. M is about 2. It is an elliptical dwarf galaxy with 8 globular clusters in a halo that surrounds it. Messier was observed and described by Charles Messier in It was also found by Caroline Herschel a decade later.

Her discovery was documented by her brother William Herschel in Messier may contain a supermassive black hole at its center. NGC , also known as Caldwell 28, is an open cluster. It lies about 1, light-years away and has an apparent visual magnitude of 5. NGC is bright and you can see it with binoculars or a telescope for even better views. It is a large, sprawling cluster.

There are at least 70 NGC is an edge-on spiral galaxy that lies about It is close to the star Almach, Gamma Andromedae, on the east side. You can see NGC using a home telescope and it is an amazing sight. The galaxy has an apparent visual magnitude of NGC discovery was in by William Herschel. The Blue Snowball Nebula is a sight not to miss, but unfortunately, you can only see it with a very powerful telescope! It is a planetary nebula with an apparent visual magnitude of 8.

The blue light comes from the central star, which is a bluish dwarf star with a very hot temperature of around 75, K. Astronomers believe the Andromeda galaxy distance of Snowball Nebula is around 2, to 6, light-years NGC 90 lies about GC 90 has an apparent visual magnitude of It has a significant shape of two distorted, elongated spiral arms. NGC 93 has a visual magnitude of The shapes are most likely caused by the interaction of gravitational forces between the two galaxies.

Mitchell Exoplanets are planets that revolve around stars, other than our star, the Sun. Exoplanets excite astronomers as they may offer conditions similar to those in our Solar System, with the possibility of life. There are many planets in the Andromeda galaxy. Read on for more facts!

Upsilon Andromedae is also known as Titawin. It is 44 light-years away from earth. This star is an interesting celestial object, ranked 21st on the list of the top target stars for the NASA Terrestrial Planet Finder mission. It has 4 Andromeda galaxy planets orbiting around it. One of them is Upsilon Andromedae d, a gas giant exoplanet with a mass of 4. It takes 3. HD is also known as Buna. It is a yellow star about light-years away.

Orbiting the star is an exoplanet called Abol, or HD b. Many exoplanets get their name from members of the public who participate in the NameExoWorlds campaign by Ethiopia, established during the th anniversary of the IAU. Abol is the first of three rounds of coffee in the Ethiopian traditional coffee ceremony. HD b is a gas giant with a mass of 5. It takes 2. Kappa Andromedae has one exoplanet known as kappa And b. It has an orbital period of about years. Kappa Andromedae is a blue subgiant star that lies about light-years away from earth.

The star indicates the right hand of the Andromeda constellation. HAT-P is a yellow-white star that lies about light tears away. It has one exoplanet known as HAT-P b. HAT-P b is a gas giant with a mass of 0. It flies around its star, with an orbit of only 2.

Its discovery was in Meteor showers occur when Earth crosses the orbital path of a comet. This creates a spectacular show, often known as shooting stars. The Andromedids is not a spectacular shower in recent times. It was seen again in and In , a German skywatcher, Wilhelm von Biela, tracked it and discovered that it orbits the sun every 6. This is a significant observation as very few comets have had their orbits successfully calculated. It has an apparent magnitude of 2.

It is 2, times more luminous than the Sun. The fainter companion star, Gamma 2 Andromedae, is itself a binary star, consisting of fifth and sixth magnitude white dwarf stars. The brighter component is also a double star. Delta Andromedae is a double star with an apparent magnitude of 3.

The brighter component is a K-type giant, while the dimmer companion is either a G-type main sequence star or a white dwarf. Iota Andromedae is a B-type main sequence dwarf, bluish white in colour. Upsilon Andromedae is another binary star system in the Andromeda constellation, composed of a yellow-white dwarf and a fainter red dwarf. The primary star, Upsilon Andromedae A, has four planets in orbit, presumed to be Jovian planets similar to Jupiter. With an age of 3. Upsilon Andromedae B is a red dwarf located AU from the primary star.

It is both less massive and less luminous than the Sun. Upsilon Andromedae is 44 light years distant. Adhil, or Xi Andromedae, is also a double star. Its spectral class is G9. With an apparent magnitude of 3. It is an orange K-type giant light years distant. Even though Ptolemy originally included the star in the Andromeda constellation, Johann Bayer later moved it to Perseus as Upsilon Persei. English astronomer John Flamsteed later moved it back to Andromeda, where it has stayed to this day.

Mu Andromedae is a white A-type dwarf located approximately light years from Earth. Pi Andromedae is another binary star, approximately light years distant. The primary component has an apparent magnitude of 4. R Andromedae is a Mira -type variable star that appears about four degrees southwest of the Andromeda Galaxy. Its brightness varies between 5. RX Andromedae is a Z Camelopardalis-type variable star.

Its brightness varies between magnitude Groombridge 34 is also a binary star, consisting of two red dwarfs. Only In the past, before astronomers knew what it was, the galaxy was referred to as the Great Andromeda Nebula.

Andromeda Galaxy is the closest spiral galaxy to the Milky Way and the farthest object in the night sky visible to the unaided eye. It has an apparent magnitude of 3. The galaxy contains a trillion stars. This is significantly more than the Milky Way, which has approximately billion stars.

Only the brightest central region of the Andromeda Galaxy is visible through a small telescope but, in a larger telescope, the Andromeda Galaxy is about six times as wide as the full Moon. Andromeda belongs to the Local Group of galaxies, along with the Milky Way, Triangulum Galaxy Messier 33 , and 30 or so smaller galaxies. Andromeda is the largest of the group.

Its mass is estimated to be roughly equal to that of the Milky Way Galaxy, with which it is expected to collide in about 4. Andromeda has at least 14 dwarf galaxies orbiting it, including M32 and M Other satellite galaxies are considerably fainter and were not discovered until the s. The Triangulum Galaxy M33 , the famous spiral galaxy in the constellation Triangulum , is also believed to be a satellite of the Andromeda Galaxy. Star cloud NGC NGC is a star cloud in the Andromeda Galaxy.

It is the brightest star cloud in M31 seen from Earth and one of the largest star forming regions in the Local Group of galaxies.
