When was perseus constellation discovered

His astronomical catalogue, the New General Catalogue used in its abbreviated form NGC and numbered , lists nebulae and star clusters, These later became known as the Messier objects. The Constellation of Cassiopeia can be used to locate the double cluster of Perseus. The brightest member of the Perseus cluster is NGC The Messier Marathon The best time of year to view all Messier objects at the same time, providing night sky conditions are positive, is between mid to late March and early April.

Spiral Galaxies NGC a spiral galaxy, or lenticular galaxy is found in the northern circumpolar Constellation of Perseus. What is the Milky Way? Ptolemy listed the various constellations in his Almagest a book recording astronomical data.

The names of the Stars begin with a Greek letter starting with — Alpha 2. Giving the first Perseus Star name Alpha Persei The main stars of Cassiopeia are named by their apparent magnitude luminosity from the brightest to faintest: Alpha Persei Mirfak or Algenib — a bright multiple Star, and circumpolar star.

The shape of Perseus The Bright Stars If you look up and into the night sky you can imagine the recognizable outline of the Constellation of Perseus, as a man. This main constellation is made up of 17 main bright Stars Stars with Planets Perseus has 7 Star systems with exoplanets orbiting around them in the solar system but they are unlikely to be able to support life forms.

The furthest exoplanet discovered was actually in the Andromeda Galaxy, not in the Milky Way. FACT : An exoplanet also referred to as an extrasolar Planet is a planet that orbits a Star that is not located within our Solar System exoplanets do not orbit our Sun Nothing stands still in the sky. Planets are continually being discovered and lists updated.

Why and what is the purpose of Perseus? The Perseus celestial pole The celestial pole defines the poles of the celestial equatorial coordinate system. An object at the Celestial pole has a declination of 0 degrees. Navigational tools in the sky The many Constellations in the night sky were a useful navigation tool and guide as well as the subject of legends and myths.

Historical significance: the legends, and myths surrounding Constellation of Perseus Myths When it comes to the many recognized constellations in the sky, Perseus is one of the largest Constellations. However the origins of the earliest Constellations probably date back to prehistory. Greek mythology There are many Greek myths and legends surrounding the origin and names of the constellations.

The Constellation Perseus is identified as the outline of the body of Perseus, the Hero The other myth of how Perseus rescued Andromeda The myth begins with Cassiopeia, the wife of King Cepheus, of Ethiopia, who was a vain queen. Ancient associations with the constellations The Greeks, Romans and the Sumerians were all interested in the constellations in the sky.

The Sumerians were the first literate civilization of the Ancient Mesopotamia an area occupying parts of Turkey and the Syria of today, Iraq, Iran The Sumerian civilization was not unified like the ancient Greek or Roman civilizations it was bonded by a common attitude. The Mesopotamian civilization the first known civilization identified constellations like Perseus FACT : The ancient lands of the Mesopotamians now stretches across Turkey, Syria, Iraq and Kuwait Perseus and the other constellations in the sky were not only the subject of legends but they had a practical use too.

What is the difference between a constellation and an asterism? An asterism is a more vague assembly of stars than a recognized constellation. When the embers from the meteor shower cool they appear under plants as earth. Fun Facts about Constellations — Did you know that? Mirfak or alpha Persei the brightest star in Perseus hosts an exoplanet and is times bigger than the Sun.

Constellations like Perseus are not part of our Solar System; they are groups of stars that appear to form shapes that are visible with the naked eye from Earth.

The largest Constellation is called Hydra and the smallest Constellation is called Crux The Sun does not belong to any constellation. A Constellation does not actually exist as a fixed object, it is a group of bright stars that happen to be in a random place and are light years apart and ever moving.

We see the pattern of their presence. Red Dwarf is not a Dwarf Planet it is a Star. What is the celestial sphere? In astronomy and navigation terms, the celestial sphere is imaginary. This virtual sphere has a large radius that is concentric with Earth. What prevents us seeing the Stars and Constellations in the night sky?

Will the Constellations change over time? The Constellations are continually on the move.

In addition, it usually has very high levels of iron, the particles of which align themselves with the galactic magnetic field, which in turn causes the light to be polarized. On September 18th, , in a galaxy million light-years distant astronomers detected what turned out to be the second largest supernova ever recorded by modern scientists, being more than one hundred times more powerful than a typical supernova.

Perseus boasts one of the most impressive meteor showers of any constellation, The Perseids , which occur during a nice warm time of the year in the northern hemisphere, thus encouraging many people to go outside and take a look.

Interestingly, although The Perseids and the September Perseids seem to appear from the same radiant, the two showers are separate and are formed from different comets.

Home About. News Ticker. Related Articles. The star is a suspected member of the Alpha Persei Cluster, but has a higher proper motion than other members. Omega Persei belongs to the spectral class K1III and is approximately light years distant from the solar system.

Pi Persei belongs to the spectral class A2Vn and has a visual magnitude of 4. It is light years distant from the Sun. It has an apparent magnitude of 4.

The star is now usually referred to as HR X Persei is a double star system with a blue main sequence star spectral type O9. It has an apparent magnitude of 6. The star is notable because it is orbited by a neutron star, X Persei B. A neutron star is a hot remnant, composed almost entirely of neutrons, of a massive star that underwent a gravitational collapse during a Type II, Ib or Ic supernova event.

Nova Persei , also known as GK Persei, was a bright nova that occurred in With a peak magnitude of 0. GK Persei subsequently faded to magnitude 12 or 13, but had occasional outbursts of 2 to 3 magnitudes. In the last 30 years, the outbursts have become pretty regular and last about two months every three years or so, which makes GK Persei resemble not a typical nova, but a dwarf nova-type cataclysmic variable star.

V Persei is a young star belonging to the spectral class K3V, located in the young open star cluster IC The star is occulted by an unknown body every 4. The Perseids are probably the best known of all meteor showers.

They can be seen every summer, from mid-July to late August in the northern hemisphere. The meteor shower peaks every year around August 13, when the rate of meteors can reach over 60 per hour, which usually happens in the hours just before the dawn.

The Perseid meteor shower is associated with the Perseus constellation because its apparent point of origin, also called the radiant, is located in the constellation. The meteor shower has been observed for some years or so, with first reports coming from the Far East. The shower is also known as the tears of St. Lawrence in some Catholic countries, as it coincides with the date of St. The Perseids are associated with the comet Swift-Tuttle, a periodic comet that has an orbital period of about years.

The comet was first discovered by Lewis Smith and Horace Parnell Tuttle, two American astronomers who independently observed it in July The comet has a solid nucleus 26 kilometres across and is the parent body of the Perseid meteor shower. It leaves a line of debris known as the Perseid cloud along its orbit.

Most of the dust in the cloud is believed to be about a thousand years old. Messier 34 is an open cluster with a visual magnitude of 5. It is between and million years old. It contains about stars and is seven light years in radius. In good conditions, it appears as a blurry patch slightly north of the line from Algol to Almach , Gamma Andromedae. The Little Dumbbell Nebula is a planetary nebula in Perseus. It has a visual magnitude of The first person to recognize it as a planetary nebula was the astronomer Heber Doust Curtis.

The Little Dumbbell Nebula is 2. The nebula was originally assigned two catalogue numbers, NGC and NGC , because it was believed to consist of two different emission nebulae. The Alpha Persei Cluster is an open star cluster in Perseus. It contains several blue stars, the brightest one of which is Mirfak, Alpha Persei, a white-yellow second magnitude giant.

Other bright members of the cluster include Delta, Epsilon, and Psi Persei. The estimated age of the cluster is between 50 and 70 million years. The Alpha Persei Cluster is between and light years distant and has a visual magnitude of 1. The Perseus molecular cloud is a giant molecular cloud, or stellar nursery, located about light years from the solar system.

The Perseus Cluster is a cluster of galaxies located in Perseus constellation. It is home to thousands of galaxies and one of the most massive objects known in the universe.

It is about This idyllic scene, packed with glowing galaxies, has something truly remarkable at its core: an untouched relic of the ancient Universe. This relic can be seen in the large galaxy at the centre of the frame, a lenticular galaxy named NGC This galaxy is a member of the famous Perseus Cluster — one of the most massive objects in the known Universe, located some million light-years from Earth. Its host is the elliptical galaxy NGC The galaxy is 2.

It is classified as a Fanaroff and Riley class 1 radio galaxy, one with the brightest points in the radio emission located toward the centre. They are 7, and 6, light years distant respectively and relatively close to each other in space. Their respective ages are estimated at 3.

The Double Cluster has a combined apparent magnitude of 4. NGC lies to the west and has a visual magnitude of 5.

Each cluster contains more than supergiant stars. The hottest main sequence stars in the clusters belong to the spectral class B0. NGC is a reflection nebula in Perseus, located in the Perseus molecular cloud. The nebula is approximately light years distant. The Chandra data reveal 95 young stars glowing in X-ray light, 41 of which had not been seen previously using Spitzer because they lacked infrared emission from a surrounding disk. NGC is a spiral galaxy. It is notable for being home to supernova SN gy, a supernova event in that was the second brightest object in the observable universe.

The galaxy has an apparent magnitude of The California Nebula got its name because it resembles the outline of California on a map in long exposure photographs. It is an emission nebula in Perseus, about light years distant.

It has a visual magnitude of 6. The nebula is about 2. It was discovered by the American astronomer E. Barnard in
