It is also an irregular variable star, its brightness changing from magnitude 2. There are also 2 class G stars further away that may or may not be physically related to the main pair. The brighter of the bright pair is on its way to becoming a much larger giant, and will eventually expand to a radius of a quarter the distance that now separates the two stars, streams of matter running from the brighter to the dimmer creating quite a sight from the smaller pair.
Eventually the bright star of the brighter pair will fade to become a white dwarf, this double perhaps looking something like Sirius does today.
Next up? Located light years away, Enif is a cool star for more than one reason! To begin with, Enif is orange class K K2 supergiant star whose stellar temperature only averages about degrees Kelvin.
What makes Enif so cool is that it is very unpredictable. According to records, in Enif had a flare event which caused it to brighten 5 times more than its normal stellar magnitude! Keep your binoculars handy, because following the trajectory from Theta to Epsilon just another third of the way will bring you to awesome globular cluster — Messier 15 RA It ranks third in variable star population and M15 is perhaps the oldest and most dense of all globulars located in the Milky Way Galaxy.
Its compact central core may be the result of mutual gravitational interaction, or it could contain a dense, supermassive object — a black hole. One thing we do know that M15 contains is a planetary nebula known as Pease 1 — only four known planetary nebulae in Milky Way globular clusters! Another curiosity is M15 also contains 9 pulsars, the remnants of ancient supernova explosions leftover from its youthful beginnings.
While you can easily see M15 with binoculars, even a small telescope can begin resolution on this great deep sky object! This magnitude 10 jewel displays a bright nucleus and hazy frontier over its generous 3. At magnitude 10 and a huge 6. The star is cooler than our Sun, having temperatures of around 4, K. It is part of the Ursa Major Group of moving stars.
Just like Pi 1 Pegasi, P 2 Pegasi has exhausted its supply of hydrogen, and it has started to cool down, and expand. This star is million years old, and it is still hotter than our Sun, having temperatures of around 6, K. The constellation of Pegasus hosts numerous interesting deep-sky objects. NGC , also known as Caldwell 30, is an unbarred spiral galaxy located at around 40 million light-years away from us. It has an apparent magnitude of NGC was discovered in by the famous astronomer, William Herschel.
NGC has a diameter of around , light-years. NGC , also known as the Fried Egg Galaxy, is a face-on unbarred spiral galaxy located at around This galaxy is unusual since it contains a ring, but no bar. This quasar is located at around 8 million light-years away from us, while the lensing galaxy is located at million light-years away.
The quasar has an apparent magnitude of This group was discovered in by Edouard Stephan. It is the most studied compact group of galaxies, and its brightest member is a false member. NGC is a spiral galaxy located at around 39 million light-years away from us. NGC is a highly distorted barred spiral galaxy located at around million light-years away.
NGC has an apparent magnitude of NGC is a lenticular galaxy located at around NGC is an unbarred spiral galaxy located at around 50 million light-years away from us. NGC is a disturbed spiral galaxy located at around This galaxy has recently experienced intense star formation activity and may be classified as a starburst galaxy. NGC 23 is a spiral galaxy located at around This galaxy was discovered by William Hershel in NGC , also known as Caldwell 43, or UGC 8, is a spiral galaxy located at around 40 million light-years away from us.
The Propeller Galaxy, designated as NGC , or Caldwell 44, is an unbarred spiral galaxy located at around million light-years away from us. The galaxy appears to be around , light-years in diameter. The two galaxies have an apparent magnitude of There is only one meteor shower associated with the constellation of Pegasus, namely the July Pegasids.
The July Pegasids occur between the 7 and 13 of July. It is a weak meteor shower, which peaks around the 9 th of July, having a ZHR of only 3 meteors per hour. The constellation of Pegasus is associated with the myth of the white-winged horse that sprang from the neck of the Gorgon Medusa, when the hero Perseus beheaded her, in Greek mythology.
Athena turned Medusa into a monster, that had snakes instead of hair, and her face was so abhorring that anyone who gazed at her, would turn into stone. Perseus, against all odds, managed to kill Medusa by cutting her head, and this is when Pegasus, and the warrior Chrysaor, sprang from her neck — both of them being the offspring of Poseidon.
When Pegasus was born, he flew away to Mount Helicon in Boeotia, where the Muses lived, and he befriended them. Pegasus created a spring by striking the ground with his hoof.
Those that drank from this spring would be blessed with the gift to write poetry. Another famous myth associated with Pegasus is that involving another Greek hero, namely Bellerophon. Bellerophon was sent by King Iobates of Lycia to kill the Chimaera, a monster that could breathe fire. Bellerophon found Pegasus and tamed him using a golden bridle given to him by the goddess Athena. Bellerophon then rode Pegasus into the sky, and swooped down on the Chimaera, killing the monster with his arrows and lance.
After this huge success and other heroic deeds performed for King Iobates, Bellerophon began to believe he was entiltled to join the gods on Mount Olympus. He tried but failed to reach Mount Olympus, as he fell off from Pegasus back to Earth.
Pegasus managed to reach Olympus, where the supreme Greek god Zeus used the horse to carry his thunder and lightning. Zeus eventually placed Perseus among the constellations. The constellation of Perseus is depicted with only the top half of the horse. Pegasus Constellation. Home » Constellations » Pegasus Constellation. Pegasus is now among the 88 modern constellations, where it holds the title of the 7 th largest constellation in the sky, stretching for around square degrees.
Pegasus contains only one Messier object, the globular cluster Messier 15, which is located at around 33, light-years away from Earth. There is only one meteor shower associated with the constellation of Pegasus, the July Pegasids. There is one famous asterism in Pegasus, the Great Square of Pegasus, which is formed out of the three brightest stars in the constellation, namely Markab, Scheat, Algenib, and the star Alpheratz, which is the brightest star in the constellation of Andromeda.
There are plenty of interesting bright stars in Pegasus, among them, the brightest star Enif, the second-brightest, Scheat, the third-brightest, Markab, the fourth-brightest Algenib, the red dwarf, and white dwarf star system designated as AG Pegasi, the pulsating Phi, and Psi Pegasi red giants, the white star Salm, or the first discovered Sun-like star to host an exoplanet, 51 Pegasi, among many others.
Location The constellation of Pegasus is located in the northern celestial hemisphere. Pegasus was mortal, though, but because of its lifelong service to Perseus and Andromeda, on the last day of its life he was made into a constellation. If you drew an imaginary line through Alpheratz and past Markab for a distance about three-quarters the width of the Great Square, you will find the Andromeda Galaxy.
The Andromeda Galaxy M31 has an apparent visual magnitude of 3. The Andromeda Galaxy has more than a trillion stars, while the Milky Way galaxy pales in comparison with between and billion stars. In this constellation can be found Messier 15 M15 , which at around 12 billion years old is one of the oldest globular clusters ever discovered.
It is situated 33, light-years away, is around light years wide, and contains more than , stars, including variable stars, pulsars and a double neutron star system, as well as a planetary nebula. As you may know, there are around billion galaxies in the observable universe and 70 sextillion stars 70,,,,,,, To put the survey into perspective, remember that each one of the disks seen in the SDSS image is a galaxy similar to our own, and it would take 30, to , years for light to cross each individual fuzzy patch.
In the center of the image is the galaxy NGC ; surrounding it are four identical quasars.
