The most famous myth involving Pegasus is the one of Bellerophon, the hero who was sent by King Iobates of Lycia to kill the Chimaera, a monster that breathed fire and was devastating the king’s land. Athena turned Medusa’s hair into snakes and made her face so ugly that anyone who looked at her immediately turned to stone. It has two visual companions, a magnitude 11.6 star 68 arc seconds away and an 11th magnitude star 177 arc seconds away. This star is only 47% more massive than our Sun, its radius is 34% greater, and it is hotter than our Sun, having temperatures of around 7,430 K. The debris disk surrounding this system extends to around 2,000 AU – the equivalent of Pluto’s orbit. 1. According to legend, the horse had magical powers, his hooves could dig out a spring, for example. The Andromeda Galaxy, also designated as Messier 31, can be found between the Great Square and Cassiopeia’s W asterism. There is a famous asterism in Pegasus, which is named the Great Square of Pegasus. Stephan’s Quintet–A Galaxy Collision in Action Stephan’s Quintet, a compact group of galaxies discovered about 130 years ago and located about 280 million light years from Earth, provides a rare opportunity to observe a galaxy group in the process of evolving from an X-ray faint system dominated by spiral galaxies to a more developed system dominated by elliptical galaxies and bright X-ray emission. These interactions have sparked a frenzy of star birth in the central pair of galaxies. The phenomenon of gravitational lensing is one of the effects predicted by the general theory of relativity and was originally postulated by Albert Einstein once he realized that gravity would be able to bend light. Most of the quintet is too far away even for Hubble to resolve individual stars. Algenib is also the most distant star from this asterism, located at around 390 light-years away from us, being situated in the southeast corner of the asterism. The brightest star in the constellation is Enif, Epsilon Pegasi, with an apparent magnitude of 2.399. Their apparent magnitudes are 14.4 and 13.9 respectively. The traditional name, Scheat, comes from the Arabic Al Sā’id, which means “the upper arm.”. Medusa was a beautiful woman before she was cursed by the goddess Athena after she was defiled by the sea god Poseidon, in Athena’s temple. The neighboring constellations are Aquarius, Delphinus and Pegasus. The quasar is about 8 billion light years distant from the Sun, while Huchra’s lens lies only 400 million light years away.

Pegasus is visible in both the Northern and Southern hemispheres. Homam, designated as Zeta Pegasi, is a bright star located at around 204 light-years away from our Solar System. At the personal level there are the spiritual implications involved for humanity adjusting to these changes. NGC 23 is a bright spiral galaxy in Pegasus. The quasar is called the Einstein Cross because as many as four images of the quasar appear around the galaxy in the foreground as a result of strong gravitational lensing. Notoriously wild and free-roaming, Pegasus was finally tamed by one of the greatest Greek heroes, Bellerophon. Perseus was sent to kill Medusa by King Polydectes of Seriphus, who was the brother of Dictys, the man who took Perseus and his mother Danaë in and raised Perseus as his own son. The ring structure in NGC 7742 may be the result of a merger with a small, gas-rich dwarf galaxy, and the extremely bright central region and some of the gas rotating in the opposite direction are some of the features that suggest this may have been the case. This star has around 472% of our Sun’s radius, and it is very hot, with surface temperatures recorded at around 9,765 K.

These stars are less than 10 million years old and have not yet blown away their natal cloud. Equuleus is the second smallest constellation in the night sky, after Crux (the Southern Cross). Pegasus, in Greek mythology, a winged horse that sprang from the blood of the Gorgon Medusa as she was beheaded by the hero Perseus. Pegasus contains a Messier object – Messier 15 (NGC 7078, Cumulo de Pegaso) – and has nine stars with confirmed planets. Its traditional name, Enif, comes from the Arabic word for “the nose.” The star marks Pegasus’ muzzle. Global warming, sea level rise, increased frequency and intensity of storms. with the other constellations.
