When can i see pegasus
Locate it via the southern edge of the Great Square. A mag. A mm scope shows NGC as having a high surface brightness. Next, we head north to find the barred spiral galaxy NGC The easiest locator is mag. Once found, drop south from the star by 3. A mm scope shows a 3. Our final targets mark the start of the NGC catalogue. NGC 1 and 2 are two spiral galaxies appearing close to one another in the northeast corner of the Great Square.
NGC 1 is an intermediate spiral. Its surface brightness is low, approaching 14th magnitude, but it has a bright concentrated core. The apparent diameter of NGC 1 is around 45 arcseconds. NGC is an elliptical galaxy in Pegasus. It is 1. NGC is an unbarred spiral galaxy in Pegasus, seen face-on. The galaxy is notable for having a ring, but no bar, which would normally produce the ring structure in the galaxy.
The ring structure in NGC may be the result of a merger with a small, gas-rich dwarf galaxy, and the exceptionally 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. NGC has a visual magnitude of NGC is a spiral galaxy with a visual magnitude of The galaxy was discovered by the German-born British astronomer William Herschel in It has a similar structure and size to the Milky Way.
NGC is an unbarred spiral galaxy with an apparent magnitude of It is 3. The galaxy is a gas-poor system. It has several rings of stars of which the outermost is most prominent and contains most of the gas and star forming activity in NGC NGC is a disturbed spiral galaxy with a visual magnitude of It is a starburst galaxy; one that has recently experienced intense star forming activity.
The galaxy is approximately million light years distant. NGC 23 is a bright spiral galaxy in Pegasus. The galaxy lies approximately million light years from the solar system. 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.
The lensing effect is a result of spacetime around massive objects such as black holes or galaxy clusters being curved, which allows rays of light from a source located in the background to be bent. The image of the background source can be distorted and magnified in the process. The photograph shows four images of a very distant quasar which has been multiple-imaged by a relatively nearby galaxy acting as a gravitational lens.
The angular separation between the upper and lower images is 1. 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.
The exact location of the quasar is at 22h40m NGC is a spiral galaxy in Pegasus seen edge-on. The galaxy is sometimes called the little sombrero because of its resemblance to the Sombrero Galaxy Messier in Virgo constellation. NGC is a barred spiral galaxy. It is classified as a Seyfert galaxy undergoing star forming activity in the core and outer spiral arms. However, this galaxy, nicknamed the Propeller galaxy, emits a jet of radiation in radio wavelengths that bends in the opposite direction to the stars and dust in the arms of the galaxy.
Astronomers think that the radio jet was put into its bizarre backward spin after the Propeller galaxy merged with another galaxy. The Propeller galaxy is an interesting subject for several other reasons as well. The galaxy has also been the home to two recent supernovae, one witnessed in and the other in NGC 1 is a spiral galaxy in Pegasus, about 90, light years in diameter.
When the catalogue was compiled, objects were arranged by right ascension, and NGC 1 had the lowest right ascension at the time 00h07m Coordinates have shifted since and this is no longer the case. This makes it the seventh largest constellation in the night sky. It is bordered by Andromeda to the north and east, Lacerta to the north, Cygnus to the northwest, Vulpecula, Delphinus and Equuleus to the west, Aquarius to the south and Pisces to the south and east.
Pegasus is one of the 48 constellations listed by the Greek astronomer Ptolemy in the second century. It represents the famous winged horse in Greek mythology.
Curiously, the constellation Pegasus only represents the top half of the horse. In some depictions, the horse is shown rising out of the water.
Pegasus was a white winged horse born from the blood of the gorgon Medusa after she was beheaded by Perseus. He served the god Zeus as the carrier of his lightning bolts. M15 is one of the most densely packed clusters in the Milky Way galaxy. NGC is a spiral galaxy within Pegasus that is between 36 million to 46 million light-years from Earth.
In , astronomers spotted a supernova in this galaxy that released more hydrogen and heavier elements than expected , shortly before it exploded. Michael J. Brown, an observational astronomer at Monash University in Australia, wrote that NGC is close to the Milky Way in shape , which makes the galaxy an interesting object when astronomers make comparisons with our own neighborhood.
The Einstein Cross, a quasar , is an excellent example of gravitational lensing — the process by which distant objects are magnified by the gravity of closer objects.
The quasar is about 8 billion light-years from Earth and sits behind a galaxy that is million light-years away.
