Pisces is one of the thirteen constellations of the zodiac. This means that it lies along the path the Sun travels in the sky during the year. The March equinox is currently located in Pisces. However, due to procession of the earth's axis, it is slowly drifting towards Aquarius. It is one of the constellations first cataloged by the Greek astronomer Ptolemy in the second century.
The constellation is represented as a pair of fish facing in opposite directions, connected at the tail by a common star. In ancient times, the two fish were shown swimming together. In Greek mythology, the two fish represent the goddess Aphrodite and her son Eros. It was believed that they transformed into fish in order to escape the monster Typhon. Typhon was sent by Gaia, the Earth mother, to defeat the gods. Pan saw the monster coming and turned himself into a goat-fish and jumped into the river Euphrates to escape.
It is also called Alrescha "the cord" as it illuminates the spot where it appears that the tails of the two fish are tied together. It is the 31st closest star system and the nearest single white dwarf to the sun, at just Pisces also contains a Messier object — which are galaxies, nebulae and star clusters recorded by 18th Century French astronomer Charles Messier. Messier 74 is a spiral galaxy located between the stars alpha Arietis and eta Piscium.
Two years later, researchers announced that data from those observations showed the dwarf galaxies used to be by themselves , but over time they moved to a nearby group of galaxies — a process that accelerated star formation. Researchers said the study of Pisces A and Pisces B can also shed light on what dwarf galaxies today may have looked like in the ancient past. Researchers looking at the galaxy NGC announced a huge explosion there in , which likely came from a black hole.
They ruled out a supernova star explosion event as the researchers saw five locations with bright radio emissions near the galaxy's core. Several exoplanets have also been found in the constellation.
In , researchers found a world called GU Pisces b that orbits an incredible 2, times the Earth-sun distance, which means the planet takes roughly 80, Earth years to go around its star once.
