>TOP 15 CONSTELLATIONS WE SHOULD KNOW

A constellation is a group of stars that forms an imaginary outline or pattern on the celestial sphere, typically representing an animal, mythological person or creature, a god, or an inanimate object. The origins of the earliest constellations likely go back to prehistory.There are 88 official constellations. But astronomers haven't made up new constellations for hundreds of years! When new stars are discovered, they are considered to be a part of whatever constellation they are closest to.

Aquarius

Aquarius constellation is located in the southern hemisphere. It is one of the 12 zodiac constellations. The constellation’s name means “the water-bearer” (or “cup-bearer”) in Latin and its symbol is ♒, which represents water. Aquarius lies in the region of the sky which is sometimes referred to as the Sea, because it contains a number of other constellations with names associated with water; Pisces (the fish), Eridanus (the river), and Cetus (the whale), among others. Like other zodiac constellations, Aquarius was catalogued by the Greek astronomer Ptolemy in the 2nd century. Aquarius contains the famous supergiant star Sadalsuud (Beta Aquarii) and a number of notable deep sky objects: the globular clusters Messier 2 and Messier 72, the asterism Messier 73, the Aquarius Dwarf Galaxy, Atoms for Peace Galaxy (NGC 7252) and two well-known nebulae: the Saturn Nebula and the Helix Nebula.

While one of the biggest, most famous, and oldest named constellations, Aquarius is faint and often hard to find/see. In Greek mythology, Aquarius represented Ganymede, a very handsome young man. Zeus recognized the lad’s good looks, and invited Ganymede to Mt. Olympus to be the cupbearer of the gods. For his service he was granted eternal youth, as well as a place in the night sky.

Despite its prominent position and large size, you can see that Aquarius doesn’t really have defining features, nor does it contain any bright stars. The protruding line to the right is Aquarius’s right arm, with the large downward shape being a combination of the water flowing down out of the vase and his right leg. While not the entire constellation, what’s drawn above is what you’re most likely to see in the night sky. You won’t see this one in the city; you’ll need a dark sky to find the cupbearer.

This constellation lies in the Milky Way band, and its most prominent star is Altair, which is actually one of the closest naked eye stars to the earth. The top portion of Aquila forms a shallow inverted “V,” with Altair nearly the point. This represents the head and wings of the eagle. A line then descends from Altair, which forms the body of the eagle.

Aquila

Aquila constellation is located in the northern sky, near the celestial equator. The constellation’s name means “the eagle” in Latin. The constellation represents the eagle of the Roman god Jupiter in mythology. It was first catalogued by the Greek astronomer Ptolemy in the 2nd century. Aquila is home to two very famous stars, Altair and Tarazed, as well as to several interesting deep sky objects: the planetary nebulae NGC 6803, NGC 6804, NGC 6781 and the Phantom Streak Nebula (NGC 6741), the open clusters NGC 6709 and NGC 6755, and the dark nebula B143-4.

Aquila was the eagle that in Greek mythology actually bore Ganymede (Aquarius) up to Mt. Olympus. The eagle was also the thunderbolt carrier for Zeus.

The top portion of Aquila forms a shallow inverted “V,” with Altair nearly the point. This represents the head and wings of the eagle. A line then descends from Altair, which forms the body of the eagle. Look towards the southern sky in the late summer, near the Milky Way band, for Aquila.

Aries

Aries constellation is located in the northern hemisphere. Its name means “the ram” in Latin. The symbol for the constellation is ♈ and it represents a ram’s horns. The constellation is usually associated with the story of the Golden Fleece in Greek mythology. Like other zodiac constellations, Aries was first catalogued by the Greek astronomer Ptolemy in the 2nd century. Aries contains several notable deep sky objects, among them the unbarred spiral galaxy NGC 772 and the dwarf irregular galaxy NGC 1156.

While many constellations have gone through various iterations of mythological stories, Aries has always been the ram. This constellation is one of 12 constellations that form the zodiac — the constellations that straddle the sun’s path across the sky (known in scienctific terms as the ecliptic). In ancient times, that gave the constellations of the zodiac special significance. In Greek mythology, Aries is the ram whose fleece became the Golden Fleece. The Golden Fleece is a symbol of kingship and authority, and plays a significant role in the tale of Jason and the Argonauts. Jason is sent to find the fleece in order to rightfully claim his throne as king, and with some help from Medea (his future wife), finds his prize. It’s one of the oldest stories in antiquity, and was current in Homer’s time.

Aries is formed by just 4 (sometimes 5) visible stars, which create a line from the ram’s head (the lowest point in the image above) and down its back. Hamal is the largest and most visible star, and is classified as an orange giant.
