How to see the constellations in the sky
The constellations we recognize today have seen many changes over the millennia of human history. Some have their origins lost in the mists of time and others are more recent in our history.
What is the oldest constellation? No one really knows, but some are very, very old. The Big Dipper is believed to be one of the oldest, dating back to when the Ice Age took over the land. This constellation is known to the native peoples of Siberia and Alaska, suggesting that this constellation was known before the ice melted and broke the land bridge between the two continents, creating the Bering Strait.
The ancient Egyptians had their own constellations that can be placed at the end of the last Ice Age as well. Its name for the bright star Vega was "The Vulture Star".
The ancient Babylonians (around 5600 a. C.) created some constellations, but also used some previously named ones. Because they kept accurate and detailed records of celestial events, they were one of the first people to realize how to predict solar eclipses, follow the path of the sun through stars (what we call the ecliptic) And they could have created the first Zodiac.
While many of the constellations we now use are associated with Greek mythology, the ancient Greeks did not invent the shape of the constellations, but added their own stories to the constellations that already existed. Aratos, in 270 B.C. listed 42 constellations he knew that were already established. Ptolemy, in turn, listed 48 constellations in the 2nd century d. C. summing up earlier works, and Hipparchus (about 150 BC) was the first man to precisely trace the stars.
The Chinese independently developed their own constellations, but were not recognized by the Western world. However, they recorded their observations very accurately, and those records can still be used today to pinpoint the location of past supernovae, comets, and other celestial events.
The constellations of the southern sky did not add up until the Europeans started sailing around the world and the sailors found an unknown sky. Johann Bayer (1572-1625) was the next to increase the number of constellations considerably.
The constellations had no fixed limits. The ancient Greeks only considered the stars that created the constellation pattern to be part of it. The first printed tablets that appeared in the 16th century had no limits, as they were supposed to be a guide to the stars with the naked eye.
At the end of the 19th century everything began to be a little more complicated and it would logically be easier if everyone used the same constellations with the same limits. Therefore, in the 1920s, the newly created International Astronomical Union commissioned the French Eugene Delaporte to create a uniform sky for the use of astronomers.
The 88 constellations that we now use generically were presented by Eugene Delaporte in 1930. This is why the Zodiac of astrologers does not coincide with the modern sky. Astrologers assign exactly 30 degrees of the ecliptic to each constellation / representative sign. For an astronomer, the Zodiac has no other meaning than an interesting piece of history that helped ancient civilizations track the seasons, as the sun clearly travels through more than 12 "modern" constellations on their annual trip. Some constellations did not survive or fell from grace. Scorpio, for example, once had long claws that are now part of Libra. We have to remember this reminiscence the proper names of the stars, Zubenelgenubi la Garra del Sur and Zubeneschamali la Garra del Norte. The Pleiades were also once considered a constellation on their own, but they now reside within the limits of the constellation of Taurus.
The constellation of Carina, the Keel is located in the southern celestial hemisphere. It used to be part of a much larger constellation Argo Navis, but the International Astronomical Union divided it into four components: Carina, Vela, Puppis and Pyxis Argo Navis was 'drawn' by the Greek astronomer Ptolemy in the 2nd century. It was the French astronomer Nicolas Louis de Lacaille who divided it into the three smallest constellations, Carina, Puppis and Vela, in the 18th century. The three smallest constellations were added to the official list of modern constellations in the early 20th century, when the International Astronomical Union (IAU) defined the boundaries in the celestial sphere.
The constellation of La Dorada is found in the southern hemisphere. Its name means "el pez dorado" (Coryphaena hippurus) in Spanish. This constellation was created by the Dutch astronomer Petrus Plancius from observations by Dutch navigators Pieter Dirkszoon Keyser and Frederick de Houtman. It was first represented in Johann Bayer’s stellar atlas Uranometria in 1603.
Dorado contains most of the Great Magellanic Cloud, an irregular galaxy near the Milky Way. It’s constellation number 72, occupying an area of 179 square degrees. It is located in the first quadrant of the southern hemisphere and can be seen at latitudes between + 20 and -90 degrees.
Dorado has two stars with known planets and does not contain Messier objects. The brightest star in the constellation is Alpha Doradus. No meteor showers associated with the constellation.
The constellation of Aquarius is located in the southern hemisphere. Aquarius is located in the region of the sky that is sometimes known as the Sea, as it contains a series of 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 Beta Aquarii and a number of remarkable objects from the deep sky such as the globular clusters Messier 2 and Messier 72 or the asterism Messier 73.
Aquarius is the tenth largest constellation in the sky, occupying an area of 980 square degrees. It is located in the fourth quadrant of the southern hemisphere and can be seen at latitudes between + 65 and -90 degrees.
The constellation of Centaurus or the Centaur is located in the southern hemisphere. It is one of the largest constellations in the sky. It represents the centaur, the half-man half-horse creature of Greek mythology. The sources tend to differ on what centaur the constellation represents, but it is generally considered that it was Chiron, mentor of the Greek heroes Hercules, Peleus, Achilles, Theseus and Perseus. Centaur contains two of the ten brightest stars in the sky: Alpha Centauri and Beta Centauri. It is also home to Centaurus A, one of the brightest galaxies in the night sky, and the globular cluster Omega Centauri. It was one of the constellations catalogued by the Greek astronomer Ptolemy in the second century, but it was mentioned earlier in Greek texts by the astronomer Eudoxo and the poet Arato.
Centaurus is the ninth largest constellation in the sky, occupying an area of 1060 square degrees. It is located in the third quadrant of the Southern Hemisphere and can be seen at latitudes between + 25 and -90 degrees. It contains 11 stars with known planets and has no Messier object.

The constellation of Hercules is located in the northern sky. The constellation has a long history, dating back to the Sumerian era.
Hercules is the fifth largest constellation in the sky, but it has no first-magnitude stars. In mythology, the constellation of Hercules is usually associated with the penultimate work of Heracles, which involved killing the dragon Ladon, who guarded the Garden of the Hesperides. The dragon is represented by the constellation of Draco. The constellation of Hercules was first catalogued by the Greek astronomer Ptolemy in the 2nd century.
Notable objects from the deep sky in Hercules include the Great Globular Cluster (Messier 13), the globular cluster Messier 92, the planetary nebulae Abell 39 and NGC 6210, the Hercules Galaxy Cluster and the Abell 2199 galaxy cluster.

Its brightest stars form the Big Dipper asterism or The Chariot, one of the most recognizable shapes in the sky. It is a constellation well known in most cultures of the world and is associated with several myths. It was one of the constellations catalogued by the Greek astronomer Ptolemy in the 2nd century.
In Greek mythology, it is associated with Callisto, a nymph who was turned into a bear by the jealous wife of Zeus, Hera.
The Big Dipper contains a number of remarkable stars and famous deep-sky objects, including the Pinwheel Galaxy (M101), the Bode Galaxy, the Cigar Galaxy and the Owl Nebula.
The constellation of Ursa Minor is located in the northern sky. It is easy to recognize because it highlights the location of the celestial north pole, as it is home to Polaris, the North Star, which is at the end of the constellation. It is believed that the constellation was created by Thales of Miletus, the philosopher and astronomer who lived between 625 and 545 B.C. and known as one of the Seven Wise Men of Greece.
Phoenicians often used the Ursa Minor in navigation because, being so close to the North Pole, the constellation was an excellent guide for pointing north.
The Osa Menor is 56th (out of 88) in size, occupying an area of 256 square degrees. It is located in the third quadrant of the northern hemisphere and can be seen at latitudes between + 90 [ and -10 [ .

The constellation of Orion is one of the brightest and best known constellations in the night sky. It is located at the celestial equator. Orion has been known since ancient times. In Greek mythology it represents the mythical hunter Orion, who often appears depicted on star maps, either facing Taurus, chasing the Pleiade sisters, represented by the famous open cluster, or chasing the hare (constellation Lepus) with its two hunting dogs, represented by the nearby constellations Canis Major and Canis Minor.
The constellation of Orion contains two of the ten brightest stars in the sky: Rigel (Beta Orionis) and Betelgeuse (Alpha Orionis), several famous nebulae: the Orion Nebula (Messier 42), the Mairan Nebula (Messier 43) and the famous Horse Head.
