What celestial object is called a constellation. What are the names of the constellations and how some of them appeared

A beginner who begins to study the starry sky is first of all surprised by the names of the constellations. As a rule, in the arrangement of the stars, even a person with a rich imagination cannot see what the name of the constellation indicates. Ursa Major, for example (at least the main part of that constellation), looks more like a bucket, but randomly

groups of faint stars scattered in the neighborhood, called the constellations of the Giraffe and. Lynxes are not at all like a giraffe or a lynx. The variety of names is no less strange. In the sky, the constellations Bootes (or Shepherd) and Sextant, Hydra and Fly, Microscope and Lizard easily get along! What caused this set of names, completely chaotic at first glance?

The starry sky reflected in itself different eras and the creativity of different peoples. Modern generally recognized, so to speak, official, star charts with their 88 constellations have completed

centuries-old attempts to perpetuate objects in the sky that are far from always deserving of this. In the history of the constellations, there is a lot of arbitrary, and sometimes just ridiculous. Often not so

just to find out for what reasons a particular constellation appeared in the sky, and even to this day, in some cases, it remains controversial what the names of individual constellations mean,

Even the final, final list of 88 constellations was compiled not so much according to some logical principle, as from the desire to preserve, finally, unchanged, the prevailing

by this time a picture of the sky. Ursa Major, Orion, Taurus, Big Dog, Lesser

Dog, Bootes, Ursa Minor, Dragon, Hercules, Aquarius, Capricorn, Sagittarius, Arrow, Dolphin, Hare, Eri dan, Whale, Southern Fish, Small Horse, Centaurus, Wolf, Hydra, Bowl, Raven, Libra,

Hair of Veronica, Southern Cross, Northern Crown, Ophiuchus, Scorpio ,. Virgo, Gemini, Cancer, Leo, Charioteer, Cepheus, Cassiopeia, Andromeda, Pegasus, Aries, Triangle, Pisces, Perseus,

Lyra, Swan, Eagle. Most of these 46 constellations are of mythological origin - they depict characters from ancient Greek myths and legends. Another group of constellations was first mentioned by the astronomer Jean Bayer, who published in 1603 a magnificently designed atlas of the starry sky. It includes Peacock, Toucan, Crane, Phoenix, Flying Fish, Southern Hydra, Goldfish, Chameleon, Bird of Paradise, Southern Triangle, Indian.

By the end of the 17th century. in the list of constellations compiled by the famous Gdansk astronomer Hevelius, you can find a number of new constellations that have appeared over the course of a century. These are Giraffe, Fly, Unicorn, Dove, Hounds, Dogs, Chanterelle, Lizard, Sextant, Little Lion, Lynx, Shield, South Crown. In 1752, the famous explorer of the southern starry sky, the French astronomer Lacaille, added 14 more constellations to the list. Here they are: Sculptor, Furnace, Clock, Grid, Cutter,

Painter, Altar, Compass, Pump, Octant, Compass, Telescope, Microscope, Table Mountain. All these constellations are located in the southern hemisphere of the starry sky. We have left

add only five constellations to the list. Three of them - Keel, Korma and Sails - in ancient times constituted the main part of the constellation of the Ship - the very mythical ship on

which, according to ancient Greek legends, the heroes-Argonauts traveled to Colchis. The fourth constellation, Serpent, is remarkable in that it underestimates two

separate areas of the sky. You might even think that there are two constellations of the Serpent in the sky close to each other. In fact, this is one constellation, separated by the constellation Ophiuchus. Ancient star charts depict a man holding a snake.

The last, 88th constellation. The triangle is located in the southern starry sky, and its origin is as arbitrary as that of the Southern Triangle. From this brief listing of the constellations, we can conclude that the names of the oldest of them owe their origin to various ancient myths.

Even ancient people united the stars in our sky into constellations. In ancient times, when the true nature of celestial bodies was unknown, the inhabitants assigned the outlines of any animals or objects to the characteristic "patterns" of stars. Later, the stars and constellations were overgrown with legends and myths.

Star maps

Today, there are 88 constellations. Many of them are quite remarkable (Orion, Cassiopeia, Dipper) and contain many interesting objects that are available not only to professional astronomers and amateurs, but also to ordinary people. On the pages of this section, we will tell you about the most interesting objects in the constellations, their location, we will give a lot of photos and entertaining video recordings.

Thanks to the observations of astronomers, it turned out that the arrangement of the stars gradually changes over time. Accurate measurements of these changes take many hundreds and thousands of years. The night sky creates the appearance of an innumerable number of celestial bodies, randomly located in an arrangement to each other, which often draw constellations in the sky. More than 3 thousand stars are visible in the visible part of the sky, and 6,000 in the entire sky.

Visible location


Constellation Cygnus from Johann Bayer's atlas "Uranometria" 1603

The location of dim stars can be determined by finding the bright ones, and thus finding the required constellation. Since ancient times, in order to make it easier to find constellations, bright stars have been combined into groups. These constellations received the names of animals (Scorpio, Ursa Major, etc.), were named after the heroes of Greek myths (Perseus, Andromeda, etc.), or by simple names of objects (Libra, Arrow, Northern Crown, etc.). From the 18th century onwards, some of the brightest stars in each constellation began to be called letters of the Greek alphabet. In addition, about 130 brightly glowing stars were called by their names. After some time, astronomers designated them with numbers, which are used today for stars of weak brightness. Since 1922, some large constellations were divided into small ones, and instead of constellation groups, they began to be considered parts of the starry sky. At the moment, there are 88 separate areas in the sky, called constellations.

Observation

For several hours of observing the night sky, one can see how the celestial sphere, which includes the luminaries as a whole, smoothly rotates around an invisible axis. This movement was called diurnal. The luminaries move from left to right.

The moon and the sun, as well as the stars, rise in the east, in the southern part they rise to the maximum height, set on the horizon of the western side. Observing the rising and setting of these luminaries, it is found that, unlike the stars, corresponding to different days of the year, they rise in the east at different points and set in the west at different points. In December, the Sun rises in the southeast and sets in the southwest. Over time, the points of west and rise move towards the horizon of the north side. Accordingly, the Sun rises at noon higher above the horizon line every day, the length of the day becomes longer, and the length of the night decreases.


Movement of celestial objects in constellations

According to the observations made, it can be seen that the Moon is not all the time in the same constellation, but moves from one to another, moving from west to east at 13 degrees per day. In the sky, the moon makes a full circle in 27.32 days, passing through 12 constellations. The sun makes a similar path as the moon, however, the speed of the sun is 1 degree per day and the entire path takes a year.

Zodiac constellations

The names of the constellations along which the Sun and the Moon pass were named after the zodiacs (Pisces, Capricorn, Virgo, Libra, Sagittarius, Scorpio, Leo, Aquarius, Taurus, Gemini, Cancer, Aries). The first three constellations of the Sun passes in the spring, the next three in the summer, the next in the same way. Only six months later, those constellations in which the sun is now become visible.

Popular science film "Secrets of the Universe - Constellations"

Looking at the night sky as a child, we try to understand what constellations are. We are interested in the names formed by the stars of the figure, but not in the definition of the very concept of "constellation". Meanwhile, even as adults, we do not always understand what actually lies behind this familiar word.

Projection

A spaceship flying into space will never reach any of the existing celestial drawings. The reason for this is that the stars lying, as it seems to us, on the same plane, are actually remote from each other, sometimes at great distances. The constellation is a projection of a separate fragment of the celestial sphere with all space objects located on it.

A bit of history

The ideas about what constellations are, were different in different centuries. Today, 88 heavenly drawings are distinguished, but this was not always the case. Ancient constellations and their names were ordered and described by Ptolemy in his famous treatise "Almagest". His list included 48 celestial drawings. All of them, with the exception of one, have retained their names to this day. The large constellation Argo (the ship of the Argonauts) was subsequently divided into three smaller ones: Carina, Korma and Parus. Initially, the heavenly drawings, which are called ancient today, were described as early as four centuries before Ptolemy, in 245 BC. NS. This was also done by the Greek poet Arat.

The need to supplement the existing list came at the time of the Great Discoveries: the stars marked on the maps did not help to navigate the vastness of the ocean. In the late 16th century, travelers Frederic de Houtman and Peter Keizer combined the stars into 12 more celestial drawings. Among them were Chameleon, Phoenix, Southern Hydra. A dozen constellations can be found today on the map of the Southern Hemisphere of the starry sky.

In 1613, Peter Planzius painted several new celestial drawings on his globe, and in 1624, thanks to the German astronomer, physician and mathematician Jacob Bartsch, they began to be used throughout the scientific world. Today, only two of them have survived - the Giraffe and the Unicorn.

Final formation

The list of constellations was not completed on this. Jan Hevelius in the 17th century identified seven more star drawings (Sextant, Little Lion, Lizard, Shield, Lynx, Fox, Hounds Dogs). In the next, 18th century, Nicolas Louis de Lacaille also contributed. He depicted 17 constellations that completed the formation of the list.

However, the history of the names of the constellations did not end there. The ancient celestial drawings have been renamed several times, replacing the Greek gods and heroes with Christian saints. Sometimes reigning persons and military leaders wanted to feel the glory of the Olympians. However, all these attempts have been unsuccessful.

Borders

By the end of the 18th century, the modern understanding of constellations was finally established. The names of the celestial images are also more or less settled. It only remained to determine the boundaries.

Today, a constellation is understood not only as certain luminaries that create a recognizable silhouette. It includes the entire "territory" near these stars. The constellations are separated by boundaries approved in 1935 after a long collaboration of several famous astronomers.

Continuous movement

The constellations were fixed in one way or another on the map, but if you watch the stars all night, it is easy to see that the celestial drawings are constantly moving. Some move around a single center, others describe an arc and disappear behind the horizon. This change in position was called diurnal rotation. If the observer is in and faces south, then the stars for him will move clockwise, rising in the east and disappearing in the west. The constellations rise as high as possible above the southern part of the horizon. If you observe the movement of the stars, facing north, the picture changes somewhat. Some of the luminaries do not go beyond the horizon, but describe a circle in the sky. Its center is the so-called peace. The North Star is located nearby.

At the same time, the same bright point always rises and sets in a strictly defined place, in contrast to the Sun and the Moon, the places of rising and setting of which are shifted every day. and the daylight "travels" from one constellation to another. Thus, they "visit" the twelve heavenly drawings. The sun travels its way throughout the year, and the moon - in over 27 days. Hospitable "houses" that receive the daylight once every twelve months make up the Zodiacal circle.

The pillars of astrology

Perhaps everyone knows what constellations of the signs of the zodiac exist. It is interesting that the heavenly picture in which the Sun is located in a particular month is always hidden from the observer and appears only six months later.

The signs of the zodiac have been known to mankind for a very long time. Some of their names sounded back in Mesopotamia, the cradle of one of the first civilizations. The word "zodiac" itself is of Greek origin: zodiakos means "animal" in translation. The twelve constellations got this name due to the fact that most of them look like animals.

The zodiacal circle covers the orbit not only of the Moon, but also of all the planets of the solar system. It is located at an angle to the celestial equator and intersects with it at two points corresponding to the spring and autumn equinox.

Poles of the world

You can answer the question of what constellations are in different ways. Astronomers have developed a special coordinate system to determine them. The North Pole of the world has already been mentioned above. It is easy to assume that there is a South one, which is indicated by And where the poles are, there is the equator. In a coordinate system built on the sky, there is declination (latitude, distance to the equator) and right ascension (longitude).

The Equator passes through certain constellations: Orion, Pisces, Whale, Taurus, Eridanus, Sextant, Eagle, Unicorn, Hydra, Ophiuchus, Dog Minor, Leo, Aquarius, Serpent. A feature of these celestial drawings is the availability for observation almost anywhere in the world. This is possible precisely because of the location of the constellations.

North

There are several more classifications that complement our understanding of what a constellation is. All celestial drawings are divided into belonging to the Northern or Southern hemisphere of the starry sky.

The list of constellations of the Northern Hemisphere includes images of three signs of the zodiac: Gemini, Aries and Cancer. This also includes the heavenly drawings of animals: Ursa Major and Ursa Minor, Dolphin, Dragon, Giraffe, Hounds, Swan, Chanterelle, Little Horse and Little Lion, Lynx and Lizard. Among the constellations of the Northern Hemisphere, there are those named after the characters of ancient mythology: Hair of Veronica, Andromeda, Cepheus, Perseus, Pegasus, Hercules, Cassiopeia, Bootes, and designating objects: Lyra, Sextant, Arrow, Triangle.

On the other side of the earth

Now let's see what constellations are visible to an observer in the Southern Hemisphere. Most of the celestial drawings here are named after inanimate objects and their parts: Altar, Compass, Poop, Keel, Microscope, Bowl, Square, Octant, Telescope, Pump, Cutter, Sails, Furnace, Grid, Compass, Clock, Shield, South Crown, Southern Cross and Southern Triangle. Of the signs of the zodiac, the southern constellations include Capricorn, Scorpio and Sagittarius. Of the mythical characters, only Phoenix and Cepheus are located here, but there are art workers (Sculptor and Painter) and a representative of one of the peoples (Indian), as well as the embodiment of a miracle of nature (Table Mountain). There are many animals here: Big Dog, Raven, Dove, Wolf, Flying, Golden and Southern Fish, Crane, Hare, Bird of Paradise, Peacock, Fly, Toucan, Chameleon, Southern Hydra.

In winter and summer

This is not the only answer to the question of what a constellation is. Another classification principle is the time of year at which the celestial pattern is best observed. Indeed, in summer, winter, spring and autumn, different images dominate overhead.

In June, July and August, Lyra and Eagle adorn the sky, the brightest points of which form the Summer Triangle asterism. Bootes, Northern Crown, Compasses, Hercules and several other celestial drawings are also available for observation at this time of year.

In winter, the space above your head is no less beautiful than in summer. In the evening, the constellation Orion appears above the horizon. It is easy to find by three bright points lined up in a row. This is an asterism Below and slightly to the right of it is Rigel, the most noticeable star in this celestial drawing. If the Belt continues to the left and down, then the straight line will soon run into Sirius, Alpha Canis Major and the brightest star in the entire sky. Both the Great and Lesser Dogs also belong to the winter constellations. At the other end, the straight line passing through Orion's Belt abuts against Aldebaran, which belongs to Taurus.

In autumn and spring

The end of summer is accompanied by a change in the main constellations of the sky. Pisces, Cassiopeia and Andromeda are now best seen. Although their brightness is inferior to Orion and Swan, they decorate the sky just as well and are also worthy of attention.

In spring, the space above your head is illuminated by the stars of the Big Dipper, Leo, Virgo, Bootes. Of course, they are noticeable in other periods, but it is spring that is the time of their "reign" in heaven.

The main constellations and names of stars have been known to us since antiquity. Since then, their list has been supplemented and modified. The list of 88 celestial drawings is an exhaustive answer to the question of what constellations are. Their names give an idea of ​​the time of the appearance of these stellar drawings on the maps of the starry sky. So, almost all mythical characters shone in the era of Ancient Greece and Rome. Most of the animals familiar to modern man, as well as the silhouettes of artists and various devices, are the result of a rethinking of the star map in the 17-18 centuries. The search for constellations facilitates their relationship with the celestial equator and the poles of the world.

Constellations.

A constellation in astronomy is simply a region of the sky within some set boundaries ...
Each cultured people had their own constellations, which were very different both in number and in names or position on the celestial sphere. We will not go into details, since more than one book can be written on this topic ... In general, the situation demanded order, and it was put in place. The final list of 88 modern constellations and their boundaries was approved at the meeting of the International Astronomical Congress in 1922.
The table shows the Russian and Latin names of the constellations, their generally accepted three-letter abbreviations, and in the last column - the spelling of the constellation in the genitive case. Knowing this is important, since it is correct to say not only " Alpha Andromeda" or " Beta Gemini", but also Alpha andromedae and Beta Geminorum...

Humanity has always looked to the sky. The stars have long been sailors' guides, and they remain so today. A constellation is considered to be a group of celestial bodies, which are united by one name. However, they can be at different distances from each other. Moreover, in ancient times the name of the constellations often depended on the outlines taken by celestial bodies. More details about this will be discussed in this article.

General information

There are eighty-eight registered constellations in total. Of these, only forty-seven have been known to mankind since ancient times. Thanks to the astronomer Claudius Ptolemy, who systematized the known constellations of the starry sky in the treatise "Almagest". The rest appeared at a time when a person began to intensively study the world around him, travel more and write down his knowledge. So, other groups of objects appeared in the sky.

The constellations in the sky and their names (photos of some of them will be presented in the article) are quite diverse. Many have several names, as well as ancient legends of origin. For example, there is a rather interesting legend about the appearance of the Ursa Major and Ursa Minor in the firmament. In those days when the gods ruled the world, the most powerful of them was Zeus. And he fell in love with the beautiful nymph Callisto, and he took her as his wife. In order to protect her from Hera, jealous and dangerous in her anger, Zeus took his beloved to heaven, turning her into a bear. So it turned out the constellation Ursa Major. Callisto's dog became Ursa Minor.

Zodiacal constellations of the solar system: names

The most famous constellations for humanity today are the zodiacal. For a long time, those who meet on the path of our Sun during its annual journey (ecliptic) have been considered as such. This is a fairly wide strip of heavenly space, divided into twelve segments.

Constellation name:

  1. Aries;
  2. Taurus;
  3. Twins;
  4. Virgo;
  5. Capricorn;
  6. Aquarius;
  7. Fishes;
  8. Scales;
  9. Scorpion;
  10. Sagittarius;
  11. Ophiuchus.

As you can see, unlike the signs of the zodiac, there is another constellation here - the thirteenth. This happened because the shape of the celestial bodies changes over time. The signs of the zodiac were formed quite a long time ago, when the sky map was slightly different. To date, the position of the stars has undergone some changes. So, on the path of the Sun, another constellation appeared - Ophiuchus. In its order, it stands just after the Scorpio.

The spring equinox is considered to be the starting point of the solar journey. At this moment, our star passes along the celestial equator, and the day becomes equal to the night (there is also an opposite point of the same - autumn).

Constellations Ursa Major and Ursa Minor

One of the most famous constellations of our firmament is the Ursa Major and the accompanying Little Dipper. But why did it happen that not the most pretentious constellation became so important? The fact is that the Polar Star is present in the Ursa Minor's cluster of celestial bodies, which was a guiding star for many generations of sailors, and it remains so today.

This is due to its practical immobility. It is located near the North Pole, and the rest of the stars in the sky revolve around it. This feature was noticed by our ancestors, which was reflected in its name among different peoples (Golden stake, Heavenly stake, North Star, etc.).

Of course, there are other main objects around this constellation of the starry sky, the names of which are listed below:

  • Cohab (Beta);
  • Ferkhad (Gamma);
  • Delta;
  • Epsilon;
  • Zeta;

If we talk about the Big Dipper, then it more clearly resembles a bucket in its shape than its small counterpart. According to estimates, only with the naked eye in the constellation there are about one hundred and twenty-five stars. However, there are seven main ones:

  • Dubhe (Alpha);
  • Merak (Beta);
  • Fekda (Gamma);
  • Megrets (Delta);
  • Aliot (Epsilon);
  • Mitsar (Zeta);
  • Benetnash (This).

Ursa Major has nebulae and galaxies, like numerous other stellar constellations. Their names are presented below:

  • Spiral galaxy M81;
  • The Owl Nebula;
  • Spiral Galaxy "Pinwheel;
  • Barred spiral galaxy M109.

Most amazing stars

Of course, our sky has quite remarkable constellations (photos and names of some are presented in the article). However, besides them, there are other amazing stars. For example, in the constellation Canis Major, which is considered ancient, since our ancestors knew about it, there is the star Sirius. Many legends and myths are associated with it. In Ancient Egypt, the movement of this star was very carefully monitored, there are even assumptions by some scientists that the African pyramids with their edge are aimed precisely at it.

Today Sirius is one of the stars closest to Earth. Its characteristics are twice as high as solar. It is believed that if Sirius were in the place of our star, then life on the planet in the form it is now would hardly be possible. With such intense heat, all the oceans from the surface would have boiled away.

A rather interesting star that can be seen in the sky of Antarctica is Alpha Centauri. This is the closest similar star to the Earth. By its structure, this body contains three stars, two of which may well have terrestrial planets. The third, Proxima Centauri, according to all calculations, cannot have such, since it is rather small and cold.

Large and small constellations

It should be noted that today there are fixed large and small constellations. Photos and their names will be presented below. One of the largest can be safely called Hydra. This constellation covers an area of ​​the sky of 1302.84 square degrees. Obviously, this is why it received such a name, all in appearance it resembles a thin and long strip that occupies a quarter of the stellar space. The main place where Hydra is located is south of the line of the celestial equator.

In terms of its stellar composition, Hydra is rather dim. It includes only two worthy objects that stand out significantly in the sky - Alphard and Gamma Hydra. An open cluster called M48 can also be noted. The second largest constellation belongs to Virgo, which is slightly smaller in size. Therefore, the representative of the space community described below is truly small.

So, the smallest constellation in the sky is the Southern Cross, which is located in the Southern Hemisphere. It is considered an analogue of the Big Dipper in the North. Its area is sixty-eight square degrees. According to ancient astronomical chronicles, it used to be part of Centauri, and only in 1589 it was isolated separately. In the Southern Cross, about thirty stars are visible even with the naked eye.

In addition, there is a dark nebula in the constellation called the Coal Sack. It is interesting in that star formation processes can take place in it. Another unusual object is the open cluster of celestial bodies - NGC 4755.

Seasonal constellations

It should also be noted that the name of the constellations in the sky changes from season to season. For example, in summer the following are clearly visible:

  • Lyre;
  • Eagle;
  • Hercules;
  • Snake;
  • Chanterelle;
  • Dolphin, etc.

Other constellations are characteristic of the winter sky. For example:

  • Big Dog;
  • Small Dog;
  • Auriga;
  • Unicorn;
  • Eridan, etc.

The autumn sky is the following constellations:

  • Pegasus;
  • Andromeda;
  • Perseus;
  • Triangle;
  • Keith et al.

And the following constellations open the spring sky:

  • Little Lion;
  • Crow;
  • Bowl;
  • Hounds Dogs and others.

Constellations of the northern hemisphere

Each hemisphere of the Earth has its own celestial objects. The names of the stars and the constellations they enter are quite different. So, let's consider which of them are typical for the northern hemisphere:

  • Andromeda;
  • Auriga;
  • Twins;
  • Veronica's hair;
  • Giraffe;
  • Cassiopeia;
  • Northern Crown and others.

Constellations of the southern hemisphere

The names of the stars and the constellations they enter are also different for the southern hemisphere. Let's take a look at some of them:

  • Crow;
  • Altar;
  • Peacock;
  • Octant;
  • Bowl;
  • Phoenix;
  • Centaurus;
  • Chameleon and others.

Indeed, all the constellations in the sky and their names (photo below) are quite unique. Many have their own special history, beautiful legend or unusual objects. The latter include the constellations Doradus and Toucan. The first contains the Large Magellanic Cloud, and the second contains the Small. These two objects are truly amazing.

The Big Cloud looks very much like a Segner wheel, while the Small Cloud looks like a punching bag. They are quite large in terms of their area in the sky, and observers note their similarity to the Milky Way (although they are much smaller in real size). They seem to be a part of it, which separated in the process. However, in their composition, they are very similar to our galaxy, moreover, the Clouds are the closest systems of stars to us.

A surprising factor is that our galaxy and the Clouds can revolve around the same center of gravity, which forms a triple star system. True, each of this trinity has its own star clusters, nebulae and other space objects.

Conclusion

So, as you can see, the name of the constellations is quite diverse and unique. Each of them has its own interesting objects, stars. Of course, today we do not know even half of all the secrets of the cosmic order, but there is hope for the future. The human mind is quite inquisitive, and if we do not perish in a global catastrophe, then there is the possibility of conquering and conquering space, building new and more powerful devices and ships to gain knowledge. In this case, we will not only know the name of the constellations, but also comprehend much more.
