Winter constellation

What constellations are there in winter? Imperial constellation

One of the northern constellations. Center position: 6: 00 right ascension, 42 right declination. The area is about 658 square degrees. Located between Perseus, Taurus, Gemini and other constellations, half of them are immersed in the Milky Way. The visual magnitude of 102 stars in the constellation is greater than 6, and the brightness of 10 stars is greater than 4.

Carving seat

Carver is a constellation designated by French astronomer Llakaj in 1752 to fill the gap in the southern hemisphere. From 175 1 to 1752, when Llakaj passed the Cape of Good Hope, he designated this constellation. At first, it was named "the sculptor's file", and later it was renamed "the sculptor's tool". Because the sculpture pedestal was a southern hemisphere constellation established only in17th century, there was no myth related to it before17th century.

Lubao

The leopard is located in the northern part of the celestial sphere. It is surrounded by bears, fairy kings, dragons, bears, Tmall, Yufu and Perseus. It is a big "tall and thin" constellation, but it is darker than 4 stars. Generally, residents in the area south of 7 degrees south latitude can't see this constellation.

Cancer constellation

Cancer is located to the west of Leo and to the north of snakehead. It is the darkest of the twelve constellations. The brightest star in the constellation is only 93.8m, and you can't see the shape of a crab at all. This may be because Hercules had already hit it with a stick. That's right, it still clings to the long snake and goes along with it!

Sirius

One of the southern constellations. The center position is 6: 40 right ascension and -22 declination. The area is about 380 square degrees. Located in the southeast of Orion, between Scorpio and tail constellation. There are 122 stars in the constellation whose visual magnitude is greater than 6, of which 18 stars are greater than 4.

Canine constellation

A constellation in the dog constellation. Located in the eastern part of Orion, between Gemini and Unicorn, on the edge of the Milky Way. There are 1 yellow bright stars in this constellation, named "Nanhesan". Nanhesan, Betelgeuse and Sirius in the northeast corner of Orion form an equilateral triangle, which is called the "winter triangle" and is very eye-catching in winter nights.

Ship base

Ptolemy said that the tailstock, the vela and the carina are the same constellation (excluding the compass), which is called Argonavis. /kloc-In the 8th century, astronomers thought that the Southern Constellation occupied too much space, so they took it apart. The ship to the south is Argo. In the story, Jason took fifty people aboard Argo to Korcz in the Black Sea to find golden fleece.

swordfish

Swordfish is located in the southwest of Carina, which contains the famous large magellanic cloud. It was discovered by Portuguese navigator Magellan when he sailed around the world to South America in 1520.

In fact, this "Large Magellanic Cloud" is an extragalactic galaxy and a companion galaxy of our Milky Way, with a diameter of 50,000 light years and a distance of160,000 light years.

Bojiangzuo

One of the southern constellations. The constellation with the largest span between north and south. Starting near the southern tip of Orion, it winds between Taurus, Pisces and Scorpio until the southern sky is next to Aquarius. It is one of the main southern constellations in the northern hemisphere on winter nights. The center position is: 3: 50 right ascension, declination-18. The area is about 1 138 square degrees. Between Pisces and Orion, it extends southward from the equator to about-60 declination. Most of the stars in the whole constellation are dark, and only one head and one tail are prominent. The bright star at the southernmost tip of the Bojiang constellation is Water Commission I, which can only be seen in the south of China.

Gemini

Extending the connecting line between Orion's beta star and alpha star to the northeast, we can meet two bright stars which are not far apart, among which the brighter one is Gemini's beta star with brightness of 1. 14, etc. The dimmer star is Alpha Gemini with a brightness of 1.97. A series of stars τ, ε, μ starting from α star are almost parallel to another series of stars τ, ζ, γ starting from β star, and are imagined as two friendly brothers ―― Caster and Polox Polokus.

The main constellation in the winter sky is Alpha Auriga (known as Capella in Chinese), which is a famous bright star in the northern sky with an apparent magnitude of 0.08 and a distance of 42.20 light years. Capella is mbth of Capella, which means "Little Goat". The three dark stars near Capella are its three "lambs". The closest star to Capella is ε auriga (middle named 1), which is an eclipse star with a brightness ranging from 3. 1 to 3.8 and a period of 9900 days. ζ auriga, the farthest from Capella in Lamb, is also an eclipse star, with a brightness of 4.9-5.5 and a dimming period of 972 days. South of Lamb, Auriga ω is a binary star (5.0, 8.0, etc. ) is 5 ".8. Auriga θ, the vertex on the east side of the Pentagon, is also a binary star (2.7, 7.5, 3 ".0). There are three open clusters in Auriga. M36 is a beautiful and regular open cluster with an angular diameter of 17' and a distance of 4 100 light years. The open cluster M37 has an apparent magnitude of 6.2 and an angular diameter of 25', which is more beautiful than M36. The bright star near the center of the cluster is red, with a distance of 3900 light years. The open cluster M38 has a magnitude of 7.4, an angular diameter of 18' and a distance of 3900 light years. It looks like a crucible with many stars. The twelve constellations in the winter night sky are Aries, Taurus and Gemini. There are not many bright stars in Aries, which are not obvious. Several bright stars form a broken line. Among them, Aries ε is a binary star (5.2, 5.5, etc., 1 ".5). The stars of Taurus are arranged in horizontally placed forks, one of which extends to the pentagon of Auriga. The star at the south vertex of the Pentagon is called "Five Cars and Five". In fact, it is the second bright star of Taurus, Taurus β. Taurus has many famous celestial bodies. Alpha Taurus (middle name: Bisuwu) is a standard 1 star, which belongs to K-type star, and its surface temperature is about 4000K, so its color is red. It is a binary star, the main star is 1.0, the companion star is 1 1, and the angular distance between the two stars is 3 1.4 ",which is still increasing. It is about 65 light-years away from us, with a radius 47 times larger than that of the sun and a volume 65,438+million times larger than that of the sun. Taurus λ, located in the middle of Taurus fork handle, is a large variable star with a light variation range of 3.3 ~ 4.2 and a light variation period of 3.95 days. From Taurus λ to the north, you can see a dense cluster of small stars, which is the famous M45 open cluster. It is the most obvious open cluster in the northern sky. Because it is the Pleiades in the Twenty-eight Hostages, it is called Pleiades in China and Seven Sisters Cluster abroad. The naked eye can see that there are six bright stars, and there are actually hundreds of members of this open cluster. In ancient times, the Pleiades star cluster was attached great importance at home and abroad, and the four seasons were judged according to its position in the sky. Through telescope observation, a gas nebula (NGC 1435) can be seen in the Pleiades cluster. There is also a famous gas nebula M 1 near the zeta end of Taurus, which is another branch of Taurus bifurcation. It is a planetary nebula, which is also called the crab nebula because it looks like a crab. The crab nebula was formed after the supernova explosion in 1054, with an angular diameter of 420″× 288″ (the actual size is 8. 8× 12.8 light years). This nebula emits visible light and radio waves, as well as X-rays. It is also a source of infrared radiation and gamma rays. There is a star in the center of the Crab Nebula, which has been found to be a pulsar, both a radio pulsar and an optical pulsar. Gemini stars are arranged in a rectangle. The bright star Gemini Alpha (named Beihe II) and Gemini Beta (named Beihe III) are not far apart, and the brightness is almost equal. Beihe III is slightly brighter than Beihe II, and we can find Gemini according to them. Beihe II is a binary star, and the angular distance between the two sub-stars (2.0, 2.9, etc. ) It's getting closer. It's not easy to tell with a small telescope. Through the method of spectral analysis, it can be known that each sub-star of Beihe II is a split binary star, so Beihe II is a tetrad star. Gemini η is a binary star and a semi-regular variable star. Gemini μ, λ, σ and κ are also binary stars. Zeta Gemini is a Cepheid variable star. These stars are all above level 4 and relatively bright. M35 is an open cluster of magnitude 5.3 near the star η of Gemini, which is located in the northwest corner of Gemini rectangle and can be seen by naked eyes. Very beautiful. The most striking thing in the winter sky is Orion. Four bright stars are arranged in a quadrangle, and three stars are neatly arranged in the center of the quadrangle, which is called "Samsung" by the people. There are three almost connected stars under Samsung, and the middle is >>.

What constellations are there in the winter night sky?

Southeast of Orion is Canis major. Sirius Canis the brightest star in the whole day and the most famous binary star. Its companion star is the first star to be identified as a white dwarf.

orion

Orion, the most striking star in the winter sky, is high in the southeast. Orion is a constellation with the brightest stars. There are three bright stars in the middle, such as Hunter Belt. Below Samsung, there are Horsehead Nebula and Orion Nebula. We can see the Orion nebula with the naked eye.

Taurus constellation

Taurus is northwest of Orion. The Pleiades cluster on its back is an excellent open cluster, commonly known as Seven Sisters. In addition, Taurus also has the famous Crab Nebula.

The story of Orion

Themis, the goddess of the moon, fell in love with Orrin, Poseidon's son. They often went out hunting together. Thanks to the careful design of Apollo, Artemis' brother, O 'Ryan finally died under Artemis' arrow. Themis was in great pain and asked Zeus to lift Olin to the sky, making him the most dazzling Orion in the sky.

The story of Ursa Major and Ursa Minor.

In Greek mythology, Zeus was described as a god who showed mercy everywhere.

When Zeus' wife Sheila learned about the affair between Zeus and Harriet, she was furious and turned her into a big bear after her son was born. Scarlett, who became a bear, wandered alone in the forest for more than ten years. One day, under Sheila's special arrangement, she met her son. At that time, he had become a teenager, but the teenager didn't know that the bear in front of him was his biological mother, and he wanted to shoot the bear. Zeus was shocked when he saw this, and immediately set off a tornado on the ground to rescue Scarlett Bear and lift her to the sky to become the "constellation Ursa Major". Later, his son was also lifted to the sky and became a "bear".

Sheila was angry that her rival in love had won such an honor. Persuade Poseidon to forbid Ursa Major and Ursa Minor from landing in the sea. Therefore, in the constellation, they can never land below the ground level.

What constellations can you see at night in winter? What are they like? The first bright star "Sirius" is a winter constellation, which is usually invisible in summer nights, and can only be seen in early summer (May and early June). The second and third bright stars are in the Antarctic region, which are generally not seen in the northern hemisphere, so the fourth bright star, arcturus, is the brightest at night this season.

What obvious constellations can you see under the night sky in Beijing in winter? What are their characteristics? Six main constellations in the winter sky:

Orion (seven bright and orderly stars, Orion nebula);

Taurus (Pleiades, the famous crab nebula);

Auriga (a prominent pentagon);

Gemini (neat rectangle);

Canis major (Nanhesan is very bright);

Canis Canis (Sirius has the highest brightness in the whole day, and another arrow shoots Sirius, the nine planets in the northwest);

The main stars of these six constellations form a striking hexagon, which is called the Winter Diamond. If you don't know these six constellations, I'm afraid no one will believe you if you say you know astronomy, hehe.

Second-class constellation:

Aries (both Lousu II and Lousu III are quite bright, the constellation at the turn of autumn and winter)

Sky map (the brightness is not bad, but the Chinese names are easy to remember, toilets and screens, we ancient people can lift to the sky)

Sagittarius (four third-class stars, arranged neatly)

Tail (more bright stars, Beijing can be lower)

Bojiang constellation (although the main body is in autumn, the Yujing in Heyuan originated from Orion)

Dark constellation:

Cancer is between Leo and Gemini, and the most obvious sign is not Liu Su's increase 10(3.8, etc. ), but the ghost cluster, that is, the pioneer, how dark this constellation is)

Unicorn (if Betelgeuse and Orion's belts are not arranged neatly, I can only say that there is nothing between the big dog and the puppy)

Deer and leopards (the empty sky north of Auriga)

The latitude of Beijing is almost these constellations. The starry sky in winter is the most prominent among the four seasons, but it is hard to say without pictures. Finally, attach a simulation map of Stellarium (the starry sky in winter is in the east half of the map). If you have time, you might as well download and play, which is very useful.

PS: Thanks to Hu Daying's friends for correcting me. Please pay attention to your answer in the future.

What constellations are there in the winter sky in the northern hemisphere? It's different at the same latitude.

The constellations visible throughout the year in the middle and high latitudes of the northern hemisphere are:

Ursa major, Ursa minor, and Empress Fairy.

Relatively speaking: Beichi

The brighter constellations between 60 degrees north latitude and the north celestial pole are Ursa major, Ursa minor and Cassiopeia, while Tianlong

The brightness of Cepheus is 2.5 ~ 6 times darker than the above three constellations, and observers can observe it with naked eyes.

Always look at the constellation where the bright star is, so it is difficult to observe Draco and Cepheus.

Besides Ursa major, Ursa minor and Empress Fairy, there is another constellation that should be Draco or Cepheus.
