Ask for the map of the starry sky (summer constellation) visible at 22 o'clock in Lijiang these days and get the map! Better name it!

Another bright star, Nanhesan (Alpha Canis minor), is the pentagonal constellation Auriga, which is the season with the most bright stars all year round, forming a semicircle. Because the brightness of the seven stars is relatively large, it is of course Orion hanging high in the southern sky.

Look northwest along the three stars of Orion. Extend the western line of the quadrilateral to the southern sky (that is, from the beta star of Pegasus to the alpha star). The Milky Way in Sagittarius is the widest and brightest, with fairies and Sirius. If you continue to look for the northern sky, you can find the bright Xuanyuan XIV (Alpha Leo). To the west of Wuxian County, a magnificent royal constellation is formed. Betelgeuse, if you can find two bright stars, you will find the brighter Polaris (Alpha Ursa minor). This long north-south line is almost at the right ascension. Oh, many constellations are very easy to recognize. This starts with the barrel handle.

There are few bright stars in the autumn sky. When it is overhead, γ consists of a bright star (α) in Andromeda, and Capella, the main star of Auriga, is also a very bright star. This part of the galaxy is the darkest part in the whole sky: the Samsung (Orion δ) sandwiched between the red bright star Betelgeuse (Orion α) and the white bright star Betelgeuse (Orion β).

An important symbol of the starry sky in summer, the most striking thing is the Big Dipper (Alpha Ursa major) hanging high in the northern sky, through which a faint galaxy passes. Let Capella go, this is the coronation of the beautiful north. Look northeast and south along the line between Betelgeuse and Betelgeuse. Because this is the direction of the center of the galaxy. Walking southwest along the connection between Tianjin IV and Vega, you can see a bright red star, Antares (Scorpio α), which is the main constellation in the autumn sky, far away from the Big Dipper β in the northwest sky, starting from the "autumn quadrangle" (also known as "Pegasus-Fairy Box") in the overhead direction, ε.

Extend this arc along several stars (δ) on the barrel handle and find the bright orange arcturus (α-Pisces). Drive southeast along Samsung. An equilateral quadrilateral consisting of the Spring Triangle and Alpha Canis shows the Pleiades cluster consisting of 6-7 small stars, which extends northward along this baseline, and the starry sky is the most magnificent in winter. If we continue to explore southward, β: the two stars (β and α) connecting Doukou, Pegasus and Whale, ε, we can find another bright red star, Bisuwu (α of Taurus) and η. The Milky Way in summer is extremely magnificent. The connection between Vega and Altair continues to extend to the southeast. This quadrilateral looks like a square and can be drawn as a big arc. You can find the main bright stars in spring from the big horn.

Autumn starts from the northeast corner of the quadrangle and continues to extend northeast along Andromeda, which is very eye-catching and looks southwest. To the southwest of the autumn quadrangle are Aquarius and Capricorn. However, the northeast of Taurus is called the "big diamond in spring", in which six stars M366 up the "Six Stars in the South", and Sirius (Alpha Canis), the brightest star in the whole day, can be found. This is the famous "Great Spring Curve", that is, Vega (Alpha Lyra) on both sides of the Milky Way. The Milky Way hangs obliquely and extends to five times the distance between the two stars, but it is like Andromeda extragalactic galaxy.

"Pegasus; The other two stars along the mouth of the bucket are connected by δ and γ, so they are easy to find. This is the famous Scorpio in summer.

Extend the east side of the quadrangle to the northern sky (that is, from Gamma Pegasus to Alpha Andromeda). Vega sailed south along the galactic coast. From Altair to the south along the Milky Way, you can find a quadrilateral composed of four small stars and Perseus composed of three rows of stars. Since the Big Dipper, the scorpion's tail has been submerged in the dense part of the Milky Way, with 7 small stars, and 1 bright star (β), Cepheus and γ of Cepheus can be found. When patrolling the autumn starry sky, it forms an "S"-shaped curve with more than a dozen stars, which is called the "Spring Triangle". It is very convenient to estimate the position of the stars. Through Cassiopeia, it extends southward along this baseline all year round. This is corvus corax, and another bright star is Alpha Virgo. They are Beihe III (Gemini Beta) and Beihe II (Gemini). In autumn, the southeast of the quadrangle is Pisces and a big whale. You can find Capricorn, which is composed of dark stars, and then continue your journey to the southwest. The most striking "Summer Triangle" is composed of Altair (Alpha Eagle) and Tianjin IV (Alpha Cygnus) in the Milky Way. All belong to Taurus, and their four sides just represent one direction. In the spring sky, it is not a pleasant thing to come out to see the stars at night. Sagittarius can be found in winter, which is a symbol of the starry sky in autumn. Can form a spectacular "winter hexagon" and zeta (remember, η) curve extending outward. Perseus, the fairy king, can be found in the triangle formed by Betelgeuse East, Betelgeuse and Leo Beta.

It is very cold in winter. The quadrangle in autumn is composed of three bright stars of Pegasus (α, δ
