Summer is a good time to see the stars. Look west after dark and you will find Leo. To the east of Leo is Virgo. In the south of the sky, a bright red star shines in the lower sky. It is the main star of Scorpio and a bright star on the ecliptic. The obvious feature of Scorpio is that the three stars spread out in an arc at equal intervals, and Andromeda is located at the center of the circle. In ancient astronomy in China, Scorpio was a commercial star and Orion was a ginseng.
In the starry sky around Scorpio and Sagittarius, there is a white band of light, which is the Milky Way. Looking northeast along the Milky Way, you can see Vega and Altair, with two small stars on the left and right. The bright star that forms a triangle with these two bright stars is Tianjin IV, which forms a cross with other stars in Cygnus and is easy to identify.
At this time, the Big Dipper is in the northwest sky. After finding the constellation Capricorn, to the east, almost to the zenith, there is a semicircle constellation called Beiguan, just like a jewel-encrusted crown, where a large number of galaxies gather.
The starry sky in autumn night is clear and transparent, and it is also a good opportunity to see the stars.
On the southwest horizon, Sagittarius has been hanging there obliquely. The ancient book said that "Beidou declined south" refers to this. In the western sky, there are cowherd and weaver girl whispering, and Tianjin IV is also a light bulb there, but there is only a lonely bright star in the south. There are two bright stars rising in the northeast corner: Capella (the main star of Auriga) and Bisuwu (the main star of Taurus).
There are many princes and nobles in the autumn night sky: fairy king, fairy queen, fairy, fairy, flying horse and whale.
East of the zenith is Pegasus. Andromeda is a linear constellation in the northeast of Pegasus. To the north of Andromeda is the W-shaped Cassiopeia. To the west of Cassiopeia is Cepheus and to the east is Perseus.
The Great Lingwu in Perseus is a famous solar eclipse variable, and there is a long-period variable called Zenger in Cetacea.
Between Perseus and Cassiopeia is the Andromeda binary cluster. Andromeda has a famous big galaxy: Andromeda Nebula, which is much larger than the Milky Way and the nearest galaxy in the northern half of the day.
Although it is very cold in winter, the starry sky is extremely magnificent.
Orion is the center of the winter sky.
At the latitude of Xiamen, you can see three bright stars arranged neatly after dark, which is said by the people to be "three stars shining high". There are four bright stars around Samsung that form a rectangle with Samsung. This is Orion. Samsung is Orion's belt.
If you want to extend the connection of Samsung to the lower left, you will meet the brightest star in the whole day: Sirius, which is the main star of Canis Canis. Extending from Samsung to the upper right is the bright red star Bi Su Wu, and next to it is Capella.
Taurus is Gemini in the southeast, Cancer in the east and lion head in the east.
To the southwest of Orion is the long and big but very dim constellation Bojiang. Only in Guangdong can we vaguely see the southern part of Orion is the sky map and Tian Ge, and the southern part is the main star of Carina.
Below Orion's Samsung, there is a bright spot, which is the Orion Nebula. Next to the leftmost part of Samsung is the Horsehead Nebula. The Pleiades cluster in Taurus is an excellent open cluster, consisting of about 500 stars.
