If you could look up at the sky at 7 pm, which constellations would you see? 8 o'clock, 9 o'clock, 10 o'clock?

In hot summer, people feel uncomfortable. However, in this season, flowers and plants are flourishing, and the night sky is full of stars, which makes people feel full of vitality everywhere. Therefore, we might as well enjoy the cool outdoors, look at the stars and feast our eyes.

How do we find the summer constellation? This question is very simple, of course, starting with the representative of summer. What is the representative of summer? It is the "Summer Triangle", which consists of Vega in Lyra, Altair in Aquila and four or three first-class stars in Tianjin in Cygnus. Vega is the brightest, followed by Cowherd and Tianjin IV. Take the Weaver Girl and Tianjin IV as the axis and turn to the Summer Triangle to find the North Star. With Weaver Girl and Cowherd as the axes, you can find the bright star of Ophiuchus-Hou (α star) by flipping the Summer Triangle. Ophiuchus is shaped like a house. There are not many stars in the middle of this house, so it is not difficult to find it, although it is vast.

Next to Ophiuchus, we can find the head and tail of Ophiuchus, which is the only constellation divided into two parts.

From Cowherd to Weaver Girl, you can find Draco's head. From the Weaver Girl to the waiting place, you can find the heart of Scorpio-Antares I (Alpha Star), which is a first-class bright star. Scorpio is shaped like an "S". You can find it as long as you look up at the southern sky.

In the east of Scorpio, we can find Sagittarius. Sagittarius has six stars in the shape of the Big Dipper, that is, "six stars in the south bucket". The bright stars of Sagittarius form a very interesting figure-a big teapot, and the Milky Way just flows through this constellation. Isn't it like the water poured out of this big teapot in the sky?

We can find Libra in the west of Scorpio. Between Draco and Ophiuchus, we can find Wuxian. The arrangement of the stars in Wuxian county has a great feature, that is, the stars are H-shaped, which is a very important clue!
