What constellations are there in summer?

Lyra is one of the most splendid constellations in the northern galaxy, named after its appearance resembling the ancient Greek harp. It is one of the 48 constellations listed by Ptolemy, an ancient Greek astronomer, and one of the 88 modern constellations designated by the International Astronomical Union.

Lyra is small, but it is not difficult to identify, because its main star Vega is one of the vertices of the "Summer Triangle". Seen clockwise from the north, Lyra is surrounded by Draco, Hercules, Fox and Cygnus.

From summer to autumn, Lyra can be seen from the northern hemisphere, and in summer, if you are in the temperate zone, Lyra is almost above your head. Seen from the southern hemisphere, Lyra can be seen at low altitude in the north in winter.

3. Sagittarius

Sagittarius is also a constellation of the zodiac. On a summer night, you can find it south from Altair in the constellation Aquila along the Milky Way. Because the galactic center is in the direction of Sagittarius, this part of the galaxy is the widest and brightest. Sagittarius is facing the center of the Milky Way, so there are many clusters and nebulae in it. Where the connecting line between σ and λ in Nandou doubles to the west, you can see a small cloud-like thing, which is actually a nebula. In the telescope, it is composed of three red dots, which is very beautiful and is called "trifid nebula".

4. Infinite constellation

The Five Immortals is a big constellation in the starry sky in summer night, and it is also one of several big constellations all day. Although the range of Wuxian is very large, it is a pity that the stars in the constellation are not very bright, and they are all composed of 3 stars and 4 stars. 1934, a nova burst was found in the constellation Ursa, with the brightness reaching 1, but it has become a dark star. 1960 and 1963 have new star bursts, but the brightness is not as bright as 1934.

5. Ophiuchus

In the summer night sky, located on the west side of the Milky Way, between Scorpio and Hercules, there is a very vast area with sparse stars, which is the location of Ophiuchus and Ophiuchus. Ophiuchus is a huge constellation. It is adjacent to Ursa major in the north, Scorpio in the south and Ophiuchus on both sides. The western end of Ophiuchus is close to the northern corona and Capricorn, and the eastern end is close to Eagle. Ophiuchus is half north of the equator and half south of it. It is the only constellation located in the ecliptic and not belonging to the ecliptic.
