Xinhua News Agency, Tianjin, July 13 (Reporter Zhou Runjian) July and August of each year is a good time to observe the galactic center (the center of the galaxy, that is, the intersection of the galaxy's rotation axis and the galactic plane) and the Milky Way in summer.
Astronomical science experts reminded that around midnight, in the suburbs far away from urban light pollution, the public in my country can enjoy the majestic appearance of the "upright Milky Way", which is the astronomical wonder of "the Milky Way down nine days."
"Let's go to Altair, Jiaojiaohe Han Girl", "The stars in the sky turn, the curtains on the earth hang down", "Late the bells and drums in the long night, the Geng Geng Xinghe wants to dawn".
Since ancient times, the beautiful and mysterious Milky Way has attracted people's attention and favor.
According to Xiu Lipeng, director of the Tianjin Astronomical Society and astronomical science expert, the Milky Way that people see with the naked eye is actually a part of the Milky Way. It is composed of a large number of stars. In ancient my country, there were beautiful names such as Xinghan, Tianhe, Jianghe and so on.
This mist-like light belt is majestic, with countless bright stars shining in it, and it also "owns" many famous constellations, nebulae and star clusters, which is highly ornamental.
Vega in Lyra, Tianjin Si in Cygnus, and Altair in Aquila form the famous "Summer Triangle".
In the suburbs far away from urban light pollution, you can use this eye-catching "big triangle" to find the beautiful Milky Way.
The Milky Way traverses this "Great Triangle" and extends north-south, and "flows" southward between Scorpio and Sagittarius. This is where the center of the Milky Way is located. The stars are densest and therefore appear the brightest.
"Generally speaking, in cities, as long as you avoid the interference of strong lights, it is not difficult to see the'Summer Triangle', but it is difficult to see the Milky Way with the naked eye," said Xiu Lipeng.
The Milky Way in summer usually refers to the "Cygnus-Aquila-Sagittarius" section of the Milky Way. June to September is a good time for observation.
"In our country, the brightest part of the galactic center can be seen just south of midnight in July and August every year, and the Milky Way extending upward from here is in an upright shape, dividing the sky into two. It is also the most majestic and majestic Milky Way in summer. , The most worthy of observation and shooting posture." Xiu Lipeng said.
Wang Junfeng, a veteran astronomer in Beijing, has made many observations of the Milky Way.
He said that considering factors such as sleep habits, climate and temperature, the best time to shoot the Milky Way in the northern hemisphere is from the end of May to the end of September each year, among which the "upright galaxy" has the most shocking effect.
"At midnight, the Milky Way is perpendicular to the south, like a sharp blade cutting the sky apart; and like a road connecting the sky and the earth. The Milky Way is curled up and the stars are shining like a magical world, which makes people feel infinitely emotional. "Wang Junfeng said.
Wang Junfeng also reminded that my country has a vast territory, with different latitudes and longitudes, and the vertical time of the Milky Way will be different.
Affected by latitude and altitude, the area where the galactic center is seen is also slightly different, and the area where the galactic center is seen is more complete in areas with lower latitude and higher altitude.
The interested public can integrate factors such as moon phase interference and rest days to develop more accurate observation and shooting plans.
"Tonight is a win for no one, lying down and watching the galaxy is full of meaning." In the midsummer season, cicadas and frogs scream, let us find a place far away from urban light pollution, under the poetic starry sky, have a "space-time dialogue with the beautiful Milky Way ", feel the magnificent posture of "Milky Way Falling Nine Heavens"!
