China News Service, Nanjing, July 2 (Reporter Yang Yanci) According to the Purple Mountain Observatory of the Chinese Academy of Sciences on the 2nd: Starting this month, the bright summer triangle and the summer Milky Way will be beautifully unveiled.
In addition, several large planets visible to the naked eye are simultaneously ushering in a "best time" for appreciation.
The summer triangle refers to the triangle formed by Vega in Lyra, Tianjin Si in Cygnus, and Altair in Aquila at high altitude in the southeast in summer.
In the city, as long as you avoid the interference of strong light, you can see this brilliant “geometrical picture” of the sky curtain when you look up.
From this beautiful "big triangle", there is a chance to find a brilliant Milky Way.
The so-called summer galaxy refers to summer nights when the weather is fine and the light pollution is small. There will be a milky white band of light across the sky and across the north and south. The large and small constellations are shining and the stars are shining.
The planetary "show" this month is equally exciting.
On July 3, the Venus conjoined honeycomb cluster will be the first to appear.
Throughout July, the observation conditions of Venus were very good, and its brightness could reach -3.0 magnitude.
After sunset, it is easy to find Venus at low altitude in the west.
The honeycomb star cluster is an open star cluster with about 1,000 members.
On the evening of the 3rd, the angular distance between Venus and the hive star cluster was very close.
The public can use the bright Venus as a reference, and the honeycomb star cluster can be found not far away.
After Venus "visited" the hive star cluster on the 3rd, it will conjoin the moon on the 12th and Xuanyuan 14 on the 22nd.
After sunset on the 12th, the moon, Venus, and Mars will "converge" in the western sky.
After the "naughty" Venus continued to "slowly move" for 10 days, it "meeted" with Xuanyuan Fourteen on the 22nd.
According to astronomers, Xuanyuan Fourteen is also called Alpha Leo, which is the brightest star in Leo.
At that time, the bright Venus and Xuanyuan Fourteen will "hand in hand" to shine together in the night sky.
At the end of July, a romantic δ Aquarius southern meteor shower struck.
The delta Aquarius southern meteor shower is also called the delta Aquarius meteor shower. The active period is from July 12 to August 23, and the period is longer.
Its peak period this year occurred on July 30, and it is expected that ZHR (the maximum zenith flow per hour) can reach 25.
It is worth mentioning that in the days before and after the end of July, in addition to the delta Aquarius southern meteor shower, the alpha Capricornus meteor shower, the Anus meteor shower, and the Perseid meteor shower are all active.
Although the flow of a single meteor shower is not large, but superimposed together, it will present a better viewing effect.
