The list of celestial phenomena in 2022 has been released, there are four major celestial phenomena, seven stars and beads, blood moon, partial eclipse, and Mars opposition, especially the seven stars and pearls, which is a rare celestial phenomenon that will appear once in an average of 77 years, everyone wants to see what the seven stars and beads are like, it is estimated that they can only see once in a lifetime.
These four major celestial phenomena are indeed worth looking forward to, but the problem is that it takes a long time to appear, for example, the arrival time of the seven stars is June 16, 2022, we have to wait for half a year, in fact, in 2022, in addition to the four major celestial phenomena, there are many small celestial phenomena to see.
There is also a small celestial phenomenon before the arrival of the seven stars and pearls, you can see now, it is not noticed by the "Venus under the conjunction" of the celestial phenomenon, speaking of solar eclipse, lunar eclipse, seven stars and beads, I believe everyone knows what they look like, so what is the venus lower union? Let's first explain what Venus is.
Venus should be the second brightest celestial body in the night sky, the brightness is second only to the moon, more than the brightness of Jupiter, because Venus is located in the inner side of the Earth's orbit, relatively close to the sun, above the dome, Venus has been accompanied by the sun nearby, with the sun rising and falling, Venus appears on behalf of the sky is about to light up, so it is called "the star of enlightenment".
But now, the "day star" is becoming more and more eclipsed, and the light has become extremely faint, which means that the "venus conjunction" celestial phenomenon is about to come, and when Venus moves to the middle of the sun and the Earth's connection, the orbit of Venus does not necessarily completely coincide with the ecliptic plane, and there will be three situations.
First, Venus is located above the sun and the earth, and when Venus is viewed from the earth, Venus becomes a very small crescent, which is called the Venus conjunction, also known as the upper boundary of Venus.
Second, Venus is just located at the point where the sun and the earth are connected, and because Venus is facing away from the earth, we can only see the dark shadow of Venus passing by the surface of the sun, which is the transit of Venus.
Third, Venus is located below the sun and the earth connection, from the earth to see Venus, Venus also became a very small crescent shape, this situation is called Venus lower union, also known as the nether of Venus.
Venus conjunction time on January 9, 2022, now the distance between Venus and the Sun will be further shortened, astronomy enthusiasts in the telescope to see Venus is only 6 degrees away from the sun, this time to take pictures of Venus is also a very dangerous thing, a careless, strong sunlight will damage the precision telescope.
From the photos taken on January 6, Venus has become a very thin crescent-shaped, and with the passage of time, the crescent-shaped Venus will be further thinned, and it has to be said that this is also a kind of celestial phenomenon, but it is not as spectacular as the seven-star beads and the blood moon celestial phenomenon, and it is rarely mentioned.
On June 3, 2020, there was also a "Venus conjunction" celestial phenomenon, and many foreign astronomical enthusiasts took photos of the "Venus conjunction". The time of occurrence of the "Venus conjunction" can be calculated based on the orbit and speed of the Orbit of the Earth and Venus, and occurs about once every 19 months.
How do I see the celestial signs of Venus? Since Venus is now about to be located below the sun's connection with the Earth, from Earth, Venus is near the Sun, and the sunlight is so strong that it can only be seen before sunrise and after sunset, but the time to see is very limited.
When watching the celestial phenomenon under Venus, it is also necessary to choose a relatively open highland, no light pollution, so that the effect is better, of course, the naked eye is almost invisible, it is best to use a binoculars telescope, when using binoculars to see Venus, the most important thing to pay attention to is to be careful of strong sunlight.
