Last weekend's crescent moon shape next to Mars and the last month brightens as a moon this week, passing through Cancer and passing through Leo. As the moon gets bigger, it also means that the number of stars that can be seen decreases. For the time being, it won't be easy to find stars of rank 5 or 6, even in rural skies.
But there is no need to be too sad. This is because there are opportunities to see more shooting stars than usual during this week. The best time to see a shooting star is around 4 am, before the moon and dawn. Those who wish to see a shooting star and make a wish should wake up a little earlier than usual during this week and see the dawn sky.
The protagonist of this week's constellation tour is the constellation Crow, seen above the southern horizon. Go south along with the handle of the Big Dipper and descend along with the bright first-class castles of the constellation of Shepherd and Virgo, and you will see the constellation of the crow in the shape of a trapezoidal shape. Although it is a small constellation, the stars of about 3 stars have a distinct shape like a sailboat floating on the sea, so it is not difficult to find. According to Greek mythology, a crow with beautiful fur was punished by the sun god Apollon and turned black. This week, let's find the crow constellation and find out why the color of the crow's fur has turned black.
Geomungozari meteor shower (4.22~4.23)
From midnight on this Thursday to early morning on Friday, the Lyra meteor shower appears, with up to 20 shooting stars falling per hour around the constellation Lyra. Meteor shower refers to a phenomenon in which more shooting stars than usual are poured out as the debris remaining in the comet's orbit collides with the Earth's atmosphere when the earth passes through the orbit of the comet.
Because the Earth orbits are almost constantly, meteor showers appear at about the same location and at the same time each year. However, you can see more shooting stars in the early morning hours than in the evening hours. This is because when you think of the earth as a bus running, the part that corresponds to the windshield is the area where dawn comes. However, the number of shooting stars you can see varies depending on the darkness of the sky and the weather, so you should find the darkest sky as much as possible.
Meteor showers with more than 20 shooting stars per hour appear eight times a year, and among them, the three largest meteor showers are known as a quadrant meteor shower (January 4), Perseus meteor shower (August 13), Gemini meteor shower (December) On the 14th), up to 100 or more shooting stars may fall per hour.
The comet that makes the Geomungo meteor shower is Comet Thatcher, which orbits the sun with a cycle of 415 years. The comet's most recent approach was 1861, followed by 2276. The geomungo constellation meteor shower is one of the oldest meteor showers known to date. It was first observed in 687 B.C.E. There are times when about 100 meteors per hour drop every decade, but there is no special periodicity.
The time when the Earth meets the orbit of Comet Thatcher is around 10:00 pm on the 22nd in Korea, but the time when you can actually see a shooting star is after midnight when Korea is located in the front part of the orbit. In particular, it is expected that the best time to see a meteor shower will be from after the sun sets at around 3 a.m. to around 4:30, about an hour before the sun rises.
The meteor shower does not necessarily appear in the geomungo constellation. Shooting stars scatter in all directions around the radiant point in the constellation Lyra (the point where the comet's orbit meets). Good to see.
A constellation that resembles a sailboat, Crows
In the evening, when the Big Dipper ascends to the highest point in the northern sky, all the constellations of the spring settle. However, as the moon moves to the constellation of Leo, there are no stars in the southeastern sky other than the bright first stars in the constellations of Leo, Shepherd, and Virgo. Constellations in spring, made up of faint stars less than 4 stars, are hardly found in the moonlight.
However, as you descend into the southern sky along with the curved handle of the Big Dipper, you will pass two bright first stars and meet a distorted square constellation made up of third stars near the horizon. This constellation is the constellation crow, which makes the illusion that a small sailboat is floating alone in the sea at night.
In the constellation Crows, it is recorded as the tail star of the Jujak (red phoenix) that protects the southern sky in the ancient star map of Korea [jin (軫) number, which is the last 28th out of 28 numbers)]. It is very interesting that the Western crow was called the tail of the phoenix in Korea.
According to Greek mythology, the crow was a beautiful bird with silver wings. It was also a clever bird that could speak human words. The crow was especially loved as a pet of the sun god Apollon, but it is said that the god Apollon burned her wings black and threw them into the sky for the sin of killing her by falsely reporting the infidelity of his lover, Coronis.
The crow is also known to be related to the constellation of the cup and the constellation of the sea snake. The god Apollon once blew away the crow he had raised to drink water from a distant spring. On the way, the crow found a fig tree, where the greedy fruit began to run, and, forgetting the command of the god Apollon, waited in the shaded leaves of the fig tree until the fruit ripened. After a while, the crow, who had eaten ripe figs, caught a snake near the spring and brought it back to the god with a cup of water. When the reason for the crow's lateness was to be attributed to the snake, the god Apollon, who already knew it, could not stand anger and threw the crow, the snake, and the cup all into the sky. The cup constellation next to the crow constellation and the sea snake is said to be a water cup and a snake thrown into the sky at that time.
In addition, there is a story in the Bible that one of the jackdaws that Noah sent out became this constellation. The crow, who was wandering without finding a place to rest, went up to the sky and sat down on the constellation of sea snakes.
