Striking astronomical events in September

The meeting of the planets, the Moon, the transition period between seasons are outstanding astronomical events this month.

When the night at the Northern Hemisphere began to grow in September, sky observers had a chance to admire some of the planets near Earth from dusk to dawn of the next day, according to National Geographic. . Venus flies closer to the Sun and becomes brighter, while the giant gas planet such as Jupiter and Saturn stands out in the southern sky. Both hemispheres cross the transition period, the northern hemisphere and the southern equinox in the southern hemisphere.

Venus met Spica star - September 1

About 30 minutes after the sun set, we could see two prominent bright spots next to each other near the western horizon, Venus and Spica, the brightest star of the Virgo constellation.

Venus, the second planet from the Sun, and the Spica star are only separated by about the width of two Moon discs. We can see this meeting more clearly with binoculars.

The moon meets a red giant star - September 3

If we look high up in the eastern sky just before dawn, we will see the crescent moon next to the red giant star Aldebaran, the main member of the constellation Taurus. By using binoculars, we can also recognize the distinct V-shape of the Hyades star cluster near Aldebaran.

- September 5

Zodiac light, or fake dawn, is a strange light source like a dim pyramid, extending from the eastern horizon in the fall, before the Sun rises. Observers can also see it in the west in the spring, after the Sun sets. In this case it is called fake sunset.

Since September 5, the sky has no Moon before dawn. Therefore, the next two weeks are the best opportunity for those who want to observe the zodiac light in the Northern Hemisphere.

Many people believe that the zodiac light originates from some phenomenon in the upper atmosphere of the Earth. However, it forms when sunlight reflects a multitude of dust particles flying around the Sun, belonging to the disk plane of the solar system (Earth and celestial bodies seem to spin around a disk-shaped plane with mind is the Sun). These dust particles remain in the process of forming Earth and other planets 4.5 billion years ago.

The moon lies next to Jupiter - September 13

When night falls, the crescent Moon will be right next to Jupiter at the lower part of the southwestern sky. Both heavenly bodies will dive under the horizon at 10 pm local time.

The moon meets Saturn - September 17

When the sunset falls, the Moon will appear above the yellow Saturn in the southern sky. Just below them is the Teapot star group of the Sagittarius constellation shaped like a tea kettle.

Grades - September 22

This equinox will happen at 8:54 pm on September 23, Vietnam time. This is the official time of the fall of the Northern Hemisphere and the southern hemisphere. The word "equinox" derives from the Latin "equal night" , referring to the same day and night time. Fecal and spring faeces are also the only days in the year the Sun rises in the East and dives in the West itself.

Pegasus - September 30

Looking at the northeast sky, we will see the appearance of the giant constellation Pegasus, also known as flying horse. This is the seventh largest constellation in the whole sky, and it is easy to see thanks to four bright stars forming a square, symbolizing the horse's body.
