What astronomical phenomena can be observed in the sky next year?

According to the Korea Astronomical Research Institute on the 28th, there will be a penumbral lunar eclipse in May next year, in which the moon passes through the earth’s half shadow, and a partial lunar eclipse in October, when the moon partially covers the earth’s main shadow.

The penumbra lunar eclipse will begin on May 6, 2023 at 0:12 and end at 4:33.

A lunar eclipse occurs when the sun and the earth’s moon line up in a straight line, and the moon enters the earth’s shadow. The earth’s shadow is divided into the main shadow (base shadow), in which no sunlight is visible, and the semi-shadow (reflection), in which some sunlight is visible.

Unlike a partial or total lunar eclipse, a penumbral lunar eclipse is when the sun, earth, and moon do not line up in a straight line, but are offset, so that the earth is covered by a half shadow. In general, the Earth’s shadow is reflected on the moon’s surface faintly, so you may not be able to see it well with the naked eye.

The partial lunar eclipse on October 29 will start at 4:34:30 a.m. Seoul standard, reach its maximum at 5:14:06, and the entire process will end at 7:28:18. This partial lunar eclipse will be visible from Asia, Africa, Europe, Oceania and the Indian Ocean.

There are two solar eclipses in 2023 in which part or all of the sun is covered by the moon when the sun-moon-earth are in a straight line, but they cannot be seen in Korea.

There is a hybrid eclipse on April 20 and an annular eclipse on October 15. An annular eclipse is when the angular size of the moon is smaller than the angular size of the sun and does not completely cover the sun, and when the moon is completely inside the sun. means

At 20:00 on March 2, Venus and Jupiter, the two brightest planets in the night sky, will be within half a degree of close proximity and may appear to be nearly aligned. On March 24, there is an occultation of Venus that can only be observed in Jeju. Venus, which entered the region to the right of the moon at 21:14 on this day, comes out at 21:23.

In other areas, the crescent Moon and Venus can be seen very close, but at 19:28, the Moon and Venus can be seen close by 0.9 degrees.

Also known as the three meteor showers (an astronomical phenomenon in which many meteors look like rain), the Quadrantid meteor shower in January, the Perseid meteor shower in September, and the Gemini meteor shower in December can also be seen as usual.

The Quadrantid meteor shower, which comes first in the new year, is expected to be seen a lot on the night of January 3 and beyond midnight and the early morning of the 4th. was expected The peak time for the Gemini meteor shower is 4:00 on December 15th. It is a good environment to observe because the time of maximum is dawn and the sky is moonless all night.

Next year’s biggest full moon will be visible from August 31 to the dawn of September 1. On August 31, the Earth-Moon distance is about 357,300 km, which is about 27,199 km closer than the Earth-Moon average distance of 384,499 km. The smallest moon is the one that rises on February 6th.
