A year is about to pass, a new year is approaching. Let’s find out what interesting astronomical events await us in August 2021.
This ephemeris document is mainly translated from the Seasky site, and also references many reputable scientific sites such as Earthsky, NASA, Time & Date, etc. The times of astronomical events in the article are all converted to Vietnamese time.
As usual, the first month of the year opens with the rather large Quadrantid meteor shower.

August 2 – Saturn in opposition
Saturn will then be closest to Earth and its surface will completely reflect the Sun’s light back to Earth. This makes it the brightest of the year and visible to the naked eye all night. This is the best time to photograph and observe Saturn and its satellites. A medium to large telescope will help you see Saturn’s rings and some of its brighter moons.
August 8 – New Moon
The Moon will be in the same direction as the Earth and the Sun, making it impossible to observe in the night sky. This phenomenon occurred at 1:51 p.m. UTC (8:51 p.m. Vietnam time). This is the best time of the month to observe faint objects such as galaxies and star clusters, as they are not affected by the Moon’s light.
August 12-13 – Perseid meteor shower
The Anh Tien meteor shower is one of the most beautiful meteor showers of the year, with a frequency of up to 60 rays of light per hour at its peak. The Anh Tien meteors come from the Swift-Tuttle comet, discovered in 1862. Anh Tien is famous for the large number of bright meteors streaking across the sky. The meteor shower usually occurs every year from August 17 to 24. The peak in 2021 will occur on the night of August 12 and the morning of August 13. The crescent moon at the start of the month will leave skies dark, creating conditions for viewing this year. The best viewing locations are in dark areas after midnight. Meteors tend to appear in the constellation Eros, but can appear anywhere in the sky.

August 19 – Jupiter is in opposition
This giant planet will be closest to Earth and its surface will completely reflect sunlight back to Earth. Jupiter will be brightest at this time of year and can be observed all night. This will be the best time to photograph and observe Jupiter and its moons. A medium-sized telescope will show you Jupiter’s cloud stripes. A good pair of binoculars will allow you to observe Jupiter’s four largest moons, which appear as bright spots next to the planet.
August 22 – Full Moon, Blue Moon
The Moon will be in a position opposite the Earth and the Sun, its surface will completely reflect sunlight back to the Earth. This phenomenon occurred at 12:02 UTC (7:02 p.m. Vietnam time). This full moon was first known by indigenous tribes in the Americas as the Sturgeon Moon, because sturgeon in the Great Lakes and other lakes became easier to hunt around this time. This full moon is also known by other names such as the Green Corn Moon or the Grain Moon. Because it is the third of four full moons of fall, it is also known as the Blue Moon. This rare phenomenon only occurs once every few years, hence the expression “once in a blue moon” to describe a very rare event. Normally there are only three full moons per season, but since the moon is full every 29.53 days, there are sometimes four full moons per season (on average every 2.7 years). This special full moon will be called the Blue Moon
