Another year is coming to an end, the new year is approaching. Let’s find out what exciting astronomical events await us in April 2021.
This astronomical calendar document is mainly translated from the Seasky website, in addition to many reputable scientific websites such as Earthsky, NASA, Time & Date, etc. converted to Vietnamese time.
April 12 – New Moon
The Moon will be on the same side of the Sun as the Earth and will not be visible in the night sky. This phase will take place at 9:30 a.m. This is the best time of the month to observe faint objects such as galaxies or star clusters as they are unaffected by moonlight.
April 22 and 23 – Lyrid meteor shower
Lyrids are medium-sized meteor showers, typically producing 20 meteors per hour at their peak. It was created by dust particles left behind by comet C/1861 G1 Thatcher, discovered in 1861. This star shower occurs every year from April 16 to 25. This year’s peak is on the night of the 22nd to the 23rd. These shooting stars can sometimes create bright dust trails that last a few seconds. The problem this year is that the moon is almost full. Its brilliant light will obscure all but the brightest star trails. But if you’re patient, you’ll probably still be able to catch a few loose leads. Best observed in a dark place after midnight. The meteor will come from the constellation of Lyra, but can appear anywhere in the sky.

April 27 – Full Moon, Super Moon
The Moon will appear on the opposite side of the Sun to the Earth and its surface will be fully illuminated. This phase takes place at 10:33 a.m. Native American tribes in ancient America called this phase of the full moon the pink moon because it marked the appearance of pink moss, also known as wild oleander, which is one of the first flowers to bloom. in spring. This moon phase is also known as Grass Moon, Growth Moon, and Egg Moon. Many coastal tribes call it Fish Moon because it is the time when thick herring swim upstream to lay eggs. It’s also the first of three supermoons for 2021. The moon will be closest to Earth and will likely appear slightly larger and brighter than usual.
