The longest blood moon of the 21st century is about to occur next month, can Vietnam see?

You know what, the longest lunar eclipse of the 21st century will take place on July 27, when Earth’s shadow completely covers the Moon for 1 hour 43 minutes.

Please take a note pen straight from your calendar, which notebook because according to the Business Insider website, on July 27, 2018, many people around the world will have the opportunity to admire the extremely interesting astronomical spectacle.

He is looking at the blood moon or a total lunar eclipse. However, it will be the longest lunar eclipse of the 21st century – when the Moon is hidden behind Earth’s shadow for 1 hour 43 minutes, about 3 minutes longer than a total lunar eclipse that takes place at night. June 15, 2011.

It should be added that a Blood Moon or a Total Lunar Eclipse is a normal astronomical phenomenon when the Moon enters the Earth’s shadow and obscures the Sun’s light source.

But even if the Earth prevents all rays from the Sun reaching the Moon, these rays can still “slide” on the surface of the Earth and reflect on the Moon.

At the same time, the earth’s atmosphere as a giant focusing lens causes the passing red light to tend to deflect the main axis of the shadow. This light illuminated the Moon as it passed through this region. Therefore, we see that the Moon is red when the lunar eclipse takes place.

Although this is an extremely interesting astronomical phenomenon, according to experts at IFL Science, not everyone has witnessed this phenomenon.

The lunar eclipse can be observed most clearly in many parts of Africa, the Middle East, India, and parts of Europe. During this time, residents of North and South America will have no chance to follow the event. Vietnam is also lucky enough to be in the region to see the Blood Moon this time!

According to BusinessInsider, the total lunar eclipse will begin at 7:30 p.m. UTC on July 27, or 2:30 a.m. on July 28 (Vietnam time), and will end at 9:13 UTC (or 4:13 a.m. Vietnam time). The blood moon will peak at 8:22 p.m. UTC (or 3:22 a.m. on July 28, Vietnam time).

Due to the time when the blood moon is at dawn, those who love Vietnamese astronomy face some drawbacks. However, if you are truly passionate and interested in astronomy, be sure to prepare yourself well so that you don’t miss out on this amazing astronomical phenomenon.

It is known that in the last 100 years, only four total lunar eclipses with a total period can correspond to the event of this summer.

It was the lunar eclipse event of June 15, 2011 (100 minutes), July 16, 2000 (107 minutes), July 1982 (107 minutes), and July 1935 (101 minutes).

But why has this year’s Blood Moon phenomenon lasted so long?

This is because the Moon will pass near the center of the shadow (completely obscured area), which means it will stay behind the Earth’s shadow longer.

Earth is also at the furthest point from the Sun during the lunar eclipse, making its shadows larger than normal. And with the distance the farthest from the Earth should be even further inside the Earth’s shadow.
