About 85 full eclipses took place during this entire 21st century (from 2001 to 2100) - Mr. Dang Vu Tuan Son, Vietnam Young Astronomical Club said.

>> The longest eclipse of the 21st century is coming

According to Tuan, the current statistics show that the longest eclipse of the total lunar eclipse will take place in July 2018 (we will have to wait 7 more years to witness this phenomenon). .

For the real moon that occurs on dawn on June 16, the darkness of the Earth will completely cover the Moon in a period of 100 minutes, only about 3 minutes less than the lunar eclipse taking place in 2018.

Can observe the lunar eclipse with the naked eye.

In Vietnam, according to NASA calculations: The half-moon eclipse will start at 0: 22 minutes on June 16, 2011 when the moon enters the half-dark shadow of the Earth, but the Moon half-moon will be very difficult. recognize because the Moon is only slightly darker than usual. The moment we should begin to observe is 1h22 ', the Moon will begin to enter the shadow area of ​​the Earth starting the partial eclipse, the color of the earth shadow area printed on the moon will gradually shift from black and gray to red when this shadow area grows.

The total eclipse will start at 2:22. The whole moon will turn red. The full moon actually peaks at 3h12 'is also when the moon is dyed with the best red color.

We will continue to observe the full lunar phase until 4h02 '. Then the moon will gradually come out of the dark, the color will return to normal until the moon leaves the shadow completely at 5h02 'and ends part eclipse.

Especially in 2011, there will be two full lunar eclipses that can be observed in Vietnam. On the evening of December 10, 2011, we will see the full lunar eclipse again, although the observation time is more favorable, but this total eclipse lasts only 52 minutes.
