According to Space , the central band of the eclipse that astronomy enthusiasts are most looking forward to this year is only about 185km wide, 16,000km long and passes through North America and Central America. This means that astronomy enthusiasts in Vietnam cannot observe this phenomenon.
Millions of people in northern Mexico, the United States and southeastern Canada will have the opportunity to observe a total solar eclipse with darkness covering the morning sky on April 8 at 10:50 a.m. local time (about 10:50 p.m. April 8 Vietnam time). The first area of the eclipse is determined to be the city of Mazatlan, Mexico.

In addition, most people in North America (except Alaska) as well as Central America and the northernmost part of the South American continent will have the opportunity to observe a partial solar eclipse.
The eclipse will end in Canada's easternmost province of Newfoundland and Labrador at 2:48 p.m. local time (early morning April 9, Vietnam time).
Total solar eclipse once in a hundred years
The National Aeronautics and Space Administration (NASA) said that the solar eclipse on April 8 is a "once in a century" astronomical phenomenon for many reasons.
First, it is a total eclipse that will last 4 minutes and 28 minutes in Mexico, the longest recorded eclipse in North America in 45 years. Many people will have the opportunity to observe this phenomenon because the eclipse will pass through densely populated areas in 14 US states.
Second, the eclipse occurs at the time of the sun's most active period in its 11-year cycle - known as solar maximum - so the corona surrounding the "black sun" will be larger, clearer and more magical.
Third, the "demon comet" 12P/Pons-Brooks may appear at the same time as the bright halo that forms the shape of a horned devil's head. At that time, the comet will be relatively close to Jupiter.
The last time a comet was observed during a total solar eclipse was on December 14, 2020 in Argentina and Chile.
Fourth, there will be a "double diamond ring" phenomenon. The "diamond ring" effect is an optical phenomenon that occurs just before and after the sun is completely obscured by the moon, due to a small amount of sunlight passing through the gaps between the mountains on the sun.
This will create a bright ring of light around the moon as well as a "diamond" perched on one side.

What is a total solar eclipse?
A total solar eclipse occurs when the moon passes between the sun and the Earth, completely blocking the sun's surface, NASA says. People viewing the eclipse from locations where the moon's shadow completely covers the sun, known as the eclipse path, will experience a total solar eclipse.
During a total solar eclipse, the sky will become dark during the day. Weather permitting, people living along the path of a total solar eclipse will see the sun's corona, or outer atmosphere, which is normally obscured by the sun's bright surface.
If you have the opportunity to observe a solar eclipse, you should follow these safety guidelines when viewing this astronomical phenomenon. The only time it is safe to view a solar eclipse without protective eyewear is when the moon completely blocks the sunlight.
Viewers should use special glasses to view the eclipse. If using handheld devices such as telescopes, binoculars or cameras, a solar filter is required.
