2008 Solar Eclipse

Yes, around 18:00, Henan should be able to see a total solar eclipse~~~

According to astronomers’ calculations, there will be a total solar eclipse in my country on August 1, 2008. spectacle.

This is the first total solar eclipse to appear in my country in the new century. This total solar eclipse will begin in northern Canada, pass through the Arctic Circle, Russia, and Mongolia, and will enter my country through the Altai Mountains at 18:59 Beijing time. within the territory. It passes through Xinjiang, Gansu, Inner Mongolia, Ningxia, Shaanxi, and Shanxi, and ends in Luohe, Henan at sunset (19:21 Beijing time).

Since the duration of a total solar eclipse in a certain area is very short, with a maximum of only 7 minutes and 30 seconds, good weather conditions are extremely important for total solar eclipse observation. Experts analyzed that in August, Hami and Jiuquan areas are almost unaffected by the monsoon climate due to the obstruction of mountains. There are less clouds and scarce rainfall. The average daytime temperature reaches above 20°C and the maximum wind speed is only 25 kilometers. / hour, sandstorms rarely occur. The climate is extremely dry and sunny. Therefore, China's Hami and Jiuquan areas are the best places to observe the solar eclipse.

On July 22, 2009, a total solar eclipse will also occur in the vast areas of the Yangtze River Basin in my country. After entering my country from Tibet, the total eclipse belt swept across Yunnan, Sichuan, Hubei, Hunan, Jiangxi, Anhui, Jiangsu and Zhejiang provinces, lasting as long as 5 to 6 minutes. But the next total solar eclipse won't happen for another 25 years. Experts predict that a total solar eclipse will occur near the border of Xinjiang and Tibet in 2034. In 2035, the total eclipse belt will pass through major northern cities such as Beijing, Datong, and Qinhuangdao.

The so-called solar eclipse refers to the phenomenon that when the moon moves between the sun and the earth, people in the moon shadow area on the earth's surface see the sun being blocked by the moon. The ancients once described a solar eclipse as "a tengu eating the sun." In fact, the solar eclipse process is more like a circular plate moving from one side of the sun to the other to block it.

During a solar eclipse, people on the ground in the center of the moon's shadow will see a total or annular solar eclipse; people in the penumbra of the moon's shadow will see a partial eclipse. Experts say that although globally, two total solar eclipses can occur roughly every two or three years, for any specific location, it takes hundreds of years on average to see a total solar eclipse, and each total solar eclipse lasts the longest time. Only a few minutes.

A classic observation project that can be carried out during a total solar eclipse is to verify the deflection of light in the sun's gravitational field predicted by Einstein's general theory of relativity. The method is to take photos of the black sun and the surrounding stars, and then compare them with photos of these stars taken at night half a year ago or half a year later to observe whether the angular distance of these stars has changed.

If gravity causes the light to deflect, the starlight passing by the sun will change its direction slightly
