| Solar Eclipse 2012 |
A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partially obscuring the image of the Sun as viewed from the Earth. An annular solar eclipse occurs when the Sun and Moon are exactly in line, but the apparent size of the Moon is smaller than that of the Sun, resulting to the so-called "ring of fire."
The phenomenon is said to occur rarely. The last recorded annular eclipse in the United States was on May 10, 1994 and the next one is projected to occur in October 2023.
NASA said that the annular eclipse on May 20-21 will be visible from within a narrow corridor along Earth's northern Hemisphere -- beginning in eastern Asia, crossing the North Pacific Ocean, and ending in the western United States.
In the Philippines, the event will be observed at its partial phase from 6:55-7:12 in the morning on Monday, May 21.
"For those traveling to the USA for the eclipse, please note that the eclipse occurs in the late afternoon of May 20 local time," NASA wrote.
As a reminder, experts say that one should not look directly at the eclipsed sun or he can get a serious eye injury. One should wear specially made protective glasses that is available for purchase online or create his own contraption by punching a small pinhole in a cardboard box.
