Which part of the sun is visible during a solar eclipse?
Introduction
A solar eclipse occurs when the moon passes between the sun and Earth and blocks all or a portion of the sun's light. This phenomenon results in a temporary darkening of the sky as the moon casts a shadow on Earth. During a solar eclipse, only a certain portion of the sun is visible.
What part of the sun is visible?
During a solar eclipse, the part of the sun that is visible depends on the type of solar eclipse. There are three types of solar eclipses:
- Partial eclipse
- Total eclipse
- Annular eclipse
Partial eclipse
During a partial eclipse, the moon passes between the sun and Earth, but does not completely block the sun's light. As a result, only a portion of the sun's disk is visible. The visible part of the sun appears as a crescent shape that gradually becomes smaller as the eclipse progresses.
Total eclipse
During a total eclipse, the moon completely blocks the sun's disk, and only the sun's outer atmosphere, known as the corona, is visible. The corona is a faint, pearly-white layer of plasma that surrounds the sun and extends millions of kilometers into space. The corona can only be seen during a total eclipse because it is much dimmer than the rest of the sun's disk.
Annular eclipse
An annular eclipse occurs when the moon passes between the sun and Earth, but is too far away from Earth to completely block the sun's disk. As a result, a bright ring of sunlight, known as an annulus, is visible around the moon. The visible part of the sun during an annular eclipse appears as a bright ring around the moon.
Conclusion
During a solar eclipse, only a certain portion of the sun is visible, depending on the type of eclipse. A partial eclipse shows only a crescent shape, while a total eclipse shows the sun's corona, and an annular eclipse shows a bright ring around the moon.
