Solar Eclipse 101 | National Geographic
National Geographic・4 minutes read
A solar eclipse occurs when the moon blocks the sun's rays, with different types such as total, partial, annular, and hybrid. Safety precautions like certified eclipse glasses are necessary to avoid eye damage during viewing, and totality lasts for less than three minutes.
Insights
- The moon's orbit being tilted results in infrequent solar eclipses due to the specific alignment required for such an event to occur, where the moon blocks the sun's rays from reaching Earth.
- Total solar eclipses are the most remarkable type, visible only within the umbral shadow, lasting for less than three minutes. Safety measures like eclipse glasses are crucial to prevent eye damage, as the sun's rays can be harmful when directly looked at during an eclipse.

"Types and Safety of Solar Eclipses"
- A solar eclipse occurs when the moon moves between the Earth and the sun, blocking the sun's rays. The sun and moon appear the same size due to their distances. The moon's orbit is usually tilted, causing eclipses to be infrequent.
- There are four types of solar eclipses: total, partial, annular, and hybrid. A total eclipse is the most spectacular, only visible within the umbral shadow. Safety precautions include using certified eclipse-watching glasses or creating a pinhole viewer to avoid eye damage.
- Totality during an eclipse lasts for less than three minutes, during which it is safe to remove eclipse glasses. Animals and plants may exhibit behavior changes during an eclipse. The moon's gradual movement away from Earth will eventually prevent total solar eclipses in the distant future.
