Understanding Solar Eclipses

A solar eclipse occurs when the Moon moves between the Sun and Earth, casting a shadow on Earth, fully or partially obscuring the Sun's light in some areas.

There are four types: total, partial, annular, and hybrid. Total eclipses completely block the Sun, while annular eclipses leave a 'ring of fire' visible.

The path of totality is typically about 100 miles wide but can cross continents and oceans. Totality can last a maximum of 7.5 minutes, but is usually shorter.

Eclipses have influenced human history, causing fear or awe. Ancient civilizations often interpreted eclipses as supernatural events or omens from the gods.

Using the Saros cycle, a period of approximately 18 years, ancient astronomers could predict eclipses. The cycle's accuracy is due to the Earth, Moon, and Sun's orbital synchronicity.

Eclipses have advanced scientific knowledge. The 1919 eclipse supported Einstein’s theory of relativity by confirming light bending around the Sun.

Never look directly at the Sun without proper eye protection. Special eclipse glasses must meet the ISO 12312-2 international safety standard to prevent eye damage.

Lunar eclipses can occur without being visible from Earth, known as 'penumbral eclipses,' where the Moon passes through Earth's faint outer shadow.
