Lunar Eclipse – Rare Celestial Event at Full Moon
A lunar eclipse occurs when Earth is positioned between the sun and the moon, casting its shadow on the moon.
Things worth knowing about "Lunar Eclipse"
A lunar eclipse occurs when Earth passes directly between the sun and the moon, causing the moon to move into Earth’s shadow. This rare event can only happen during a full moon.
Depending on the alignment, it can be a total, partial, or penumbral lunar eclipse. During a total lunar eclipse, the moon often takes on a reddish hue due to the scattering of sunlight in Earth’s atmosphere. The exact shade of red depends on air quality and can be intensified by dust particles or volcanic ash.
Lunar eclipses are visible worldwide, as long as the moon is above the horizon. They are safe to view with the naked eye and are popular for astronomical observation and photography.
