Solar and Lunar Eclipses & their characteristics
SOLAR AND LUNAR ECLIPSES & THEIR CHARACTERISTICS WHAT IS AN ECLIPSE? An eclipse occurs when a planet or moon obstructs the way of sunlight. On Earth, we can see two types of eclipse – Solar Eclipse and Lunar Eclipse. cnn.com SOLAR ECLIPSE Solar eclipses occur when the earth, moon and sun are in a straight line, i.e., moon obstructs the way of sun’s light entering Earth. There are 2 to 5 solar eclipses occurring every year. They only last for a few minutes. telescopeobserver .com TOTAL SOLAR ECLIPSE Total solar eclipse occurs when the moon completely covers the Sun when viewed from Earth. Total solar eclipse is limited to certain areas while other areas may see a partial solar eclipse. verge.com PARTIAL SOLAR ECLIPSE A partial solar eclipse is seen when the moon can only partially cover the Sun’s disk, the Sun and moon are not exactly in line with Earth. Partial eclipses may be unnoticeable due to the Sun’s brightness. gbtimes.com LUNAR ECLIPSE Lunar eclipse occurs when Earth comes in the way of sunlight falling on the moon and the Earth’s shadow covers the moon. Unlike Solar eclipse, Lunar eclipse can be seen at any night side of Earth and lasts for up to two hours. study.com TOTAL LUNAR ECLIPSE Total lunar eclipse occurs when Earth’s umbra, the dark, central shadow completely covers the moon. Light reflected during this eclipse from moon’s surface is the refracted light from Earth’s atmosphere. As a result, moon appears reddish and is also called the ‘blood moon’. cnn.com PARTIAL LUNAR ECLIPSE Partial lunar eclipse occurs when only a part of the moon is obscured by the Earth’s shadow. The Moon dims only slightly. earthsky.com RARE ECLIPSE The ‘Ring of fi re’ seen during an eclipse is a rare phenomenon, where the sun appears like a ring, with its center covered by the moon. The ‘Super blue blood moon’ is another rare lunar eclipse phenomenon which will be only seen next in 2033. bbc.co.uk CAUTION During Solar eclipse, never look directly at the Sun, as it can cause permanent eye damage. Special solar eclipse viewing glasses must be used. There is no harm for the eye in viewing the Lunar eclipse. britannica.com
