A lunar eclipse, called Chandra Grahan in Hindi, happens when the Earth passes in front of the sun and the moon, causing the moon's surface to become shadowed. It only occurs during a full moon when the moon passes through the shadow cast by Earth. The moon seems to turn reddish-brown during this occurrence as a result of sunlight being scattered by Earth's atmosphere. Since ancient times, lunar eclipses have been watched, and they are said to have been connected to a number of superstitions and cultural beliefs. According to Hindu mythology, when there is a lunar eclipse, bad energy is at its strongest, therefore people perform prayers and rituals to ward off bad luck. From a scientific standpoint, lunar eclipses provide scientists a chance to examine the makeup and surface of the moon. They also aid in our comprehension of how the Earth's atmosphere affects sunlight. About twice a year, most places in the world offer views of lunar eclipses. People's curiosity and attention are continually piqued by this amazing cosmic occurrence.
