Bengaluru residents will witness a captivating celestial phenomenon on Wednesday, April 24th, as the city experiences ‘Zero Shadow Day.’ This unique astronomical event occurs when the sun aligns perfectly overhead, causing vertical objects to cast no shadows. The Zero Shadow Day phenomenon is expected to transpire between 12:17 pm and 12:23 pm, offering an extraordinary opportunity to observe this celestial spectacle.
The Zero Shadow Day phenomenon occurs when the sun’s declination, the angular distance of a body north or south of the celestial equator, becomes equal to the latitude of a particular location. This alignment results in the sun reaching its zenith in the sky, positioned directly overhead, resulting in the absence of a shadow on the earth.
The Indian Institute of Astrophysics in Bengaluru will host events at its Koramangala campus on Zero Shadow Day to foster knowledge and understanding of this astronomical occurrence. From 10 am to 1 pm, students, teachers, and astronomy enthusiasts are invited to participate in hands-on activities, including observing the changing shadow lengths of objects and measuring them.
Zero Shadow Day is a testament to the intricate workings of our solar system and an opportunity to appreciate the harmony between celestial bodies. As the sun aligns perfectly overhead, casting no shadows for a brief period, it offers a glimpse into the precision and wonder of the universe.
