Kalyan: In a fascinating display of astronomy and science awareness, citizens in Kalyan on Sunday enthusiastically witnessed the rare celestial phenomenon known as ‘Zero Shadow Day’ at Subhash Maidan. The special observation programme was jointly organised by Akash Mitra Mandal and Subhedarwada Katta, drawing a large number of students, science enthusiasts and amateur astronomers.

Unique Learning Experience for Students

The event turned into a unique learning experience as participants observed how, for a brief period objects cast almost no shadow when the Sun is positioned exactly overhead. The phenomenon sparked curiosity among attendees, especially students eager to understand the scientific principles behind the event.

Addressing the gathering, Hemant Mone, president of Akash Mitra Mandal and senior astronomy enthusiast, explained the science behind Zero Shadow Day in a simple and engaging manner. He elaborated on how the phenomenon occurs due to the Sun reaching the zenith position directly above a particular location on Earth, causing vertical objects to momentarily lose their visible shadows.
