New Delhi, Sept. 7 -- Skywatchers worldwide are in for a spectacular show on September 7-8, as a total lunar eclipse, popularly called a Blood Moon or Chandra Grahan, lights up the night sky. With its long total phase and wide visibility, this event promises to be one of the most phenomenal lunar displays in recent years.

During a total lunar eclipse, Earth moves directly between the Sun and the Moon, casting its shadow across the lunar surface. Instead of disappearing, the Moon glows deep red, giving it the iconic "Blood Moon" appearance. This vivid color is a natural phenomenon, caused by sunlight passing through Earth's atmosphere, filtering out shorter blue wavelengths and letting red and orange light reach the Moon.
