New Delhi, Sep 06, 2025: India is set to witness a spectacular celestial event on the night of September 7—a total lunar eclipse visible across the country. During this rare phenomenon, Earth’s shadow will glide over the Moon, turning it into a glowing copper-red disc, offering skywatchers an unforgettable visual treat.

A lunar eclipse occurs when Earth positions itself directly between the Sun and the Moon, casting its shadow on the lunar surface. The eclipse unfolds in stages: first, the Moon enters the penumbra, Earth’s faint outer shadow, followed by the umbra, the darker central shadow. As the Moon moves deeper into the umbra, it gradually darkens, culminating in a total eclipse when it adopts a striking red hue. This red color arises due to Rayleigh scattering: sunlight passing through Earth’s atmosphere loses its blue wavelengths, while red wavelengths bend around Earth, illuminating the Moon.

The totality phase on September 7 will last 82 minutes, providing ample time to enjoy the “Blood Moon.” Previous notable eclipses include the July 27, 2018, event, which lasted 103 minutes. Astronomers recommend open areas like terraces, rooftops, or parks for the best view, and binoculars or telescopes can enhance the experience. Unlike solar eclipses, lunar eclipses are safe to watch with the naked eye.

India’s ancient astronomer Aryabhata (476–550 CE) was among the first to scientifically explain eclipses, dismissing myths of ‘Rahu and Ketu.’ His calculations accurately predicted timing and nature of eclipses, laying the foundation for rational astronomical science in India. Modern organizations like the Astronomical Society of India and amateur astronomy clubs are encouraging public viewing and live streams to promote science literacy.

The Moon, beyond its visual beauty, plays a crucial role in life on Earth. Marine species, animals, and even humans have biological rhythms influenced by lunar cycles. Lunar eclipses also remind us of the cosmic connection between Earth and the wider universe.

India’s space agency, ISRO, has extensively studied the Moon through Chandrayaan missions, including water discovery and detailed mapping of the lunar South Pole. Plans for Chandrayaan-4 and the joint LUPEX mission with Japan will further explore the Moon’s extreme southern regions.
