A total lunar eclipse — the longest since 2022 — was fully visible across every part of India on the night of September 7–8, 2025. The eclipse had a magnitude of 1.368, making it a deep total eclipse. During totality, Earth's atmosphere bent sunlight and filtered out blue wavelengths, causing the Moon to glow a coppery red, commonly called a 'Blood Moon'. This was the first eclipse visible from all corners of India since July 27, 2018. The eclipse coincided with Pitru Paksha, the 15-day Hindu period for honouring ancestors, adding religious significance. Scientists noted that the hue and brightness of the Moon during totality provides data on dust and aerosol levels in Earth's atmosphere. The Moon was transiting Shatabhisha Nakshatra in Kumbha Rashi (Aquarius) at the time of the eclipse.

Frequently asked questions
When was the total lunar eclipse visible across India in 2025 and what made it notable?
The total lunar eclipse was visible across all of India on September 7-8, 2025, and it was the longest total lunar eclipse since 2022. The Blood Moon had a magnitude of 1.368, making it a particularly deep and visually striking eclipse.
What is a Blood Moon and what causes it?
A Blood Moon occurs during a total lunar eclipse when the Earth comes between the Sun and Moon, and sunlight refracts through Earth's atmosphere casting a reddish glow on the Moon. The red colour is caused by the same Rayleigh scattering that produces red sunrises and sunsets.
What is the eclipse magnitude of 1.368 and what does it indicate about the September 2025 lunar eclipse?
Eclipse magnitude refers to the fraction of the Moon's diameter covered by the Earth's umbral shadow. A magnitude of 1.368 for the September 2025 lunar eclipse indicates it was a deep total eclipse, with the Moon passing well inside the darkest part of Earth's shadow, resulting in a vivid red Blood Moon appearance.
What is Pitru Paksha and why was its coincidence with the September 2025 lunar eclipse culturally significant?
Pitru Paksha is a 16-day Hindu observance period during which people pay homage to their ancestors through rituals like Shraddha and Tarpan. The coincidence of the total lunar eclipse with this period in September 2025 was considered significant by many Hindus, as eclipses traditionally hold religious importance in Hindu custom.
What scientific value did the September 2025 total lunar eclipse provide to researchers?
Scientists collected valuable atmospheric data during the September 2025 total lunar eclipse by analysing the spectrum of sunlight refracted through Earth's atmosphere and projected onto the Moon. This data helps study the composition and aerosol content of Earth's atmosphere, and similar techniques are used to study exoplanet atmospheres.
