A Celestial Spectacle Unfolds
At 9:57 PM IST on September 7, 2025, the night sky over India comes alive with the partial phase of the Chandra Grahan 2025, a total lunar eclipse promising an 82-minute ‘Blood Moon’—the longest since 2022. As enthusiasts across India, Australia, the Far East, the Middle East, Europe, and parts of Africa prepare to gaze upward, this second and final lunar eclipse of the year offers a rare cosmic treat. With the total phase peaking at 11:58 PM and lasting until 12:23 AM on September 8, the event blends science and cultural significance, drawing millions to witness nature’s grandeur.
The Eclipse Timeline and Visibility
The lunar eclipse kicks off with its penumbral phase at 8:58 PM, transitioning to a partial phase at 9:57 PM. Niruj Mohan Ramanujam from the Indian Institute of Astrophysics confirms the total eclipse will span 11:01 PM to 12:23 AM, with the partial phase ending at 1:26 AM and the event concluding at 2:25 AM. Visible to the naked eye under clear skies, this spectacle will elude the Americas but captivate Asia and beyond. In India, temples like Badrinath and Kedarnath have closed for darshan, with Ganga Aartis shifted to the afternoon in Haridwar due to the Sutak period starting at 12:58 PM.
The Science Behind the ‘Blood Moon’
The striking reddish hue, dubbed the ‘Blood Moon,’ results from sunlight refracting through Earth’s atmosphere during the total eclipse, as explained by IIA scientist Niruj Mohan Ramanujam. This phenomenon, visible from 11:01 PM to 12:23 AM, turns the moon a deep coppery red, captivating viewers. OP Gupta from Nehru Planetarium assures it’s safe to watch without protective gear, adding to the event’s accessibility.
Example: In Delhi, clear skies at 9:27 PM revealed early moon visuals, setting the stage for the peak at 11:48 PM.
