A rare total lunar eclipse, popularly known as a blood moon, will illuminate the night sky on Sunday, offering a striking view across Bangladesh and much of Asia.
The phenomenon will begin at 9:28 pm Bangladesh time, with the total eclipse lasting from 11:30 pm to 1:52 am before ending at 2:55 am on Monday, according to the Inter-Services Public Relations (ISPR).
Astronomers explain that a blood moon occurs when the Earth passes between the Sun and the Moon, casting its shadow on the lunar surface. Instead of disappearing into darkness, the Moon glows red because Earth’s atmosphere scatters shorter blue wavelengths of sunlight while allowing longer red and orange wavelengths to filter through—a process known as Rayleigh scattering.
NASA noted that the September 7–8 event will feature about 82 minutes of totality, making it one of the longest eclipses of the decade. The eclipse will be fully visible across Bangladesh, India, and China, and partially observable from eastern Africa and western Australia.
Unlike solar eclipses, lunar eclipses are completely safe to watch without any protective equipment. Skywatchers are advised to seek open spaces with minimal light pollution for the clearest view of the deep red Moon.
This marks the second total lunar eclipse of 2025, following one in March, with the next expected on March 2–3, 2026, according to NASA.
