While the recent solar eclipse was not visible across Bangladesh and much of South Asia, stargazers now have another cosmic treat to anticipate: a total lunar eclipse. Unlike the solar event, this celestial spectacle will be observable in Bangladesh, albeit for a short duration.
What is a Lunar Eclipse?
The Moon does not emit its own light. Its glow comes from sunlight reflected off its surface. A lunar eclipse occurs when the Earth moves directly between the Sun and the Moon, casting its shadow on the Moon. During a total lunar eclipse, the Moon often turns a striking red, earning it the popular nickname “Blood Moon.”
Unlike solar eclipses, which require special glasses to view safely, lunar eclipses are safe to watch with the naked eye. The event typically lasts several hours, providing ample time for observation.
When and Where to Watch
The upcoming eclipse will occur on 3 March, and will be visible from regions of the Earth where night prevails. Both Bangladesh and India will witness the event, though the total eclipse will last for a shorter period locally.
| Location | Eclipse Type | Start Time | Totality Start | Totality End | Partial End |
|---|---|---|---|---|---|
| Bangladesh | Total & Partial | 17:28 | 17:28 | 18:02 | 20:23 |
| India | Total & Partial | 16:58 | 16:58 | 17:32 | 19:53 |
| USA (Western States) | Total | 04:04 (3 Mar) | 04:04 | 05:02 | – |
The entire eclipse will span nearly five hours, with the most dramatic total phase lasting 58 minutes and 15 seconds. Observers in Bangladesh can see this remarkable transformation as the Moon gradually darkens and takes on its reddish hue.
Why Does the Moon Turn Red?
During a total lunar eclipse, the Moon never turns completely black. Instead, it appears deep red. This phenomenon occurs because sunlight passes through the Earth’s atmosphere, which scatters shorter blue wavelengths and allows the longer red wavelengths to reach the Moon. The result is a captivating dark crimson glow across the lunar surface, visible even without telescopes.
This lunar spectacle offers an accessible and enchanting opportunity for astronomy enthusiasts across Bangladesh and neighbouring regions. So, mark your calendars for the evening of 3 March and experience the Blood Moon in all its glory.
