The total lunar eclipse that occurred today is the last one for the following three years. The Moon is completely hidden by Earth's shadow as the eclipse's total phase has started. This total phase will end at 5.12 PM Indian time while the partial phase of the eclipse will continue till 6.19 PM IST.
When the Earth passes between the Sun and the Moon, it creates a lunar eclipse by blocking some or all of the Moon's sunlight. As a result, the Moon's surface casts a shadow, which is what we can see from Earth.
The Moon will still get some sunlight during a total solar eclipse. Blue light will be scattered in all directions by a phenomenon known as Rayleigh scattering as it travels through the Earth's atmosphere. As a result, the Moon appears reddish during the eclipse because it can pass through and reflect the redder light.
The whole phase of the eclipse will be in process during moonrise in the Eastern regions of the country, including Kolkata and Guwahati, according to the Ministry of Earth Sciences. However, totality would not have been complete for other cities, such as Delhi, Mumbai, Chennai, and Bengaluru, until Moonrise.
In a few minutes, the lunar eclipse will reach its totality, or total coverage of the Moon by the shadow of the Earth. The Moon currently appears to be entirely obscured, as seen in the image below, however this is only because the dazzling reflection from the uncovered portion obscures the covered area. According to NASA scientist Noah Pedro, the same thing occurs when you see the eclipse with your eyes because of the way your brain interprets light.
