Skygazers will be able to witness the first total lunar eclipse of 2021 on May 26. This is the first total lunar eclipse after 2019. Total lunar eclipse 2021 is known as the Blood Moon or the supermoon since the moon appears reddish-orange.
Blood Moon takes place only when the Earth comes between the Sun and the Moon to block Sun rays from reaching the moon on a lunar eclipse. NASA explained. “When this happens, the only light that reaches the Moon’s surface is from the edges of the Earth’s atmosphere. The air molecules from Earth’s atmosphere scatter out most of the blue light. The remaining light reflects onto the Moon’s surface with a red glow, making the Moon appear red in the night sky.”
