The eclipsed moon glows an eerie deep red color in a new photo of the total lunar eclipse that occurred earlier in May.
The European Southern Observatory (ESO) shared a new image of the Super Flower Blood Moon lunar eclipse, taken on the night of May 15 using telescopes at the ESO's Paranal Observatory in the Atacama Desert of Chile, according to a statement from the observatory.
A total lunar eclipse, which happens as the full moon moves into the deep umbral shadow of the Earth, was visible from parts of the Americas, Antarctica, Europe, Africa and the eastern Pacific on May 15 and 16. At the same time, the full moon had reached perigee — its closest to Earth of the month — making it a Super Blood Moon eclipse.

During a lunar eclipse, the Earth is positioned directly between the sun and the moon. As a result, the Earth blocks some of the sun's light and casts a shadow across the lunar surface. This, in turn, causes the moon to appear red as the sun's rays interact with Earth's atmosphere.
"Light from the sun contains a whole spectrum of colors. Blue light is dispersed by the atmosphere through a process called Rayleigh scattering (which makes the sky blue) while red light can pass through the atmosphere more easily, becoming slightly deflected," ESO officials explained in the statement. "This red light reaches the moon's surface, giving rise to its dramatic crimson hue."
The recent photo, shared by the ESO on May 23, was taken during totality, when the Earth blocks the most sunlight. It was photographed using an amateur-class telescope nicknamed UT5 at the Paranal Observatory.
The next full moon, called the full Strawberry Moon, will occur on June 14. It also happens to be the second supermoon of 2022. It will appear large and golden to viewers looking towards the southeast shortly after sunset.
