2023 October 29
Two images of a partial lunar eclipse are shown. On the left  the image is overexposed everywhere except the bottom right where  the eclipsed part of the Moon is visible. On the right image most  of the image is normally exposed but the bottom right part is dark.  Please see the explanation for more detailed information.

Explanation: What's happened to the Moon? Within the last day, part of the Moon moved through the Earth's shadow. This happens about once or twice a year, but not every month since the Moon's orbit around the Earth is slightly tilted. Pictured here, the face of a full Hunter's Moon is shown twice from Italy during this partial lunar eclipse. On the left, most of the Moon appears overexposed except for the eclipsed bottom right, which shows some familiar lunar surface details. In contrast, on the right, most of the (same) Moon appears normally exposed, with the exception of the bottom right, which now appears dark. All lunar eclipses are visible from the half of the Earth facing the Moon at the time of the eclipse, but this eclipse was visible specifically from Europe, Africa, Asia, and Australia, clouds permitting. In April, a total solar eclipse will be visible from North America.
