"May 5th Lunar Eclipse: Where, When, and How to Watch"

On May 5, 2023, a penumbral lunar eclipse will occur, visible in Africa, Asia, Australia, and large portions of Europe. The eclipse occurs when the Earth gets between the Sun and the Moon and casts part of its shadow on the Moon. The Moon will dim slightly as it passes through the lighter part of the Earth's shadow, known as the penumbra. Lunar eclipses occur when the Moon passes through the Earth's shadow, which is not always uniform. The upcoming event is the first of a number of eclipses occurring over the next year.
