Tuesday night will showcase a partial lunar eclipse during a supermoon, visible across the Western Hemisphere. The eclipse will occur between 8:41 p.m. and 12:47 a.m. Eastern time, with the maximum partial phase at 10:44 p.m. It will be visible in the United States, Canada, Latin America, the Caribbean, Africa, and Europe. Lunar eclipses happen due to the alignment of the sun, Earth, and moon, with this one causing the Earth's shadow to cover part of the moon's illuminated surface. The event will last about four hours and will be visible with the naked eye, with the most dramatic part lasting about an hour. This supermoon is the second of four consecutive supermoons this year, with the next two occurring in October and November. Additionally, a total lunar eclipse is expected in March next year.
