On March 3, 2026, a total lunar eclipse, known as a blood moon, was visible across the Americas, eastern Asia, and Australia, turning the moon a copper-red as it passed through Earth's shadow. The eclipse lasted about 5.5 hours with totality near one hour. The UK missed the eclipse due to moonset timing. Additionally, a rare six-planet alignment occurred around February 28 and March 1, visible to the naked eye in many regions.
