2025 in science

partial solar eclipse

A total lunar eclipse occurred at the Moon's ascending node of orbit on Sunday, September 7, 2025, with an umbral magnitude of 1.3638. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A total lunar eclipse occurs when the Moon's near side entirely passes into the Earth's umbral shadow. Unlike a solar eclipse, which can only be viewed from a relatively small area of the world, a lunar eclipse may be viewed from anywhere on the night side of Earth. A total lunar eclipse can last up to nearly two hours, while a total solar eclipse lasts only a few minutes at any given place, because the Moon's shadow is smaller. Occurring about 2.6 days before perigee, the Moon's apparent diameter was larger.

A partial solar eclipse occurred at the Moon’s descending node of orbit on Sunday, September 21, 2025, with a magnitude of 0.855. A solar eclipse occurs when the Moon passes between the Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A partial solar eclipse occurs in the polar regions of the Earth when the center of the Moon's shadow misses the Earth.
