2026年3月3日星期二将发生一次月全食。

lunar eclipse will occur on Tuesday, March 3, 2026. During a total lunar eclipse, the moon passes through three main phases. First, it enters the penumbral phase, where it begins to darken slightly as it moves into the Earth's outer shadow. Next, it enters the umbral phase, when the moon is fully covered by the Earth's central shadow, turning a reddish color due to the scattering of sunlight through the Earth's atmosphere. Finally, the moon exits the umbral shadow and re-enters the penumbral phase before returning to its usual brightness.
