On this particular early version of This Week in Astronomy, we look forward to this weekend’s partial lunar eclipse.

In a partial lunar eclipse, the deepest a part of the Earth’s shadow — the umbra — solely partially covers the Moon. This time, that can be finest seen from Europe, Africa, and Asia.

Nevertheless, a number of the Americas will have the ability to see the tail finish of the eclipse because the Moon rises. By that stage, the eclipse can be in its penumbral stage. Meaning the umbra will now not be solid upon the Moon, however the outer a part of Earth’s shadow — the penumbra — can be. Put one other manner, in the event you had been standing on the Moon in Earth’s penumbra, you’ll see Earth partially eclipsing the Solar.

In a penumbral eclipse, the Moon’s reddish tint is extra delicate than in a total lunar eclipse. And even in the event you stay in Europe, Africa, or Asia, at this partial eclipse’s most, the umbra will cowl simply over 12 % of the lunar disk. However that’s a part of the intrigue of lunar eclipse watching — discovering out simply what you see, and the way dim and pink you understand the Moon to be.
