Which of the following statements accurately describe the phases of a lunar eclipse? Select all that apply.

A lunar eclipse begins when the Moon first slips into Earth’s penumbral shadow, causing a subtle dimming that lasts until the Moon starts to touch the darker umbra. The next phase is the partial eclipse, when only part of the Moon enters the umbra and a darker crescent or “bite” appears. If the alignment is perfect, the Moon then becomes fully engulfed in the umbra, producing a total eclipse where the Moon turns a reddish color. Finally the Moon exits the umbra and returns to the penumbra before emerging into full daylight. These four stages—penumbral, partial, total, and exit—are the standard phases of a lunar eclipse.
