When can a total lunar eclipse be seen?

At the new moon
At the full moon
When it is a first quarter moon

See the answer

At the full moon

A total lunar eclipse occurs when the Sun, Earth, and Moon align in a straight line, and the Moon is completely within Earth’s shadow. At this time, the Moon is always full. Try thinking about it by focusing on the relative positions of the Sun, Earth, and Moon.

An omen of ominous events such as war or disasters

People in ancient times regarded a total lunar eclipse—when the Moon suddenly turns red—as a mysterious and ominous phenomenon, seeing it as a harbinger of misfortune such as war, disasters, and epidemics. Before it was scientifically understood, many cultures feared lunar eclipses as warnings of impending calamities like disasters and war.

From the shape of Earth’s shadow cast on the Moon during a lunar eclipse, what would the ancient Greeks have inferred?

The Earth is flat.
The Earth is triangular.
The Earth is a sphere.

See the answer

The Earth is a sphere.

Please focus on the shape of the shadow as you think about it. In a total lunar eclipse, the Earth’s shadow on the Moon is always round, which led the ancient Greeks to infer that the Earth is a sphere. This is because the shadow of a flat object is not necessarily round.

Which of lunar eclipses and solar eclipses can be observed over a wider area on Earth?

lunar eclipse
solar eclipse
Both cover the same scope.

See the answer

lunar eclipse

Let's consider the sizes of the shadows. A lunar eclipse can be observed from more than half of the Earth, whereas a solar eclipse—especially a total solar eclipse—can only be seen from a limited, narrow, band-shaped region. This is because, in a lunar eclipse, the Moon enters the Earth's shadow, allowing it to be visible from almost the entire nighttime side of the Earth.

In theory, when does a total lunar eclipse last the longest—at which part of Earth’s shadow does the Moon pass?

the central part of the umbra
edge of the umbra
the middle of the umbra

See the answer

the central part of the umbra

If the Moon passes through the central part of the umbra, it remains within the umbra for the longest distance, so the total lunar eclipse lasts the longest. If it passes near the edge, the distance it travels through the shadow is shorter, and the totality is shorter. During a total lunar eclipse, the Moon passes through Earth’s umbra.
