When the Moon is full, for example, it tends to be dazzlingly bright and one-dimensional.
Observing the Moon is one of the easiest ways to get started with astronomy. You can track the lunar cycle, and use binoculars or a telescope to see how your view of it changes. When the Moon is full, for example, it tends to be dazzlingly bright and one-dimensional. In contrast, when the Moon is a crescent shape (around first or last quarter phase) you’ll get a more dramatic view of its craters since they’ll be well-defined by shadows.
