What you will see
The illuminated part of the lunar disk matches the current phase; relief is most contrasted along the terminator.
Why it happens
The phase changes with the Sun–Earth–Moon geometry. We see a changing fraction of the Moon’s always half-lit surface.
How to watch
The phase is obvious to the naked eye. Binoculars reveal craters along the boundary between light and shadow.
Why it matters
A bright Moon dominates the night — great to watch, harder for faint stars.
