The Moon

Our nearest neighbour, night by night

The Moon is the easiest thing in the sky to observe and the biggest obstacle to seeing everything else. Here’s where it is in its cycle, calculated for any date you choose.

Phase guide

When each phase is up, and what it costs you

Each day the Moon rises about 50 minutes later than the day before. That simple rhythm tells you when the sky will be dark.

Waxing Crescent Mid-morning West after sunset Good
First Quarter Around noon Evening, sets ~midnight Fair
Waxing Gibbous Afternoon Most of the night Poor
Full Moon Sunset All night Worst

Observing the Moon

Look at the edge, not the full face

The full Moon is dazzling but flat: sunlight hits it head-on and casts no shadows. The best views come along the terminator, the line between day and night, where low sunlight throws crater walls and mountains into sharp relief.

Around first quarter the terminator crosses the Moon’s most rugged regions, and it’s high in the sky at a comfortable evening hour.

  • Binoculars show the dark “seas” (maria) and the largest craters.
  • Earthshine: on a thin crescent, the “dark” part glows faintly with sunlight reflected off Earth.
  • Any small telescope reveals hundreds of craters; a moon filter takes the glare off.
  • Watch it move: the Moon shifts its own width against the stars about every hour.
