As of April 25, the Moon is in its Waxing Gibbous phase, characterized by 63% illumination. This phase occurs just before the Full Moon, making it an exciting time for sky watchers.
Understanding the Waxing Gibbous Moon Phase
The Waxing Gibbous phase features a significant amount of the Moon’s surface illuminated by sunlight. Observers can easily view various lunar features with the naked eye, including:
- Mare Crisium
- Mare Tranquillitatis
- Mare Fecunditatis
For those equipped with binoculars, more details come into focus, including:
- Mare Nectaris
- Posidonius Crater

Upcoming Full Moon
The next Full Moon is scheduled for May 1. This will be the first of two Full Moons occurring in May, making it an intriguing month for lunar observations.
What are Moon Phases?
Moon phases result from the Moon’s orbit around Earth, which takes roughly 29.5 days to complete. Throughout this cycle, the Moon transitions through eight distinct phases:
- New Moon: The Moon is positioned between Earth and the Sun, making it invisible to observers.
- Waxing Crescent: A small sliver of light appears on the right side.
- First Quarter: Half of the Moon is illuminated on the right side, resembling a half-Moon.
- Waxing Gibbous: More than half is lit, yet it is not fully illuminated.
- Full Moon: The entire face of the Moon shines brightly.
- Waning Gibbous: The Moon begins to dim from the right side.
- Third Quarter: The left side of the Moon is now illuminated.
- Waning Crescent: A thin sliver of light persists on the left before returning to darkness.
For enthusiasts of astronomy, keeping track of these lunar phases can enhance the appreciation of our celestial companion.
