Skywatchers are in for a treat as the Moon approaches its fullest phase. As of Sunday, March 29, 2026, the Moon is in the Waxing Gibbous phase, meaning more than half of its surface is illuminated. This presents an excellent opportunity for observing lunar features, even without specialized equipment.
The current lunar phase offers a beautiful view, with 85% of the Moon lit up tonight, according to NASA’s Daily Moon Guide. This phase is ideal for spotting the prominent dark plains, known as maria, that mark ancient volcanic activity on the lunar surface. Understanding the phases of the Moon provides insight into our celestial neighbor and its relationship with Earth.
For those eager to witness the next full lunar spectacle, mark your calendars. The next Full Moon in North America is predicted to occur on April 1, 2026.
What You Can See Tonight
Even without telescopes or binoculars, observers can readily identify the Serenitatis, Imbrium, and Vaporum maria – large, dark, basaltic plains formed by ancient volcanic eruptions. These “seas” are easily visible as darker patches against the brighter highlands. With a pair of binoculars, the Mare Frigoris, Archimedes Crater, and the Clavius Crater become visible, offering a closer look at the Moon’s textured surface. For those with access to a telescope, the Caucasus Mountains, the Apollo 12 landing site, and the Linne Crater offer even more detailed views.
Understanding Lunar Phases
The Moon doesn’t generate its own light; we see it because it reflects sunlight. As the Moon orbits Earth – completing one orbit in roughly 29.5 days – the amount of illuminated surface visible to us changes, creating the lunar phases. NASA explains that even as the same side of the Moon always faces Earth, the varying angles of sunlight create the illusion of a changing shape.
These eight distinct phases are:
- New Moon: The Moon is positioned between Earth and the Sun, rendering the side facing us dark and invisible.
- Waxing Crescent: A sliver of light appears on the right side (in the Northern Hemisphere), gradually increasing in size.
- First Quarter: Half of the Moon is illuminated on the right side, resembling a half-circle.
- Waxing Gibbous: More than half of the Moon is lit, but it’s not yet full.
- Full Moon: The entire face of the Moon is illuminated, appearing as a bright, complete circle.
- Waning Gibbous: The illuminated portion begins to decrease on the right side.
- Third Quarter (or Last Quarter): Half of the Moon is lit, but on the left side.
- Waning Crescent: A thin sliver of light remains on the left side before disappearing again.
Looking Ahead
The approaching Full Moon on April 1st will be a significant event for lunar observers. As the Moon continues its cycle, it will offer different viewing opportunities, each revealing unique aspects of its surface. Continued observation and study of the Moon contribute to our understanding of the solar system and the Earth-Moon relationship. The next confirmed checkpoint will be the observation of the April 1st Full Moon and subsequent analysis of its features.
