Today, February 13, 2025, the Moon is in its Waning Crescent phase, meaning it appears as a thin sliver of light in the sky. Approximately 17% of the Moon’s surface is illuminated. This phase occurs as the Moon approaches the New Moon, where it becomes invisible from Earth.
What You Can See Tonight
While the Moon is largely dark, observers with basic equipment can identify lunar features. Even without tools, the Aristarchus Plateau, a prominent crater spanning 25 miles in diameter, may be visible. Binoculars will reveal the Grimaldi Basin, while a telescope brings the Schiller Crater into view. These features are highlights of the diminishing light, offering a last glimpse before the next lunar cycle.
Moon Phases Explained
The Moon’s appearance changes predictably over approximately 29.5 days as it orbits Earth. This cycle results in eight distinct phases, determined by how much sunlight reflects off its surface. Each phase represents a different portion of the illuminated side visible from Earth.
- New Moon: The Moon is positioned between Earth and the Sun, making its visible side dark.
- Waxing Crescent: A thin sliver of light appears on the right side (in the Northern Hemisphere).
- First Quarter: Half of the Moon is lit on the right side.
- Waxing Gibbous: More than half is illuminated but not yet full.
- Full Moon: The entire face of the Moon is fully lit.
- Waning Gibbous: Light begins to fade on the right side.
- Third Quarter: The left side is half-lit.
- Waning Crescent: A final sliver of light remains before the cycle repeats.
Looking Ahead
The next Full Moon is scheduled for March 3, following a period of increasing illumination after the New Moon phase. The last Full Moon occurred on February 1, marking the completion of a previous lunar cycle.
Understanding these phases not only provides insight into celestial mechanics but also highlights the predictable yet captivating nature of our Moon.
This cycle has been observed and charted for millennia, serving as a fundamental calendar marker and continuing to fascinate observers today.
