Discover the Waning Crescent Moon on July 22, 2025

The moon today, July 22, 2025, is in the Waning Crescent phase, which means it is nearly invisible from Earth, with only 7% of its surface visible. This phase marks day 27 of the lunar cycle, which spans approximately 29.5 days according to NASA. Observers looking to catch a glimpse of the moon tonight will find it challenging, as much of its surface is obscured.

Understanding the Lunar Phases

The lunar phases result from the varying angles of sunlight hitting the moon as it orbits our planet. During the Waning Crescent phase, the moon lies between Earth and the sun, leaving its illuminated side hidden from view. To see any details, such as the renowned Grimaldi Basin, enthusiasts will need binoculars or a telescope. The Grimaldi Basin is notable for its size, with an outer wall comparable to that of the Grand Canyon.

Tonight’s viewing conditions may not be ideal for casual observers, as the lunar surface lacks significant illumination. For those determined to explore the moon’s features, telescopes can provide a rewarding experience, allowing for a close-up view of the Grimaldi Basin’s unique characteristics.

The next full moon will occur on August 9, 2025, following the last full moon, which took place on July 10, 2025. The cycle of moon phases is a fascinating natural phenomenon, capturing the interest of both casual stargazers and serious astronomers alike.

The Eight Phases of the Moon

The lunar cycle comprises eight distinct phases, each representing a different stage in the moon’s visibility. These phases are:

• New Moon: The moon is positioned between Earth and the sun, resulting in a dark sky.
• Waxing Crescent: A small sliver of light begins to appear on the right side (in the Northern Hemisphere).
• First Quarter: Half of the moon is illuminated, resembling a half-moon.
• Waxing Gibbous: More than half of the moon is lit but not quite full.
• Full Moon: The entire face of the moon is illuminated, fully visible to observers.
• Waning Gibbous: The moon starts to lose light on the right side.
• Last Quarter: Again, half of the moon is visible, but now the left side is lit.
• Waning Crescent: A thin sliver of light remains on the left before it goes dark once more.

This cyclical pattern not only affects how we view the moon but has also played a significant role in various cultural and scientific contexts throughout history. Understanding these phases can enhance the experience of gazing at the night sky.
