Today’s Moon Phase: April 23, 2026 Lunar Appearance Explained

As we approach the First Quarter Moon, the lunar surface is becoming increasingly illuminated. Each evening, the Moon grows brighter, culminating in the Full Moon, after which its brightness will begin to wane. This fascinating cycle of illumination is a captivating aspect of lunar observation.

What is today’s Moon phase that you can observe?

On Thursday, April 23, the current Moon phase is classified as a Waxing Crescent. Tonight, approximately 41% of the lunar surface will be illuminated, as detailed in NASA’s Daily Moon Guide. This phase presents an excellent opportunity for amateur astronomers and enthusiasts alike to enjoy the beauty of the Moon.

With the naked eye, you can spot the prominent Mare Serenitatis, Mare Tranquillitatis, and Mare Fecunditatis on the Moon’s surface. If you are equipped with binoculars, you can also observe Mare Nectaris, along with the Endymion and Posidonius Craters, which become visible as you gaze from the Moon’s midsection toward its upper regions. For those using a telescope, the view expands even further to reveal the historic landing sites of Apollo 11 and Apollo 17, as well as the intriguing Rupes Altai.

When is the next Full Moon that we can look forward to?

The upcoming Full Moon is forecasted to occur on May 1, marking the first of two full moons within the month of May. This event is often highly anticipated by both stargazers and photographers, as the Full Moon provides a spectacular display in the night sky.

What are the different Moon phases that define its cycle?

According to NASA, the Moon completes a full orbit around the Earth approximately every 29.5 days, during which it transitions through eight distinct stages known as lunar phases. Despite always showing the same face to Earth, the illuminated portion of the Moon changes as it travels along its orbital path, resulting in the familiar cycle of full, half, and crescent shapes. The eight lunar phases include:

New Moon – During this phase, the Moon is positioned between the Earth and the Sun, rendering its visible side completely dark and essentially invisible to observers.

Waxing Crescent – A small sliver of light begins to appear on the right side of the Moon, marking the initial stages of illumination in the Northern Hemisphere.

First Quarter – At this point, half of the Moon is illuminated on the right side, presenting the familiar shape known as the half-Moon.

Waxing Gibbous – More than half of the lunar surface is now lit, but it has not yet reached full brightness.

Full Moon – During this phase, the entire face of the Moon is illuminated, offering a breathtaking view of its surface features.

Waning Gibbous – The illumination begins to decrease on the right side, indicating that the Moon is transitioning away from its full phase in the Northern Hemisphere.

Third Quarter (or Last Quarter) – Another half-Moon phase occurs, but this time the left side is illuminated instead.

Waning Crescent – A thin sliver of light remains visible on the left side before the Moon transitions back to darkness.
