NASA explains the reason behind the moon's sporadic daytime visibility.


Like other stars and planets, the Moon is always present in the sky, but because of its brightness, it is usually invisible to the naked eye. Numerous thoughts conjure up our ideal state of mind when we think of the Moon.

Whether it's Ghalib, Mir, or Sahir Ludhianvi's seductive analogy, or Neil Armstrong's historic walk.

The Moon can also be seen in literary works such as P.B. Shelley's “To the Moon,” in which the Moon is a witness to thoughts and feelings, or William Shakespeare’s “A Midsummer Night’s Dream,” which illustrates the erratic nature of love.

There is a convincing scientific argument for seeing the Moon during the day, aside from the romantic notion of a lover's eye that can eternally observe the Moon, the beloved.

There are other effects of the moon cycle besides light availability after dark. For instance, the Moon's alignment with respect to the Earth and the Sun causes solar eclipses.

Similar to the Sun's blaze, the Moon is ever-present but typically obscured from view by the bright sky, just like the stars and planets. Even so, it continues to be a rare sight throughout the solar system as daybreak approaches.

The Moon does not generate its own light; instead, it is illuminated by the Sun's surface glow. There are four phases to the Moon's orbit; during its waxing and waning phases, the Moon appears closer to Earth and outshines the daytime sky.

As Sarah Noble, a planetary geologist and NASA scientist, put it, the Moon is "almost as much in the daytime sky as the night."

Noble clarified that the Moon's visibility during the day is dependent on its orbital pattern, phase, and proximity to Earth in a NASA video that was posted to YouTube. As long as the Moon is in the correct position in the sky, weather and cloud cover can also affect how visible it is during the day.

Noble continued, "The reason the Moon's whole face is visible when it reflects sunlight is because the Moon is in opposition to the Sun in the sky during a full moon. Only on that one day of the month does the Moon rise in tandem with the Sun's lowering phase due to Earth's rotation.

When a full Moon is approaching, you can see the nearly full Moon rising in the eastern sky before dusk. Additionally, in the days following a full Moon, you can observe the Moon setting after the Sun has risen in the western sky.

he Moon is visible during the day due to the way sunlight interacts with its surface and the Earth's atmosphere. The Moon does not emit its own light; instead, it reflects sunlight. The amount of sunlight reflected by the Moon depends on its position relative to the Sun and Earth.

Here's how it works:

  1. Sunlight Reflection: The Moon reflects sunlight, and this reflected light reaches Earth. When the Sun is shining on the side of the Moon facing us, we see a fully illuminated, bright Moon.

  2. Earth's Atmosphere: Earth's atmosphere plays a crucial role. Even during the day, our atmosphere scatters sunlight. This scattering is why we see the sky as blue. When the Moon is visible during the day, it's often against a blue sky. The scattered sunlight also illuminates the Moon, making it visible even though the Sun is still in the sky.

  3. Position of the Moon: The Moon orbits the Earth, and its position in the sky changes over time. Sometimes, it's on the opposite side of the Earth from the Sun, resulting in a full moon. At other times, it's closer to the Sun, leading to various phases like crescents or half-moons.

In summary, the Moon is visible during the day because it reflects sunlight, and when its position in its orbit aligns with the Sun and Earth in such a way that it's visible from our perspective on Earth, we can see it even against the backdrop of the daytime sky.
