Here's Why You Can See the Moon During the Day

When thinking about the Moon, many find themselves wondering what it was like to walk on it as Neil Armstrong did. They also find themselves wondering why the Moon is often still visible during the day even though it's always associated with night. It turns out that there's a fairly simple explanation behind it.

Keen sky observers may have noticed the Moon doesn't follow a strict schedule because sometimes it makes an early appearance before nightfall. The Moon, like stars and planets, is always present, but its daytime visibility is often overshadowed by the radiant Sun and a bright daytime sky. The Moon doesn't make its own light, relying on illumination from the sun that reflects off of its surface, and this happens both during the day and at night. When it goes through waxing and waning phases, it's so close to Earth that it's often able to "shine" brighter than the sky, which is why we can see it.

This was confirmed by Sarah Noble, a planetary geologist and NASA scientist. In a NASA video, she highlights that the Moon's brightness graces both parts of the day when it's in the "right part" of the sky. When it isn't, it's either harder to see or completely invisible to the naked eye.
