Moon, the beautiful silver disc hanging in the night sky, always gives me a sense of mutability and mystery. Have you ever looked up the sky and have a careful observation of the Moon? Have you ever had this question: “Why does the Moon look different every night? Do these changes follow particular patterns?” With such questions, I am ready to explore the science behind it and learn the interesting knowledge about Moon Phases.
According to the Wikipedia, the lunar phase or phase of the moon is the shape of the illuminated portion of the Moon as seen by an observer on Earth. The lunar phases change cyclically as the Moon orbits the Earth, according to the changing positions of the Moon and Sun relative to the Earth.
One easy way to understand the moon phase is through an easy and interesting Moon Phase Demonstration Activity! Simply imagine a light source (a lamp) as the Sun, a ball that you will hold in your hand as the Moon and yourself as a observer standing on Earth. Hold the Moon ball out level with you head and try turning you body according to the position of the lamp. Then you will see the changes in the illuminated portion of the ball and get to know how will each moon phase happen.
At the time I am editing this blog post, the Moon is in a Waning Gibbous phase, which is the first phase after the Full Moon occurs. If you are curious about what phase the moon is in at the time you read this blog, exploring Today’s Moon Phase at the Moongiant Website.
It is very exciting to find out that we just had a Full Moon on Feb 11th, 2017, which is the day before yesterday!
