If you ever look up at a full moon at night, you will see a large halo of light around it. This halo is not an indication of poor eyesight, but a result of ice particles or ice crystals. According to experts from Columbia University, tiny ice particles scatter the moonlight. These are mainly pure ice clouds that exist in the upper atmosphere 31 miles above the Earth’s surface. In simple words, the light from the moon reaches our eyes through ice particles and that is why we see the glowing halo around the moon.
