Does the Moon Glow?

Does the Moon Glow?

Ever notice how bright the night sky is when there’s a full moon and clear sky? Ever wonder what why you can't see the moon even when it's a clearn sky? How does the moon "glow?"

The moon does not glow, it actually eflects light from the sun. Out in space, sunlight falls upon the moon at various angles, producing the various phases of the moon.

Like the earth, the moon is a sphere which is always half illuminated by the sun. As the moon orbits the earth, we see more or less of the illuminated side. Throughout a lunar month, the cycle from illuminated, to partially and completely illuminated can be apparent to the viewer. These visual times are what we refer to as phases of the moon.

However, during a new moon, the moon’s unilluminated side is facing the earth. As such we cannot view the moon, unless there is a solar eclipse.

If you notice a hole in the upper left-hand corner of your Farmers' Almanac, don't return it to the store! That hole isn't a defect; it's a part of history. Starting with the first edition of the Farmers' Almanac in 1818, readers used to nail holes into the corners to hang it up in their homes, barns, and outhouses (to provide both reading material and toilet paper). In 1910, the Almanac's publishers began pre-drilling holes in the corners to make it even easier for readers to keep all of that invaluable information (and paper) handy.
