With many celestial events occurring every year, the night sky is one of the few places left where you can experience genuine awe and wonder. This weekend, you have the opportunity to view a spectacular lunar eclipse.
If you are in a part of the world that can see the moon on May 15, you will be able to view it with the naked eye. However, to get the most out of the event — and to document it — there are a few pieces of equipment, such as a telescope and a camera, you’ll want to have on hand.
Celestial events have cool names. “Lunar eclipse” sounds like something that happens on an immense scale. To be fair, since it involves the largest celestial body in our solar system, it does. However, when you look at it on the most basic level, an eclipse is just a shadow.
There are three items you need to create a lunar eclipse: the moon, a light source and an object that makes the shadow. The light source is the sun, and the object that makes the shadow is the earth. When the earth passes between the sun and the moon, and all three celestial bodies are in a straight line, it casts a shadow on the moon. This is called a lunar eclipse.
A lunar eclipse is also known as a blood moon. This is because the moon has a red hue during a lunar eclipse. Oddly enough, red is the color of the earth's shadow when it falls on the moon.
You might wonder how a shadow can be red and not black. The earth doesn’t block all the light from reaching the moon. Instead, the light bends (or refracts) around the earth, thanks to its atmosphere. While the light of shorter wavelengths, such as violet, blue and green, is scattered during this phenomenon, the light of longer wavelengths, including red, orange and yellow, makes it through to fall on the moon. This gives the moon its red coloring during a lunar eclipse. Consequently, the same thing happens at sunrise and sunset as the light bends through the earth’s atmosphere.
Unlike a solar eclipse, which could permanently damage your retinas in a very brief period, it is safe to view a lunar eclipse. You can watch a lunar eclipse because you are not looking at the sun. The red light of a lunar eclipse is reflected light. You have no more risk of damaging your eyes from watching a lunar eclipse than you would by looking at the full moon.
Because the moon’s orbital plane is tilted roughly 5 degrees, the sun, earth and moon only line up about two times each year. But this doesn’t necessarily mean you can see two lunar eclipses every year. If you happen to be on the right part of the planet when this alignment happens, you can view the lunar eclipse. If you are on the wrong side of the earth, you will have to wait until an eclipse happens in your region to be able to view it. The upcoming lunar eclipse will be visible to most of North America, all of South America, all of Central and Western Europe, and most of Africa. This means roughly 2.7 billion people can watch the lunar eclipse.
The lunar eclipse takes place at exactly the same moment everywhere. Because of different time zones, however, the local time for viewing the lunar eclipse will be different.
