Below, check out a visualization of what the Moon looked like during a lunar eclipse on May 26, 2021!
What’s the difference between a lunar eclipse and a solar eclipse?
A solar eclipse happens when the Moon gets in the way of the Sun’s light and casts its shadow on Earth. That means during the day, the Moon moves over the Sun and it gets dark. Isn’t it strange that it gets dark in the middle of the day?
This total eclipse happens about every year and a half somewhere on Earth. A partial eclipse, when the Moon doesn’t completely cover the Sun, happens at least twice a year somewhere on Earth.
But not everyone experiences every solar eclipse. Getting a chance to see a total solar eclipse is rare. The Moon’s shadow on Earth isn’t very big, so only a small portion of places on Earth will see it. You have to be on the sunny side of the planet when it happens. You also have to be in the path of the Moon’s shadow.
On average, the same spot on Earth only gets to see a solar eclipse for a few minutes about every 375 years!
Never look directly at the Sun, even for a second! It will damage your eyesight forever!
To view a solar eclipse, use special solar viewing glasses. Get them from a camera store or online.
SUNGLASSES DO NOT WORK, EVEN IF YOU STACK MANY OF THEM TOGETHER.
During a lunar eclipse, Earth gets in the way of the Sun’s light hitting the Moon. That means that during the night, a full moon fades away as Earth’s shadow covers it up.
The Moon can also look reddish because Earth’s atmosphere absorbs the other colors while it bends some sunlight toward the Moon. Sunlight bending through the atmosphere and absorbing other colors is also why sunsets are orange and red.
During a total lunar eclipse, the Moon is shining from all the sunrises and sunsets occurring on Earth!
Why don’t we have a lunar eclipse every month?
You might be wondering why we don’t have a lunar eclipse every month as the Moon orbits Earth. It’s true that the Moon goes around Earth every month, but it doesn’t always get in Earth’s shadow. The Moon’s path around Earth is tilted compared to Earth’s orbit around the Sun. The Moon can be behind Earth but still get hit by light from the Sun.
Because they don’t happen every month, a lunar eclipse is a special event. Unlike solar eclipses, lots of people get to see each lunar eclipse. If you live on the nighttime half of Earth when the eclipse happens, you’ll be able to see it.
Remembering the Difference
It’s easy to get these two types of eclipses mixed up. An easy way to remember the difference is in the name. The name tells you what gets darker when the eclipse happens. In a solar eclipse, the Sun gets darker. In a lunar eclipse, the Moon gets darker.
