What is an eclipse?

There is a new moon, so the sun and the moon are aligned on the same plane. In that moment, the shadow of the earth on the moon is a perfect eclipse.

But there's a lunar eclipse and a solar eclipse. What's the difference?

The lunar eclipse happens when the moon blocks the sun during the night. The solar eclipse happens when the sun blocks the moon during the day.  In a lunar eclipse, the moon appears as an orange or brown disk. In a solar eclipse, the sun looks like a crescent.

There are many websites that tell you when they will happen, where to see them, and what to expect to see.  I'm happy to look for a list and share some examples.

If it's a lunar eclipse, you will see the moon fully in front of the sun.  If it's a solar eclipse, the moon is actually a few miles away.  To see the full effect, you will need to be very far from a large city with a lot of light.
