There are many galaxies besides the Milky Way Galaxy we call home. There are so many, we can’t even count them all yet! The Hubble Space Telescope looked at a small patch of space for 12 days and found 10,000 galaxies, of all sizes, shapes, and colors. Some scientists think there could be as many as one hundred billion galaxies in the universe.

The sun sends lots of energy toward us all the time. There are a few different kinds of energy. There is infrared radiation, which is heat. There is visible light, which is what our eyes can see. There is also ultraviolet light. We can’t see ultraviolet with our eyes, but it’s there. And it can burn our skin.

Earth and the moon are very good friends, but they’re not as close as they seem. They’re actually really far apart. The moon is an average of 238,855 miles (384,400 km) away. How far away is that? That’s 30 Earths. And the moon is moving very slowly away from us. It gets about 1 inch farther away each year. But don’t worry. They’ll still be friends for a very long time!

We finally got to visit Pluto, Charon, and the Kuiper Belt! On January 19, 2006, NASA launched a robot spacecraft on the long journey. This mission is called New Horizons. The spacecraft arrived at Pluto in July 2015, and it will continue to study other objects in the Kuiper Belt from about 2018 to 2022.
