The Night Sky

If you stand outside on a clear, dark night, far away from any city lights, you may see a pale band of light stretching across the sky. The band of light is the Milky Way. The glow is from a huge number of stars.

Long ago, people could use only their eyes to study the sky. Over time, more powerful tools have allowed us to look farther and farther out into the universe. We’ve learned so much about space, but there is much more left to explore.

On dark and cloudless nights, people can view the stars.
