National Dark-Sky Week

National Dark-Sky Week is a time when people try to make it really dark outside at night so they can see the stars better. The sky is usually really bright at night because of things like streetlights, car lights, and other lights that people use. National Dark-Sky Week is a special time when people try to turn off or dim those lights so that they can see the stars better.

When the sky is really dark, we can see a lot of really pretty things in the sky. These are things like stars, planets, and even things called galaxies. Galaxies are like groups of stars that are really far away from us. They are really pretty, and we can learn a lot about them by studying them.

National Dark-Sky Week is also important because it helps us take care of the environment. When we turn off the lights at night, we save a lot of energy. This is good for the environment because it means we are using less electricity. Less electricity means less pollution, which is better for the planet.

During National Dark-Sky Week, people can do lots of fun things to enjoy the stars. Sometimes they have star parties, where people get together to look at the stars. They might also have special telescopes that can help them see things in the sky more clearly.

In summary, National Dark-Sky Week is a special time when people try to make it really dark outside at night so they can see the stars better. It is also important because it helps us take care of the environment by using less energy.
