Accepted Answer

A galaxy is a huge collection of stars, dust, and gas all held together by gravity. Our galaxy is called the Milky Way and it has billions of stars!

Question 6

What is the Moon?

Accepted Answer

The Moon is a big rock in space that travels around Earth. It lights up at night because it reflects the Sun's light.

Question 7

Why is the sky blue during the day?

A telescope is a tool that makes faraway things in space look bigger and clearer. It helps us see things like stars and planets more closely.

Question 12

Why can't we see stars during the day?

Accepted Answer

We can't see stars during the day because the Sun's bright light makes the sky so bright that it hides the stars. But they're still up there shining!

Question 13

How do we know what stars are made of?

What are black holes?

Accepted Answer

Black holes are places in space where gravity is so strong that nothing, not even light, can escape. They are formed when massive stars collapse.

Question 17

Why do we have seasons?

Accepted Answer

We have seasons because Earth is tilted as it travels around the Sun. This tilt makes different parts of Earth get different amounts of sunlight throughout the year.

Question 18

Can we live on other planets?

Accepted Answer

Right now, Earth is the only planet where we know life can exist. Scientists are studying other planets to see if any might be able to support life in the future.

Question 19

Accepted Answer

A light-year is how far light can travel in one year. It's a way to measure really big distances in space, since space is so huge!

Question 20

Why do we need to study astronomy?

Accepted Answer

Studying astronomy helps us understand how the universe works. It answers big questions about where we come from and what else might be out there.
