Step 1: What’s Inside the Universe?

In the universe, there are many different things:

• Stars: These are huge balls of hot gas that light up the night sky. The Sun is a star, and it gives us light and warmth.

• Galaxies: A galaxy is a massive group of stars and planets. Our galaxy is called the Milky Way!
• Asteroids and Comets: Asteroids are rocky and can be found in space, while comets are icy and have beautiful tails when they come near the Sun.

Step 2: How Big is the Universe?

The universe is incredibly big! It has no end, which means it goes on and on forever! Scientists say the universe is so big that if you tried to count all the stars, it would take a very, very long time.

Step 3: How Old is the Universe?

The universe is about 13.8 billion years old. That’s older than your grandparents, great-grandparents, and even great-great-grandparents! It started with a big explosion called the Big Bang, which started everything we see today!

Step 4: Exploring the Universe

People use telescopes to look at the stars and planets from Earth. There are also robots and spacecraft, like the Mars Rover, that travel to other planets to learn more!

Step 5: Fun Facts!

• Did you know that some stars are so far away that their light takes millions of years to reach us?
• There are more stars in the universe than there are grains of sand on Earth!
