The document discusses the history of understanding the solar system and galaxy. It explains that early humans thought the Earth was flat and the center of the universe, while Aristotle believed the Earth was the center. Copernicus proposed the Sun was the center, not Earth, which Galileo later confirmed using a telescope. The Space Age began in 1946 as the US and Russia raced to send the first person into space. Laika became the first living being in space in 1957 aboard Sputnik II. Modern technology now allows predicting weather and global communication.

3. This is a picture of the Sun in the Milky Way.
The Sun is the center of the Solar System.

the telescope and used it to confirm his idea that the Earth and other
planets revolved around the Sun.

8. In 1946 the Space Age began. USA and Russia
started a race to see which country could send
the first person into space.

9. 7. Basement
In November 3rd, 1957 Laika was the first living
being who traveled into space on the Sputnik II.

10. Now with technology we can predict the weather
and communicate with anybody around the
world.
