that the earth is a sphere astronomers observed that the earth's shadow on the

They also observed that on the horizon, that when a ship appeared, the top was visible

00:00:48,469 --> 00:00:51,429
before the rest of the ship.

00:00:51,429 --> 00:00:58,429
Seventeenth Century The telescope was invented in the 17th century.

8
00:00:58,429 --> 00:01:05,090
Telescopes use lenses to help us see objects that are way far away.

9
00:01:05,090 --> 00:01:12,349
discovered planets like Uranus and Neptune using telescopes. Today we have

10
00:01:12,349 --> 00:01:23,370
huge powerful telescopes that can look deep into outer space. 20th century 1961

00:01:23,370 --> 00:01:32,230
Yuri Gargan was the first person to go into space. He was there for 108 minutes.

1990. The Hubble telescope was launched into space in 1990. The Hubble has helped scientists

14
00:01:49,450 --> 00:01:55,590
to discover more about other galaxies and our universe while it orbits the earth.

Since 2000, astronauts from all over the world have lived on the International Space Station.

18
00:02:14,590 --> 00:02:18,590
The space station orbits the Earth every 12 minutes.

19
00:02:18,590 --> 00:02:24,849
Astronauts live in the space station and study biology, physics, and astronomy there.
