Did You Know: Space – What is space?
On cloudless nights when you look up at the dark sky, you can see space.
It stretches much farther than the eye can see and contains the moon, the sun, all the planets, as well as the Earth, and the stars. Space also contains many things that we haven’t yet discovered.
How do we explore space?
Telescopes
Telescopes help us see far into space.
They show us images of stars and galaxies too distant to travel to.
Robots
Robots can visit places in space that humans cannot yet reach. They help us understand these places.
People have been traveling into space since the 1960s. During their trips, they carry out experiments.
