·What is the function of a Space Telescope? Let's take Hubble space telescope as an example.

NASA launched Hubble in 1990. Hubble is as long as a large school bus. It weighs as much as two adult elephants. Hubble travels around Earth at about 5 miles per second. That is as fast as driving a car from the East Coast of the United States to the West Coast in 10 minutes. Hubble faces toward space. It takes pictures of planets, stars and galaxies. It has seen stars born and die. It has seen galaxies that are trillions of miles away. Scientists have learned a lot about space from Hubble pictures. The pictures are beautiful to look at too.

What Makes Hubble Different From Telescopes on Earth?

The mixture of gases that surround a planet is called its atmosphere. Earth's atmosphere changes and blocks some of the light that comes from space. Hubble flies around, or orbits, high above Earth and its atmosphere. So, Hubble can see space better than telescopes on Earth can. Hubble is not the kind of telescope that you look through with your eye.  Hubble uses a digital camera. It takes pictures like a cell phone. Then Hubble uses radio waves to send the pictures through the air back to Earth.

Where Did the Name Hubble Come From?

Hubble is named after Edwin P. Hubble. He was an astronomer. An astronomer is a scientist who studies the planets, stars and space. Edwin P. Hubble made important discoveries about the universe in the early 1900s.                                                          

What Is the Future for Hubble?

In 2009, astronauts flew to Hubble on the space shuttle. This was the fifth time astronauts went to fix Hubble. They put new parts and cameras in the telescope. So, it is working very well. Hubble will not be fixed again. In 2020, Hubble turned 30 years old. It still takes beautiful pictures of objects in space.

 

1. Why NASA send Hubble into space rather than use telescope on Earth?

2. How did Hubble get its name?
