What is the Hubble?

Hubble is a telescope that orbits Earth. It was launched in 1990, 20 years ago. It also has high tech instruments that send data and images back to scientists on Earth to study.

How does the Hubble See?
Light enters an opening in the Hubble and travels through the chamber to a primary concave mirror. Light bounces off the mirror to a secondary convex mirror, and back again through a hole to instruments. The instruments send the signals to a satellite in space.

How Do Scientists See Images from Hubble?

Signals are sent from the Hubble to a relay satellite. The satellite sends those signals to Space Centers on Earth. Two of the centers are in New Mexico and Maryland. Scientists then see the images on their computers.
One of the images Hubble has sent is light from galaxies whose light has travelled 10 billion years to reach Earth.

Why Hubble is the Greatest Invention in Space Exploration

Hubble is one of NASA's most successful and long-lasting science missions. Unlike any other telescope, it has beamed hundreds of thousands of images back to Earth, and is helping astronomers to figure out the age of the universe, the identity of quasars, and the existence of dark energy. It is also helping scientists tell how fast the Universe is expanding.
The atmosphere can block and distort light that comes to us from outer space. Hubble is outside the atmosphere and can see much better than land telescopes. It can see infrared and ultraviolet lights as well.
No scientific instruments have been able to accomplish as much as the Hubble Telescope. It is the most successful and longest lasting space missions.
