What is special about the Hubble Space Telescope?
It is a very special telescope which orbits far above the Earth. Hubble allows us to see objects more clearly because it is above the clouds in Earth’s atmosphere. These clouds block the view of the Earth-based telescopes which scientists have used for many years.
What are 3 discoveries of Hubble?
What has Hubble found?
- Helped pin down the age for the universe now known to be 13.8 billion years, roughly three times the age of Earth.
- Discovered two moons of Pluto, Nix and Hydra.
- Helped determine the rate at which the universe is expanding.
How heavy is the Hubble telescope?
Hubble weighed about 24,000 pounds at launch but if returned to Earth today would weigh about 27,000 pounds — on the order of two full-grown African elephants. Hubble’s primary mirror is 2.4 meters (7 feet, 10.5 inches) across.
How big is Hubble telescope?
43.5 ft.
Hubble is 13.2 metres (43.5 ft.) long and its maximum diameter is 4.2 metres (14 ft.) It is about the size of a large truck.
How did Hubble get its name?
Where did the Hubble get its name from? Hubble was named in honor of the great American astronomer, Edwin P. Hubble. He was born in 1889 in Missouri and studied law at the University of Chicago and at Oxford University in England.

Who built the Hubble telescope?
NASA’s immense Hubble space telescope launched on April 24, 1990. Lockheed Martin built the complex spacecraft at its facility in Sunnyvale, California. The company’s photos give a behind-the-scene look at Hubble’s assembly before launch.

How fast does the Hubble telescope travel?
17,500 miles
Hubble in Earth orbit after deployment. Hubble travels at a speed of 17,500 miles/27,300 kilometers per hour as it orbits Earth. It takes approximately 95 minutes to complete one trip around Earth. Hubble orbits Earth about 340 miles/547 kilometers above its surface.
What are some interesting facts about the Hubble telescope?
Hubble, the observatory, is the first major optical telescope to be placed in space, the ultimate mountaintop. Above the distortion of the atmosphere, far far above rain clouds and light pollution, Hubble has an unobstructed view of the universe. Scientists have used Hubble to observe the most distant stars and galaxies as well as the planets
What was the initial problem with the Hubble Space Telescope?
The most serious and notorious of these was an optical defect called spherical aberration, which was caused by the malfunction of a measuring device used during the polishing of the mirror. As a result, Hubble could not achieve the best possible image quality, although still outperforming ground-based telescopes in many ways.
What does the Hubble Space Telescope really see?
wavelength. the james webb space telescope carries four scientific instruments and observes primarily in the infrared range that provide coverage from 0.6 to 28 microns. the instruments on hubble see mainly in the ultraviolet and visible part of the spectrum that is why it.
What makes the Hubble Space Telescope so special?
What makes Hubble so special? It is a very special telescope which orbits far above the Earth. Hubble allows us to see objects more clearly because it is above the clouds in Earth’s atmosphere. Hubble is not only a powerful telescope, but it also carries cameras which allow scientists on Earth to see objects billions of light-years away.
