Why is the Hubble space Telescope better than telescopes on Earth?
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. Then Hubble uses radio waves to send the pictures through the air back to Earth.
Can Hubble be upgraded?
Fortunately, Hubble was the first telescope designed to be visited in space by astronauts to perform repairs, replace parts and update its technology with new instruments.
Is James Webb telescope launched?

Why is the Hubble telescope the most powerful?
The Hubble telescope provides four key advantages over most other optical astronomical facilities: unprecedented angular resolution over a large field, spectral coverage from the near infrared to the far ultraviolet, an extremely dark sky, and highly stable images that enable precision photometry.
How much would Hubble weigh here on Earth?
The total archive is currently over 150 TB in size. 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.
Will there be a new Hubble telescope?
It is planned to succeed the Hubble Space Telescope as NASA’s flagship astrophysics mission. JWST is scheduled to be launched no earlier than Friday 24 December 2021 during Ariane flight VA256….James Webb Space Telescope.

What does NASA know about the Hubble telescope?
This article is part of the NASA Knows (Grades 5-8) series. The Hubble Space Telescope is a large telescope in space. It was launched into orbit by space shuttle Discovery on April 24, 1990. Hubble orbits about 547 kilometers (340 miles) above Earth.
Will the Hubble telescope ever be repaired or upgraded?
The telescope will not be repaired or upgraded again, but it is still working. Meanwhile, NASA and its international partners are preparing the James Webb Space Telescope. The Webb is an infrared telescope that will be larger than Hubble and will be able to see through clouds and dust in space.
How many miles above the Earth does Hubble orbit?
Hubble orbits about 350 miles (560 kilometers) above Earth’s surface. The spacecraft completes 15 orbits per day – approximately one every 95 minutes. 1. Wide Field Camera 3 ( WFC3)
What are the advantages of a Space Telescope?
In 1946, Lyman Spitzer, a professor and researcher at Yale University, argued that a space telescope would offer great advantages over ground-based observatories. His paper, entitled Astronomical Advantages of an Extra-Terrestrial Observatory, explained that the Earth’s atmosphere blurs and distorts light coming from stars.
