Why can the Hubble space Telescope see the universe 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.
What is one main difference between the Hubble and the James Webb Space Telescopes?
Webb’s primary mirror has a diameter of 6.5 metres. Hubble’s mirror was much smaller – 2.4 metres in diameter. So, Webb will have a larger field of view compared to the camera on Hubble. Webb also carries a large sun shield measuring about 22 metres by 12 metres – about the size of a tennis court.
Which of these is one reason that having the Hubble telescope in space is better than having a telescope on a mountaintop?
Which is one reason that having the Hubble telescope in space is better than having a telescope on a mountain top? Clouds do not block the view of the Hubble telescope. In which of the following technologies do satellites work together to aid in navigation? You just studied 20 terms!
What will happen to the Hubble telescope after this year?
The telescope completed 30 years in operation in April 2020 and could last until 2030–2040. One successor to the Hubble telescope is the James Webb Space Telescope (JWST), which is to be launched in December 2021.
Why does the Hubble telescope work better?
Earth’s atmosphere alters and blocks the light that comes from space. Hubble orbits above Earth’s atmosphere, which gives it a better view of the universe than telescopes have at ground level.
What gives Hubble excellent clarity?
In space, the clarity of Hubble’s images (defined by angular resolution) is limited by the size of its 2.4 metre mirror rather than atmospheric turbulence. Being in space gives Hubble incredible advantages compared to Earth-bound telescopes.
Why is WFIRST’s primary mirror smaller than Hubble?
To collect as much light as possible, telescopes need large primary mirrors. Since both WFIRST and Hubble have a primary mirror that is 2.4 meters (7.9 feet) across, they gather the same amount of light. While the same size, WFIRST’s mirror is only one-fourth the weight of Hubble’s thanks to advancements in technology.
Why is the Hubble telescope so good at viewing space?
Above the atmosphere the Hubble is able to produce very sharp and tightly focused images and therefore is able to see fainter, farther and more clearly than the 200 inch. How much life does the Hubble have on orbit?
What is the replacement for the Hubble telescope?
Webb often gets called the replacement for Hubble, but we prefer to call it a successor. Hubble’s science pushed us to look to longer wavelengths to “go beyond” what Hubble has already done. Comparison of the Carina Nebula in visible light (left) and infrared (right), both images by Hubble.
What is the difference between the Palomar and Hubble telescope?
Although the Palomar 200 inch has four times more light collecting area than Hubble, the Palomar telescope’s images are smeared out and distorted by the earth’s atmosphere. Above the atmosphere the Hubble is able to produce very sharp and tightly focused images and therefore is able to see fainter, farther and more clearly than the 200 inch.
