What is the advantage of using space telescopes over ground telescopes?
Space-based telescopes like Hubble get a much clearer view of the universe than most of their ground-based counterparts. They’re also able to detect frequencies and wavelengths across the entire electromagnetic spectrum.
What are three advantages of using a space based telescope such as Hubble over land based telescopes?
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.
What are the disadvantages of a ground-based telescope?
Despite the convenience of ground telescopes, they do feature a few drawbacks that space telescopes don’t have.
- Lower Cost. Ground-based telescopes cost about 10 to 20 times less than a comparable space telescope.
- Maintenance Issues.
- Site Requirements.
- Image Quality.
- Deficient Data.
Are there any more space telescopes in the works?
You’ll be glad to know there are even more space telescopes in the works, a set of four powerful instruments in design right now, which will be part of the next Decadal Survey, and helping to answer the most fundamental questions about the cosmos. The James Webb Space Telescope inside a cleanroom at NASA’s Johnson Space Center in Houston.
What is the best alternative to James Webb Space Telescope?
The Origins Space Telescope will be a better version of James Webb. LUVOIR will be the true successor to the Hubble Space Telescope.
Is the Hubble Space Telescope getting old?
But let’s face it, Hubble is getting old, and it probably won’t be with us for too much longer. NASA’s James Webb Space Telescope is in the final stages of testing, and WFIRST is waiting in the wings.
What is the size of the Webb telescope mirror?
Webb will have an approximately 6.5 meter diameter primary mirror, which would give it a significantly larger collecting area than the mirrors available on the current generation of space telescopes.
