Why are space telescopes useful?
The main reason we put telescopes into space is to get around the Earth’s atmosphere so that we can get a clearer view of the planets, stars, and galaxies that we are studying. Our atmosphere acts like a protective blanket letting only some light through while blocking others. Most of the time this is a good thing.
What are two advantages that the Hubble space Telescope has over ground-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 advantages does the Hubble or James Webb space Telescope have over ground-based 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 is unique special about space telescopes?
Though Hubble’s mirror is much smaller than those found in the largest ground-based observatories, the telescope’s unique position above Earth’s atmosphere gives it incredible clarity. As the telescope orbits Earth, its mirror gathers light from the cosmos, collecting images and data.
What are the advantages and disadvantages of placing telescopes in space?
In space, however, telescopes are able to geta clearer shot of everything from exploding stars to other galaxies. Another disadvantage for ground-basedtelescopes is that the Earth’s atmosphere absorbs much of the infrared andultraviolet light that passes through it. Space telescopes can detect thesewaves.
What are space-based telescopes?
Space-based telescopes allow for observations outside the Earth’s atmosphere and light pollution. Probably the most-famous of the space-based telescopes is the Hubble Space Telescope (HST). NASA plans to launch the Webb Space Telescope in 2018. There are a number of planetary and Solar System probes.
What are the pros and cons of space-based telescopes?
What is the main advantage of the Hubble Space Telescope quizlet?
The main advantage of using the Hubble Space Telescope is the increased amount of “nighttime” viewing it affords. Radio telescopes are large in part to improve their angular resolution, which is poor because of the long wavelengths at which they are used to observe the skies.
What advantages do space telescopes have and what advantages do ground telescopes have?
What are the disadvantages of space-based telescopes?
The disadvantages are mainly to do with the hassle of operating in space. It’s much more expensive, so you can’t have such a large telescope. If things go wrong it’s much harder to repair them. You can’t update the instruments so often so they quickly become out of date.
What is a space-based telescope?
How do space telescopes work?
It gathers light emanating from celestial objects with its large 2.4-meter primary mirror, and reflects the light toward its secondary mirror. This mirror focuses the light onto scientific instruments like cameras and spectrographs.
