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 the advantages of putting telescopes in space?
Space telescopes have the advantage of being above the blurring effects of the Earth’s atmosphere. In addition, there are many wavelengths from the electromagnetic spectrum that do not reach Earth because they are absorbed or reflected by the Earth’s atmosphere.
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.
Why is it better to place telescopes on a satellite in space rather than placing them on the ground?
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 the advantages of placing telescopes in space quizlet?
What are the advantages of putting telescopes in space? allows us to observe the rest of electromagnetic spectrum that does not reach ground/sea level.
What advantage do space telescopes have over Earth based telescopes quizlet?
What advantages do space telescopes have over Earth-based telescopes? Space telescopes orbit above Earth’s atmosphere and thus produce clearer images than Earth-based telescopes.
Why is it important for telescopes other than optical telescopes to be built and used by astronomers?
Astronomers use a variety of telescopes to look at the universe. They need many different types of telescopes to look at space because each telescope shows them different things. Light comes in wavelengths from short to long. … Longer wavelengths include microwaves and radio waves.
How do telescopes help us to view distant objects?
Telescopes collect and magnify the light from distant objects. The problem with observing objects in the night sky is that they are so far away and therefore appear extremely faint. The more light that can be collected with a telescope, the better we can see these objects.
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 main advantages of an optical telescope over the unaided eye?
So the telescope can gather light for 900 times longer than the eye, to make a single image! The long exposure time of the telescope’s camera enables it to gather much more light than the eye. This enables telescopes to detect much fainter objects than the unaided eye.
What does NASA’s Sofia stand for?
SOFIA, the Stratospheric Observatory for Infrared Astronomy, is a Boeing 747SP aircraft modified to carry a 2.7-meter (106-inch) reflecting telescope (with an effective diameter of 2.5 meters or 100 inches).
Why do we need space based telescopes quizlet?
Telescopes located outside earth’s atmosphere; located there because there is less light distortion caused by atmosphere; able to collect energy or information that doesn’t pass through earth’s atmosphere; Photo: Hubble Space Telescope orbiting earth.
