. Which Observations Would Require You To Launch A Telescope Above The Earth’S Atmosphere?

What is the purpose of placing a telescope above the Earth’s atmosphere?

  • A telescope positioned above the Earth’s atmosphere would be able to detect light emitted by stars, galaxies, and other objects in space before the light is absorbed or distorted by the atmosphere. Therefore, the vision would be far sharper than that obtained by even the greatest telescope on the planet’s surface

Which of the following telescopes must be used above the Earth’s atmosphere?

A UV telescope is quite similar to a standard visible light telescope, with the exception of the use of carefully chosen materials for filters. The fundamental distinction is that in order to see cosmic sources, the UV telescope must be located above the Earth’s atmosphere. A specialized UV observatory, the GALEX observatory was the most recent such facility.

Why do we observe stars from above Earth’s atmosphere?

The rationale is that the Earth’s atmosphere has the potential to absorb a significant amount of the ultraviolet radiation that comes from space. Furthermore, the vast majority of celestial objects emit these rays. As a result, it becomes more vital for us to see stars and other celestial objects from above the Earth’s atmosphere in order to have a complete understanding of their characteristics.

What is the main purpose of using telescopes for astronomical observations?

The fundamental function of a telescope is to gather light across a broad surface area, with a secondary function being to magnify the picture of the object under study as a result of this collection.

Why do astronomers launch telescopes into space?

It is necessary to install telescopes in orbit around the Earth or to send them further out into space in order to obtain a sharper picture of the Universe. There are several different types of space telescopes available for purchase. Some are used to investigate a specific object, such as the Sun. Others are employed in the investigation of the many forms of light emitted by objects in space.

What advantages do space telescopes have over telescopes used on Earth?

Space telescopes have the benefit of being above the obscuring effects of the Earth’s atmosphere, which allows them to see more clearly. On top of all of that, there are several wavelengths from the electromagnetic spectrum that do not reach the Earth because they have been absorbed or reflected by the planet’s atmosphere.

What do gamma ray telescopes observe?

An equipment that detects and resolves gamma rays from sources outside the Earth’s atmosphere is referred to as a gamma-ray telescope. The Cherenkov radiation created when a gamma ray impacts the Earth’s upper atmosphere, on the other hand, may be observed by some ground-based telescopes.

What were two observations that Galileo made through his telescope that supported the heliocentric model?

He found that the sun contains sunspots, which are black spots that emerge on the surface of the sun. Because of Galileo’s findings regarding the Moon, Jupiter’s moons and Venus, as well as sunspots, he was able to demonstrate that the Sun, not the Earth, was the center of the universe, which was contrary to popular belief at the time.

What type of telescope is the Hubble space telescope?

Hubble is a Cassegrain reflector telescope, which means it has a curved mirror. Light from astronomical objects goes down a tube, is captured by a bowl-shaped, internally curved primary mirror, and is reflected toward a smaller, dome-shaped, outwards curved secondary mirror at the other end of the tube

Which types of telescopes are orbiting around the earth why it is necessary to put them in space?

What is the justification for putting them in space? (1) The numerous types of telescopes circling the Earth include optical telescopes (Hubble), X-ray telescopes (Chandra), and other sorts of observatories. (ii) Because of this, these telescopes have been installed in space. Some of the light emitted by celestial bodies is absorbed by the earth’s atmosphere, as seen in Figure 1.

What is an astronomical telescope?

astronomical telescope definition: a telescope that is built for seeing celestial bodies and does not require the use of an image-rectification device — as opposed to the terrestrial telescope.

What has the telescope helped us discover?

Telescopes have provided us with a new perspective on the cosmos. Early telescopes revealed that the Earth was not in the center of the cosmos, as had previously been assumed by the scientific community. Mountain ranges and craters were also shown on the moon. Geopolitics and weather on the planets of our solar system have been exposed by later telescopes.

How does a telescope work optics?

Our ability to see further is enhanced by the use of optical telescopes, which are capable of collecting and focusing more light from distant objects than our eyes alone. This is accomplished by the use of lenses or mirrors to refract or reflect the incoming light. This second lens is then in charge of concentrating the light so that it produces a clear image of the item in question.

Why do we have space based telescopes Why do we not simply make our observations from the ground?

The primary reason for this is because our planet’s atmosphere does not interfere with the operation of space telescopes. While the atmosphere allows visible light to get through, which our eyes are sensitive to, it absorbs light at other wavelengths, which means we will never be able to see them from the ground.
