X-ray and gamma-ray telescopes study the hottest and most explosive objects in space. Infrared telescopes study the places where stars are born and can look into the centers of galaxies. Optical telescopes study the visible light from space and ultraviolet telescopes study very hot stars.
Why do astronomers need different telescopes at different locations to observe across the electromagnetic spectrum?
Why do astronomers need different telescope designs to observe across the electromagnetic spectrum? A) Light pollution is worse at radio wavelengths than visible wavelengths . ... Telescopes have to adapt to the greater distortion of the atmosphere at shorter wavelengths.
Why do we need different types of telescope for space observation?
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. Visible light, the light humans see, is in the middle of the range.
What are the disadvantages of space telescopes?
Disadvantages. Space telescopes are much more expensive to build than ground-based telescopes . Due to their location, space telescopes are also extremely difficult to maintain. The Hubble Space Telescope was serviced by the Space Shuttle, but most space telescopes cannot be serviced at all.
What are the advantages of space based observatories?
Do not contend with the effects of Earth’s atmosphere, which include scattered light and atmospheric absorption , both of which reduce the flux measured from a NEO on the ground, and atmospheric emission, which can blind a telescope to a NEO in the infrared.
Which type of telescope is best used to detect distant planets?
Refractor type telescopes will be better bets for lunar and planetary observations, while reflectors are the best options for deep-sky astronomy.
What are the instrument used to observe the universe?
The Hubble Space Telescope has three types of instruments that analyze light from the universe: cameras, spectrographs and interferometers.
What are the 3 main types of telescopes?
There are three main types of telescope. These are refracting telescopes, Newtonian telescopes and Schmidt-Cassegrain telescopes .
What is the most important factor to consider when purchasing a telescope?
The most important aspect of any telescope is its aperture , the diameter of its main optical component, which can be either a lens or a mirror. A scope’s aperture determines both its light-gathering ability (how bright the image appears) and its resolving power (how sharp the image appears).
What are the advantages and disadvantages of putting a telescope 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 the advantages of Hubble space telescope?
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 two key advantages of space 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 the purpose of the MOST space telescope?
MOST is the first space telescope to be entirely designed and built in Canada. It’s the only telescope on Earth or in space capable of detecting light from a star reflecting off a planet . This means that we can discover small, dark planets more easily.
Why is the Spitzer Space Telescope important?
The Spitzer Space Telescope is one of NASA’s “Great Observatories” designed to examine the universe over a broad range of wavelengths of light . Launched in 2003, Spitzer has scanned the skies in infrared light for 16 years. ... Over its lifetime, Spitzer revealed fascinating insights about our universe, near and far.
