Most telescopes use mirrors to see things in space. Mirrors make things look backwards though. They flip the image they are showing. ... The mirror or lens must be just the right shape.
Are reflecting telescopes used on Earth or in space?
In much of the short-wavelength region of the electromagnetic spectrum, telescopes must be located in space , because the high-energy photons cannot penetrate the earth's atmosphere. Ultraviolet telescopes have primary mirrors which are coated with special materials that make it possible to reflect ultraviolet light.
Why are some telescopes on Earth and some in space?
Telescopes are placed into orbit around the Earth or are sent farther out into space to get a clearer view of the Universe . There are many different types of space telescopes. Some are used to study a special object like the Sun. Others are used to study the different types of light given off by objects in space.
Can we see space telescope from Earth?
Hubble is best seen from areas of the Earth that are between the latitudes of 28.5 degrees north and 28.5 degrees south. This is because Hubble's orbit is inclined to the equator at 28.5 degrees. ... In contrast, the ISS passes over much more of the Earth because its orbit has a higher inclination at 51.6 degrees.
How does a telescope see in space?
The Near Infrared Camera and Multi-Object Spectrometer, or NICMOS, sees objects in deep space by sensing the heat they emit . It captures images and it is also a spectrograph. NICMOS helps scientists study how stars, galaxies and planetary systems form.
What are the disadvantages of having a telescope in space?
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?
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 reflecting telescope best used for?
If you are interested in brighter celestial objects like the Moon or planets or a beginner , a reflector telescope is ideal. Due to reflectors larger apertures at similar prices, they're usually going to be the best choice for almost all things visual.
What is the main reason that ultraviolet astronomy must be done in space?
What is the main reason that ultraviolet astronomy must be done in space? Earth's atmosphere absorbs most ultraviolet wavelengths.
Can you see the flag on the moon through a telescope?
Can you see an American flag on the moon with a telescope? Even the powerful Hubble Space Telescope isn't strong enough to capture pictures of the flags on the moon. But the Lunar Reconnaissance Orbiter, the unmanned spacecraft launched in 2009, is equipped with cameras to photograph the moon's surface .
Is Hubble still in space?
Thanks to their dedication and thoughtful work, Hubble will continue to build on its 31-year legacy , broadening our horizons with its view of the universe.” ... Launched in 1990, Hubble has been observing the universe for over 31 years.
Are there colors in space?
That's easy. It's in black and white . You might not know this, but almost every photo of space starts out this way. Additionally, most telescopes only take black-and-white pictures, the most prominent of which probably being the Hubble Telescope.
What are the disadvantages of the Hubble telescope?
Disadvantages. There are some limitations with the Hubble Space Telescope when imaging the Moon due to its sensitivity to light and it cannot image areas in the direction of the Sun. They are exceptionally expensive to build and position in place. Maintenance is difficult .
Which of the following is the biggest disadvantage of putting a telescope in space?
Which of the following is the biggest disadvantage of putting a telescope in space? Space telescopes are much more expensive than similar ground-based telescopes.
What are the pros and cons of space telescopes?
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.
