8 Advantages and Disadvantages of Hubble Space Telescope
What are some advantages of the 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 the advantages and disadvantages of telescope?
Advantages and Disadvantages of an Astronomical Telescope
What are the disadvantages of putting telescopes 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 is the disadvantages of telescope?
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 You can’t update the instruments so often so they quickly become out of date.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 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.
Why can’t the Hubble see Mercury?
Hubble has observed all the planets in our Solar System, apart from Earth and Mercury. Hubble can’t observe Mercury as it is too close to the Sun, whose brightness would damage the telescope’s sensitive instruments.
What can Hubble telescope not see?
That also means that Hubble can’t observe Mercury, Venus and certain stars that are close to the sun either. In addition to the brightness of objects, Hubble’s orbit also restricts what can be seen. Sometimes, targets that astronomers would like Hubble to observe are obstructed by the Earth itself as Hubble orbits.
Because of the protective effect of the atmosphere, ground-based telescopes can’t pick up the lethal, invisible portions of the electromagnetic spectrum such as ultraviolet rays, x-rays and gamma rays.
The Hubble Space Telescope can see out to a distance of several billions of light-years. A light-year is the distance that light travels in 1 year.
What are the advantages and disadvantages of a space based telescope to an earth based one?
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 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.
How do we observe space?
Space telescopes Objects in the universe emit other electromagnetic radiation such as infrared, X-rays and gamma rays. These are all blocked by the Earth’s atmosphere, but can be detected by telescopes placed in orbit round the Earth. Telescopes in space can observe the whole sky and can operate both night and day.
Is used to observe space?
A space observatory is any instrument in outer space which is used for observation of distant planets, galaxies, and other outer space objects. A large number of observatories have been launched into orbit, and most of them have greatly enhanced our knowledge of the cosmos.
Where do we live in the universe?
Milky Way Galaxy Our home galaxy, composed of 200 billion to 400 billion stars and filled with the interstellar medium. The Milky Way and those satellite dwarf galaxies gravitationally bound to it.
How did we observe the universe?
The observable universe is a ball-shaped region of the universe comprising all matter that can be observed from Earth or its space-based telescopes and exploratory probes at the present time, because the electromagnetic radiation from these objects has had time to reach the Solar System and Earth since the beginning of …
How long will the universe exist?
It is expected that between 1011 (100 billion) and 1012 (1 trillion) years from now, their orbits will decay and the entire Local Group will merge into one large galaxy.
