Because it works with pure, fresh, clean light, and not the stuff
that has been dragged through several miles of air first.
By the way ... there's only one single Hubble Space Telescope. On
April 24, 2014, it'll polish off a cool 24 years operating in Earth orbit !
One word, ATMOSPHERE. Even on Earth, you will notice that the most useful observatories tend to be high up e.g. in the Andes, on the high mountains in Hawaii. The air is much clearer in such places due to the atmosphere being thinner. Where the Hubble is, there is virtually no atmosphere so they get a much clearer and less distorted view.
It isn't necessarily "more useful" in general, but it does have some special advantages for certain types of work. For one thing, being above most of the atmosphere means that there is very little atmospheric distortion; also, since the atmosphere is less transparent to certain wavelengths, spectra measured at the Hubble are better able to determine some types of information than those obtained at ground-based instruments.
There is no atmosphere distortion in space looking out.
Because it orbits above the atmosphere which is responsible for the optical perturbation of longtime exposures.
Because the light that forms the Hubble's images doesn't have to
slosh through air before it enters the telescope.
Simply because there is no atmospheric interference. No dust, no clouds, and it can avoid easily any kind of glare from the sun or moon.
No atmospheric distortion.
No. The Hubble Space Telescope is an optical telescope of the reflective type. A 'non optical' telescope would be one that works on different portions of the electromagnetic spectrum below or above the optical wavelengths.
glasses binoculars telescopes dats all i got soz =)
optical telescope
anything likeSeismometers- Are used by seismologyto measure and record the size and force of seismic-wave.Tilt meter- is an instrument designed to measure very small changes from the horizontal level, either on the ground or in structures.Richter scale- Measure of the magnitude of seismic waves from an earthquake.Magnetometers- An instrument for measuring the magnitude and direction of a magnetic fieldAnemometer- Is an instrument use to determine the velocity, an anemometer detects change in some physical property of the fluid or the effect of the fluid on a mechanical device inserted into the flow.
Zacharias Janssen was the first person to invent the optical telescope. He is also known as the inventor of the compound microscope.
the optical telescope has discovered objects on earth and in space
A Telescope uses lenses or mirrors to collect and focus light from distant objects. With the advancement in optical research we are capable to watch the stars and planets better than before. Our information about universe largely depend on telescopes.
a telescope
A telescope is an optical system used to make objects, especially distant objects, appear larger/closer.
Radio telescopes collect radio waves. Optical telescopes capture visible light waves.
Basically, the catadioptric telescope is just one of the 3 main types of the optical telescopes.The other 2 main types of optical telescopes are the refracting telescopes and the reflecting telescopes.
They are optical telescopes.
A telescope can do that, but magnification is not its purpose.
As far as I know, there is no "optical radio telescope". There are, separately, optical telescopes (which work with visible light), and radio telescopes (which work with radio waves).
Reflecting telescopes are far-and-away the most common. This is because the telescope can be smaller and lighter, and because lenses always absorb a little light while mirrors can be almost perfect reflectors.
Space Telescope such as the Hubble Space Telescope
Some design variants you may see in an optical telescope include telescopes that fold or divert the optical path with mirrors and telescopes that use special lenses to enhance the images.
