Explain how a radio telescope works. What is the advantage of a radio telescope over a standard optical telescope? What is its disadvantage?
my subject is earth science.i hope you can help me on this questions.pls.

A radio telescope uses(”sees”) a different range of wavelengths as light does. So you can see things not to be seen by an optical telescope. Monitors make the radio waves visible to your eyes.

You've probably heard a lot about satellite radio lately, and no doubt it will be heard even more about it soon. If you have not adopted this new technology in its mix of entertainment and information, then you can not understand very well. So let's help get information on how does this new technology.

You've probably guessed that satellites are involved due to the name satellite radio, and it would be correct. But first the programming is recorded in digital form studies that the signal contains much more and higher quality sound than is possible with standard radio. In that recording becomes a signal that is transmitted to satellites orbiting the Earth over 20,000 miles high in the atmosphere. There, signal is encoded and sent to a receiver that decodes the signal and hear the sound for you.

All is quite fast, easy and reliable due to advanced technology. All you need to have to be able to take advantage of this technology is three things: a subscription to a provider of radio services satellite receiver and antenna.

There are currently three major satellite radio providers, but only two, Sirius and XM are available in the U.S.. The third is a company called WorldSpace that has a more global view of the potential for satellite radio has and is available in Asia, Africa, Europe and South America. All you have to do is choose the company whose programming seems to best fit what you are interested in hearing and the first step is do.

Now that you have the programming available, wuill need the equipment to receive the special signals since normal radios cannmot decode the signal Satellite radio, unless they already have that capability and are equipped to do so. Do not miss the places where if you can get satellite radio equipment and including installation on your boat, car and RV. You can usually get very good deals on radio receiving equipment that you can install yourself or have installed locally. Very often you can even buy the equipment they are allowed to use a satellite radio receiver in several places, including your home, car, RV, etc. You just get the receiver with you as you go.

More and more companies of new cars including the installation of satellite radio as standard equipment on vehicles, so they expect this technology to grow, improve and become more accepted as time passes. We believe that if you just take some time to hear a station satellite radio for a while, you begin to understand and appreciate what a pleasure it is to have.
