Why would radio astronomers build identical radio telescopes in different places around the world?
There are at least two reasons why identical radio telescopes may be built. A mundane reason would to save money by reusing the same design. But the reason why most identical systems are built (not to say that saving money by reusing the design isn't still a factor in these cases) is to construct a "very long baseline interferometer", a type of multiple telescope system that uses properties of electromagnetic radiation (wave interference) to simulate telescopes with much larger apertures. This method attains the angular resolution of the larger telescope, but not the signal sensitivity.
What else can I help you with?
Is the telescope manned?
Terrestrial telescopes are generally manned, while space telescopes are unmanned. However, to a greater and greater extent, the people doing the observing are not the people actually manning the telescopes; the observations are done remotely from other universities around the world. The various space telescopes, such as the Hubble, the Kepler, or the Spitzer, or the soon-to-be-launched Webb, are remotely controlled in the same manner that everything is controlled these days; remotely, via computer.
How long has the telescope been around?
The invention of the telescope is generally attributed to Hans Lippershey in 1608. The first practical telescopes were developed by Galileo Galilei in 1609. So, telescopes have been around for over 400 years.
What percent are people around the world genetically identical?
Considering a Chimp's DNA is 99% identical to a humans I would think that people around the world are 99.99999% genetically identical
Why must astronomers use infrared telescopes to observe the motions of stars around Sgr A?
Studying universe in IR (infrared) wavelength is called infrared astronomy. Because of lot's of parameters such as redshift (for far objects like early galaxies) it is very interesting for modern astronomy and most of future studying in this field will be on these wavelengths. Next generation of space telescopes (like WEBB) will observe in IR too.
What makes the spitzer different from other telescopes?
The Spitzer Space Telescope is designed to primarily observe infrared radiation, which allows it to study cool or dusty objects in space that are otherwise difficult to see with visible light telescopes. Its location in space, trailing Earth around the Sun, also enables it to maintain a consistently cold temperature for its instruments, crucial for infrared observations.
What are X-ray and gamma ray telescopes used for?
X-ray and gamma ray telescopes are used to give us "alternate" views of objects in the universe. It is extremely helpful to see all of the different wavelengths of electromagnetic energies give off by objects to better understand what they are and how to classify them for further study. x-rays can also cause cancer whilst looking through them also a lamborghini can see more into the future than xray and gamma ray telescopes
What happens to the junk thrown by astronomers in the space station and space shuttles Does it stay afloat?
It usually stays in orbit around the earth, and poses a serious threat to all orbiting satellites. Even a small object can destroy things at high speed. Most satellites can move around projected paths of junk thrown in space. Some astronomers use radio telescopes to track "Space Junk".
When were telescopes first used?
Around 1608.
Where are telescopes location?
all around the world

What is the orgin for the word telescope?
Telescopes have been around since 1608, and they have been called "telescopes" the entire time. There is no original word.

Considering a Chimp's DNA is 99% identical to a humans I would think that people around the world are 99.99999% genetically identical
What have scientists learned from telescopes?
They have learned that Earth revolves around the Sun.
How much do astronomers get paid in a year?
Astronomers in the United States earn an average salary of around $110,000 per year. Salaries can vary depending on factors such as experience, education, location, and employer. Entry-level astronomers may start with lower salaries while more experienced astronomers can earn significantly higher salaries.
Why are astronomers important?
They help us understand the universe around us.
