Why is it a advantage for reflecting and refracting telescopes to be made larger?
The reason people build larger Telescopes is because smaller telescopes have a smaller power to them, which results in less detail the farther they look. Larger telescopes use much larger lenses to see much farther and with much more clarity.
What are the three things which have helped to build a friendship between Canada and the US?
The main three things which have helped build a friendship between Canada and the US are their common borders, trade, and language. The geographical situation of both countries has allowed for a larger amount of trade, which is also improved by having the same language.
Did Don Cheadle play in Blue Hill Avenue?
No. The role of Twinkie is played by Marlon Young, but in the elaborate wig and facial hair,he does look like Cheadle, and sounds a lot like him. Young is about 2 years older than Cheadle, and has a larger build.

Where should astronomers build their telescopes?
The best place for astronomers to build their telescopes is a cold, dry, and calm place. Astronomers identified a place in the Antarctic that they believe is the best place for an observatory. Read more about it at http://phys.org/news170932769.html.

Why are most modern telescopes reflecting telescopes?
Most modern telescopes are reflecting telescopes because reflecting telescopes are generally more cost-effective and easier to build at larger sizes compared to refracting telescopes. Reflecting telescopes also suffer less from chromatic aberration and can have a simpler design with fewer optical elements.
How many telescopes did herschal build?
6 and a half
Who built and used reflecting telescopes?
Thousands of people still do build their own astronomical telescopes; it isn't that hard to do.
Do astronomers know how to build?
Some astronomers are likely to be good at DIY, but most would probably get a contractor in.

Did Sir Issac Newton build and use reflecting telescopes?
Yes.
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.
Why are most large telescopes reflecting telescopes?
They are refracting telescopes(:Large refracting telescopes are no longer built because there were too many problems with them. There was color distortion, light pollution, and when the object hits the focal point it turns upside down. Then you don't see the object for what it really is, you see it upside down and weird-ed out. They are to complicated and scientists believed they should just stick with the simple, small, original refracting telescopes!!!!-Meghan Betts (8th grader)
Methods that are used to explore the universe?
The universe can be explored by astronomical instruments called telescopes, and by space probes sent from earth to other planets. When using telescopes astronomers try to look at the energy being produced by the universe not just in the visible part of the spectrum (where our eyes can see) but at the whole range of electromagnetic radiation. We thus have radio telescopes, infrared telescopes, X-ray telescopes and even some telescopes that are buried deep underground looking for neutrinos. Most of the telescopes are set in mountains for they can rich more.
What is the the primary reason for making telescopes very large?
Large telescopes are needed to collect the weak radiation, coming from faint or very distant sources. The larger the aperture, the brighter the final image will be. The aperture also has to be much larger than the wave length of the radiation being observed otherwise diffraction will spread the star light out and the image will be blurred not sharp. Radio waves have a very large wave length, so these telescopes are enormous! The resolving power of a telescope measures how well it can distinguish stars that appear close together. It depends on both the aperture size and the wavelength used. Aperture=light-gathering area of the telescope.
