The atmosphere of the Earth filters out and blocks plenty of radiation from outer space. Thus, telescopes are placed on satellites to glean information from these rays that would otherwise not be able to reach Earth-based telescopes.
Radio telescopes are generally much larger than optical telescopes for two reasons: First, the amount of radio radiation reaching Earth from space is tiny compared with optical wavelengths, so a large collecting area is essential. Second, the long wavelengths of radio waves mean that diffraction severely limits the resolution unless large instruments are used.
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.
Some telescopes are on the earth this is because they are easier to maintain as it does not require launches to get astronaughts up there to fix them. Also they are cheaper having to make a telescope usable in space takes time and money, it also requires a launch which is expensive as well. It is easier to view the results as you can view them directly from the telescopes, instead of them having to be sent from space down to earth using microwaves then you need an antenna and other.
Some reasons why the damage from the earthquake was severe could include the earthquake's magnitude and depth, the proximity of populated areas to the epicenter, the quality of building construction in the region, and the local geological conditions that amplify seismic waves.
A natural celestial body that orbits a planet is called a satellite. Moons are satellites of planets. The Earth has one moon, but other planets like Jupiter and Uranus have many moons or satellites.
because the people of the world suck their dicks very hard
The settlers were looking gor gold instead of farming or building houses
One reason for sending telescopes into space is so that people can get a better look at the stars the second reason for this is so that scientist can discover more about stars.
Windows that open inwards instead of outwards are designed this way for safety reasons. Inward-opening windows are harder for intruders to access from the outside, providing better security for the home or building.
Telescopes in space are able to view objects clearly without having to look through a thick layer of the Earth's atmosphere. This enables them to capture better pictures and observe dimmer and more distant objects.
I've never seen a book that deals with this question. But I suspect that if the questioner is able to discover an answer some day, the answer will be related somehow to the reasons why Mercury and Venus have no satellites, why Jupiter and Saturn have at least 60 satellites apiece, and why the sun has only eight or nine planets.
so he can have his own capital.
Four reasons for building a nation might include creation of a national identity, cohesion of a society, cohesion of government, and the creation of economic stability.
It has good reasons or good memories from it
