When white light falls on and is then reflected off the surface or atmosphere of a planet, the elements and compounds on the surface and in the atmosphere of the planet modify the reflected light (e.g. they may absorb some of it).
Thus if you spread out the light reflected by the planet using a spectrometer attached to a telescope, you can see how the light has been modified and by analyzing the pattern of the modifications observed infer the elements and compounds on the planet or in its atmosphere that caused this.
This tells you what is in that planets atmosphere.

My cousin has a telescope and we set it up in the back yard and looked at the planets ourselves..Just buy a telescope or ask around to find out if any of your friends have one and you can see the planets for yourself. They are really there.

What property controls the quantity of atmosphere in planets?
Does space have an atmosphere or is it only planets that have them?
Space does not have an atmosphere. It is generally considered a vacuum. Planets and some moons have atmospheres.
How do the inner and outer planets atmosphere different?
the outer planets are gaseous and the inner planets are not
What are the two main reason why Jovian planets have much thicker atmoshperes than the Terrestrial planets?
While terrestrial planets are made of rock and have gases in the atmosphere, jovian planets are made almost entirly of gases. If an atmosphere is made of gases in a planet, then the atmosphere of the planets with more gases will be thicker.
What is the Name for planets whose atmosphere is made up of mostly gases?
atmosphere is made up of gases in all planets. But if you mean planets that are mostly atmosphere, then those are gas giants (Jupiter, Saturn, Neptune, Uranus)
Is atmosphere same in other planets?
No
Which of the planet other than earth has an atmosphere and season?

Is earth's atmosphere stronger than all the other planets' atmosphere?
A planet's atmosphere doesn't have strength.
What planet has many craters but no atmosphere?
There are probably a very great number of planets in our galaxy with no atmosphere. Of the 400+ planets that we know of, we can only determine the presence or absence of an atmosphere for the 8 planets in THIS solar system; our technology is not yet good enough to study atmospheres from several light-years distance. Of the planets of this solar system, we are fairly sure that Mercury has no atmosphere to speak of. Of the other seven, we know that Mars has a very thin atmosphere, but enough to use a parachute in. If we include dwarf planets, we can say with some certainty that Ceres doesn't have enough mass to retain an atmosphere, and Pluto's atmosphere is almost certainly all frozen by now.
How is the atmosphere of Venus different from that of other terrestrial planets?
yes
Explain why the surface temperatulre of Venus is higher than the surface temperatures of the other planets in your solar system?
you should be smart and know this! but i will give it to you any ways.... Venus's atmosphere has 90 times the pressure of the other planets!

Do all planets have wind?
In this solar system, yes. However, other planets in other systems may have had their atmosphere stripped away; thus they have no internal wind.
Does haumea have an atmosphere?

What does earth's atmosphere have that other planets don't?
Earth's atmosphere has a unique composition compared to other planets. It contains a significant amount of oxygen, which supports the existence of complex life forms. Additionally, Earth's atmosphere has an ozone layer, which protects the planet from harmful ultraviolet radiation. Lastly, Earth's atmosphere is denser than most other planets, allowing for the regulation of temperature and the retention of water on its surface.
