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.
What else can I help you with?
Why is earth inhabitable and other planets are not?
Earth is habitable because it has the right conditions to support life, such as a suitable atmosphere, liquid water, and a stable climate. Other planets may not be habitable due to extreme temperatures, lack of atmosphere, or high levels of radiation that make it difficult for life as we know it to survive.
Do any of the planets have oxygen in there atmosphere?
Among the planets in our solar system, Earth is the only one with a significant amount of oxygen in its atmosphere, primarily due to photosynthesis by plants and other organisms. Mars has a very thin atmosphere with trace amounts of oxygen, but it's not substantial enough to support life as we know it. Venus has a thick atmosphere dominated by carbon dioxide, with only a small fraction of oxygen present. Other planets and moons, like Titan (a moon of Saturn), have some complex organic compounds but lack free oxygen comparable to Earth's atmosphere.
What planet has a atmosphere with gases used by living things?
Earth is the only planet known to have an atmosphere rich in gases like oxygen and nitrogen, which are essential for supporting life as we know it. Other planets in our solar system have atmospheres with different compositions that would not support life as we know it.
Which planet has a large percentage of oxygen in its atmosphere?
Earth has the largest percentage of oxygen in its atmosphere compared to other planets in our solar system. Oxygen makes up about 21% of Earth's atmosphere, which is essential for supporting life as we know it.
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.
Is atmosphere same in other planets?
No
What is the atmosphere of other planets made up of?
cells
Is earth's atmosphere stronger than all the other planets' atmosphere?
A planet's atmosphere doesn't have strength.
How is the atmosphere of Venus different from that of other terrestrial planets?
yes
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.

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.
Do planets have Ozone?
Earth has an ozone layer in atmosphere. It is present in the stratospheric region. Other planets which have oxygen in their environment might have ozone.Some planets like earth do. Others might have.
Why do meteoroids hit Mercury but not other planets?
Meteoroids are small enough that they will usually disintegrate when they enter a planet's atmosphere. Mercury has no atmosphere to speak of, and so it is not shielded in this way. Larger asteroids still do strike other planets.
Do any other planets have an atmosphere like earths and if they did could it support life?
At the moment, no planets are known to have conditions similar to Earth's for supporting life. If there planets similar to Earth, there would definitely be living organisms of some sort. On the other hand, there is slightly less chance of sentinent life such as our own species existing.
Which of the planet other than earth has an atmosphere and season?
Mars has an atmosphere, although it is much thinner than Earth's, and experiences seasons similar to Earth due to its axial tilt. This results in temperature variations and changes in weather patterns on the planet.
