Today most of the pollution in our world is caused by human actions. Especially nitrogen dioxide is a combustion process. Was released from the vehicle Or from power plants using fossil or fossil fuel It is said that there is a human being that pollutes there. Scientists from the Goddard Space Flight Center NASA agency In the usa It was therefore observed that nitrogen dioxide on habitable planets May indicate the existence of an industrial boom
Therefore, if there is a high-class civilization outside the Earth that is intelligent life living in a nearby star system, We may be able to detect it by looking for signs of air pollution being released. Astronomers now have found slotxo more than 4,000 planets orbiting other stars. Some eyes may have conditions that are suitable for life. But in these habitable stars Some living beings may have evolved to the point of forming a technological civilization. But it's very far Scientists could not look for signs of life or civilization by sending spacecraft to these distant Earths. A powerful telescope was needed to see what was in the atmosphere of those exoplanets.
However, since nitrogen dioxide is naturally occurring as well. Scientists therefore have to carefully analyze exoplanets to see if they contain nitrogen dioxide that could be caused by society of technology. If there are signs of technology in the distant world That means that we are not alone in this universe.
