An advertisement has put forward a supposed "invention" to eliminate estela, a theory with no scientific basis.
## The claim of a supposed "invention"
An advertisement has appeared promoting a device as the definitive solution to so-called "estela". This concept, popularized in conspiracy circles, refers to the belief that aircraft condensation trails are in fact chemicals deliberately sprayed into the atmosphere for hidden purposes. The post, shared on social media, presents the product as a tool to "neutralize" these supposed emissions.
## The context of conspiracy theories
The estela idea is not new. For years, various theories have suggested that governments or secret entities use aircraft to disperse chemicals for purposes ranging from weather control to manipulation of the population. However, the scientific community has repeatedly debunked these claims. The visible trails behind aircraft are actually condensation trails, formed by the rapid freezing of water vapor in the atmosphere at high altitude.
## The scientific reality behind contrails
Condensation trails, or "contrails", are a well-understood meteorological phenomenon. They form when the water vapor expelled by aircraft engines cools rapidly in the cold, dry air of the upper atmosphere, freezing into small ice crystals. The persistence and appearance of these trails depend on factors such as altitude, temperature and air humidity. The scientific community, including organizations such as **NASA** and the **World Meteorological Organization**, has explained on numerous occasions that there is no scientific evidence supporting the existence of estela.
