Signs of Advanced Civilizations: Interstellar Detectives Trace Alien Terraforming

In the quest to uncover extraterrestrial life, researchers have identified telltale greenhouse gases that could indicate advanced alien civilizations are actively terraforming distant planets.

The study focuses on unusual, potent gases like fluorinated methane and ethane, which, if detected, could serve as technosignatures of sophisticated interstellar engineering. Working as detectives on the hunt for intelligent life, astronomers using space telescopes such as the James Webb can trace these gases on distant exoplanets to find evidence of alien civilizations.
