Scientists Propose Detecting Alien Terraforming Through Greenhouse Gas Signatures

New research suggests advanced civilizations might use specific gases to warm planets, detectable with current technology.

Researchers identified fluorinated gases as potential indicators of alien terraforming efforts.
These gases are more effective and stable than previously considered options like CFCs.
Detection of such gases could be possible with telescopes like the James Webb Space Telescope.
Simulations show even minimal concentrations of these gases could significantly alter a planet's climate.
The study highlights the potential for current astronomical tools to find evidence of extraterrestrial technological activity.
