Overview

• 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.
