The analysis focused on two crucial biosignature pairs—oxygen and methane and ozone and methane. These pairs exhibited stronger signals in models of Earth approximately 100 million to 300 million years ago, a period marked by significantly higher oxygen levels.
The models simulated transmission spectra, also known as the light fingerprint, generated by an atmosphere that absorbs certain colours of starlight while allowing others to pass through. This information is essential for scientists to determine the composition of the atmosphere.
