A Planet’s Breathing Unveils the Mystery of Life ⚡ экспресс
Original: "Toward Inferring the Surface Fluxes of Biosignature Gases on Rocky Exoplanets from Telescope Spectra"
A new method searches for life not by the amount of gases in the atmosphere, but by how fast they’re released from the surface.

Scientists figured out how to tell a planet’s living breath from lifeless gases. Instead of merely sniffing the atmosphere, they measure the speed at which gases rise from the surface. The test showed an 80% chance of microbes. It’s like hearing oil sizzle and knowing it’s frying, not the wind rustling.
🎯 In deep time (2.5–4 billion years ago), Earth life was already busily pumping out methane, but oxygen was nearly absent. An alien telescope would spot not oxygen but methane paired with carbon dioxide — exactly as in this study.
🎬 Sci-fi devices that instantly sniff out life from the air just got a step closer: this method brings smart atmospheric scanners nearer to reality.
