Story summary

A study at the Carl Sagan Institute, led by Ligia Coelho, investigates life in exoplanet clouds.
Researchers build on Carl Sagan's work by examining microbes from Earth's upper atmosphere and cultivating them for tests.
They analyze pigments to create detectable spectral signatures and run Exo-Prime II simulations of cloud-bearing worlds.
The results suggest high microbial colonization may be needed for detection, yet exoplanet clouds could still host life.
