Scientists have shifted the search for extraterrestrial life to include purple bacteria, suggesting that these organisms could be prevalent on exoplanets, especially those orbiting M-type stars. Traditional green landscapes, associated with oxygenic photosynthesis, are now complemented by models showing purple bacteria dominating exoplanetary surfaces. This broadens potential biosignatures detectable with upcoming powerful telescopes. By expanding our understanding of life-supporting conditions to encompass anoxic environments and different light spectra, researchers enhance our ability to detect and understand diverse life forms across the universe, potentially identifying new, habitable worlds marked by their distinctive purple hue.

In a novel study, scientists Harrison B. Smith and Lana Sinapayen from the Earth-Life Science Institute propose a new method for detecting extraterrestrial life that does not rely on Earth-centric biosignatures. Instead, their model uses statistical patterns from the process of panspermia and terraformation across planetary systems. By analyzing the correlations between planetary characteristics and spatial distributions, the researchers identify clusters of potentially life-altered planets without presupposing specific life forms or environmental conditions. This approach could revolutionize the search for life in the universe by focusing on life's effects rather than its direct manifestations.

Researchers have proposed a novel strategy to enhance the search for extraterrestrial intelligence by focusing on the Galactic Center, specifically utilizing the precise orbital movements of the star S2 around the Sagittarius A* black hole.
