[Article] A Paper by Researcher Lana Sinapayen et al. Published in The Astrophysical Journal

A paper by Researcher Lana Sinapayen et al. has been published in the academic journal The Astrophysical Journal.

The paper focuses on an “agnostic biosignature” and proposes a theoretical approach to identifying the presence of extraterrestrial life by examining patterns observed across multiple planets, without relying on a specific definition of life or a single indicator.
