Three Ways to Find Life From Light-years Away: Comparing Exoplanet Biosignature Techniques
This article compares three primary remote sensing techniques—transmission spectroscopy, direct imaging, and phase curve analysis—used to detect biosignatures on exoplanets. It details their strengths, limitations, and the crucial role of complementary observations and false positive exclusion in confirming potential signs of extraterrestrial life.
