Σύνοψη	Transmission spectroscopy is a technique for studying the atmospheres of exoplanets by analyzing the light passing through the planetary atmosphere during transit. Pioneered by David Charbonneau in 2002 with the detection of sodium in HD 209458b's atmosphere, this method has become the primary tool for characterizing exoplanet atmospheres and searching for biosignatures.	Stellar population synthesis is a technique for modeling the integrated light from a galaxy by summing the contributions of all individual stars formed at different times and with different masses and metallicities. Developed systematically by Bruzual and Charlot (2003), this approach enables estimation of fundamental galaxy properties from observations without detailed knowledge of individual stars.
