A study from the Institute of Astrophysics and Space Sciences shows how scientists could study exoplanets using Venus as a model.By treating Venus as a distant exoplanet, researchers tested techniques to analyze the atmospheres of smaller planets like Earth and Venus.Data from the 2012 Venus transit, combined with current methods, proved effective in studying smaller planets.Future telescopes like the ELT and space missions like Ariel will enhance research in studying exoplanets and expanding understanding.
