High-resolution spectroscopy is an advanced technique used to observe the fine details of spectral lines with great precision, allowing scientists to analyze the physical and chemical properties of astronomical objects. This method is crucial for detecting subtle changes in light, which can indicate the presence of exoplanets, their atmospheres, and even potential habitability by measuring elements like hydrogen and oxygen in those environments. It provides insights into the composition, temperature, and movement of celestial bodies, making it an essential tool in astrophysics.
