High-contrast imaging is a research area within the field of astronomy that focuses on developing techniques to image faint astronomical objects that are located close to bright sources, such as stars or galaxies. This type of imaging is important for studying exoplanets, as they are typically much dimmer than the stars they orbit. High-contrast imaging methods typically involve using advanced instruments and technologies, such as adaptive optics and coronagraphs, to block out the light from the bright source and enhance the visibility of the faint object. This research area is crucial for advancing our understanding of planetary systems beyond our own solar system.
