Some exoplanets have been directly imaged from "summary" of Exoplanets and Alien Solar Systems by Tahir Yaqoob
Direct imaging of exoplanets is a remarkable feat achieved by astronomers using advanced technology and techniques. This method involves capturing actual images of distant planets outside our solar system. It allows scientists to study the physical characteristics of these exoplanets, such as their size, composition, and atmosphere, providing valuable insights into their nature and potential habitability. One of the main challenges in directly imaging exoplanets is the overwhelming brightness of their host stars, which can overshadow the faint light emitted by the planets themselves. To overcome this obstacle, astronomers use specialized instruments like coronagraphs or starshades to block out the starlight and reveal the presence of orbiting planets. By selectively blocking the intense glare of the star, researchers can detect the much weaker signals from the exoplanets orb...
