Direct Imaging: Advanced Connections

Direct imaging isolates photons from an exoplanet itself rather than inferring the planet only through its effect on the host star. Direct imaging enables atmospheric characterization and orbital tracking and is a key long-term route toward spectra of smaller temperate planets around nearby stars.

supported

A coronagraph blocks or destructively suppresses the star's diffraction pattern while preserving off-axis planet light.

supported

Systems such as HR 8799 show multiple planets tracked over years of orbital motion.
