direct imaging

(detection/observation of exoplanets by taking pictures of it)

Direct imaging is a method of discovering and observing extra-solar planets, but can be done only for nearby stars, planets orbiting far from their stars (e.g., many AU), and hot (bright) planets and/or cool stars, e.g., brown dwarves. Planets have been observed and discovered using this technique, e.g., around HR 8799.

Direct imaging is considered a great advantage in spotting some types of biosignatures, such as any in the "shine" of the planets.

The term direct imaging also comes into use for other challenging-to-image objects such as protoplanetary disks.
