Exoplanets have been discovered using several different methods for collecting or combining direct images to isolate planets from the background light of their star. Non-Redundant Aperture Masking Interferometry is a method of combining the views of multiple telescopes into a single image, while the other methods are algorithms for combining ...
Direct imaging of an Earth-like exoplanet requires extreme optothermal stability. [60] During the accretion phase of planetary formation, the star-planet contrast may be even better in H alpha than it is in infrared – an H alpha survey is currently underway. [61]
This is the list of exoplanets that were detected by the direct imaging. Properties (mass and semimajor axis) of planets discovered using the direct imaging, compared (light gray) with planets discovered using other methods.

The first confirmation of an exoplanet orbiting a main-sequence star was made in 1995, when a giant planet was found in a four-day orbit around the nearby star 51 Pegasi. Some exoplanets have been imaged directly by telescopes, but the vast majority have been detected through indirect methods, such as the transit method and the radial-velocity ...
51 Eridani b has relatively low C/O molar ratio of 0.38 ± 0.09. [9] The planet has the second strongest methane signature of any exoplanet, after GJ 504 b. [10] This methane signature, along with the low luminosity of the object, should produce additional clues as to how 51 Eridani b was formed. [5]
HD 95086 b, formally named Levantes, [2] is a confirmed, [5] directly imaged exoplanet orbiting the young, 17 Myr [6] A-class pre-main-sequence star HD 95086.It is roughly 5 times as massive as Jupiter and orbits about 70 AU away from the parent star.
