HR 8799 c is a gas giant exoplanet discovered orbiting the young A-type star HR 8799. It’s notable as one of the first planets directly imaged around another star and part of a multi-planet system. This planet, approximately twice the size of Jupiter, offers scientists a unique opportunity to study...

HR 8799 b is a young gas giant exoplanet discovered orbiting the star HR 8799, located approximately 129 light-years from Earth. Direct imaging by the Keck and Gemini telescopes in 2008 revealed its existence. This planet is notable for its youth and association with a multi-planet system around an...

HR 8799 e is a gas giant exoplanet discovered orbiting the young star HR 8799. Its significance lies as the innermost planet within a confirmed multi-planet system – the first such system directly imaged. This inner giant, located approximately 129 light-years away, offers valuable insights for astr...

HR 8799 d is a gas giant exoplanet located approximately 129 light-years from Earth. It’s notable as one of the first planets directly imaged around an A-type star and part of a multi-planet system discovered through direct imaging techniques. This planet orbits a young, Sun-like star and offers val...

HIP 65426 b is a young gas giant exoplanet observed through direct imaging by the James Webb Space Telescope. Its notable characteristic is its youth and location around a newly forming star. Scientists study this planet to understand planetary formation processes within protoplanetary disks, partic...

WASP-189b is a giant exoplanet orbiting a young A-type star. It’s notable for being one of the hottest known exoplanets, reaching dayside temperatures around 3400 Kelvin. Its ultrashort orbital period makes it an ideal target for studying atmospheric processes and transiting planets. Astronomers and...

Beta Pictoris c is a gas giant exoplanet orbiting the young A-type star Beta Pictoris, located approximately 63 light-years from Earth and estimated to be around 23 million years old. The planet was initially detected through radial velocity measurements and was subsequently directly imaged by the G...

HD 95086 b is a directly imaged gas giant exoplanet orbiting the young star HD 95086 about 300 light-years away, discovered in 2013 with the Very Large Telescope and among the lowest-mass imaged then.
