NASA’s James Webb Telescope captured direct images of gas giants in HR 8799, revealing their carbon dioxide-rich atmospheres.
Giant Exoplanets in HR 8799 System Likely Formed Like Jupiter and Saturn The first exoplanet was discovered in the 1990s, but ...
In 2022, the Webb telescope detected unequivocal evidence of carbon dioxide in the atmosphere of a distant exoplanet called ...
Abstract: HR 8799 is a λ Bootis, γ Doradus star hosting a planetary system and a debris disc with two rings. This makes this system a very interesting target for asteroseismic studies. This work is ...

First-ever: Webb captures direct image of carbon dioxide outside solar systemThis discovery by Webb provides strong evidence that the giant planets in HR 8799 formed through core accretion, much like ...
From this route, the resulting exoplanet would be expected to share roughly the same composition as its parent star. ‘The ...
NASA's James Webb Space Telescope has captured direct images of multiple gas giant planets within an iconic planetary system.
The findings provide strong evidence that four giant exoplanets 130 light-years from Earth formed much like Jupiter and ...
