The clearest look in the infrared yet at the iconic multi-planet system HR 8799. Colors are applied to filters from Webb’s NIRCam (Near-Infrared Camera). A star symbol marks the location of the host ...
NASA’s James Webb Telescope captured detailed images of HR 8799’s exoplanets, revealing new insights into their formation, ...
NASA’s James Webb Telescope captured direct images of gas giants in HR 8799, revealing their carbon dioxide-rich atmospheres.
From this route, the resulting exoplanet would be expected to share roughly the same composition as its parent star. ‘The ...
The findings provide strong evidence that four giant exoplanets 130 light-years from Earth formed much like Jupiter and ...
In 2022, the Webb telescope detected unequivocal evidence of carbon dioxide in the atmosphere of a distant exoplanet called ...
