ESA/Hubble In a first for astronomers surveying the depths of space, carbon dioxide has been detected on an exoplanet – that is, a planet lying outside our solar system. Thanks to the coronagraph ...

Last week, astronomers unveiled exciting new images of planets in the HR 8799 and 51 Eridani star systems — and it was all thanks to a creative use of the James Webb Space Telescope (JWST). William ...

Webb’s data shows that HR 8799’s four gas giants likely formed via core accretion, the same process that shaped Jupiter and Saturn in our solar system. Webb detected carbon dioxide and carbon ...

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 ...

The HR 8799 system, 130 light years from Earth, is only 30 million years old — just a baby compared to our solar system's 4.6 billion years. A U.S.-led team of researchers used Webb to directly ...

This discovery, within the HR 8799 planetary system, enhances our understanding of planetary formation and the potential for life beyond Earth. The detection of a heavier element like carbon ...

This discovery opens a new window into understanding planetary systems. Located 130 light-years away, the HR 8799 system hosts four giant planets that have long intrigued scientists. Webb's ...

Here’s how it works. Last week, astronomers unveiled exciting new images of planets in the HR 8799 and 51 Eridani star systems — and it was all thanks to a creative use of the James Webb Space ...
