Astrophysicists have observed the multi-planet “HR 8799” system located 130 light-years away, which has long been an important target for planet formation research. Utilizing the James Webb Space Telescope (JWST), researchers from Johns Hopkins University captured the first images of carbon dioxide detected in the atmosphere of a planet outside the Solar System. By using the coronagraph device on James Webb to take photographs of distant planets around stars, the researchers obtained images of carbon dioxide in the atmosphere of a planet beyond our Solar System. The findings also provide strong evidence that the system’s four giant planets, similar to Jupiter and Saturn, gradually formed solid cores. William Balmer, one of the study’s authors, stated, “Thanks to this discovery, we have shown that these planets contain a significant amount of heavy elements such as carbon, oxygen, and iron in their atmospheres.” The results of the study were published in “The Astrophysical Journal” journal.
