Scientists Observe Carbon Dioxide on Planets Outside the Solar System for the First Time
The findings provide strong evidence that four giant exoplanets 130 light-years from Earth formed much like Jupiter and Saturn.
The gas has been observed directly by the James Webb Space Telescope on four exoplanets, all belonging to the HR 8799 system, located 130 light-years from Earth. “We have other lines of evidence that point to the formation of these four planets in HR 8799 by this bottom-up approach,” Laurent Pueyo, an astronomer at the Space Telescope Science Institute and coauthor of the paper, said in a statement to NASA. This setting, similar to a solar eclipse, allowed the team to look for infrared light at wavelengths coming from the planet that reveal specific gases and other atmospheric details.
