Scientists studying a distant, Jupiter-like planet have found that its atmosphere gets altered by starlight from its host star.
NASA, ESA, CSA, Joseph Olmsted This illustration shows how the gas giant planet WASP-39 b might look as it orbits its host star.The James Webb Space Telescope has identified a rich mix of gases swirling in the skies of a hot, Jupiter-like world orbiting a star that's around 700-light years from Earth.
Understanding how it works on other worlds"is going to be crucial for understanding life on other planets," says Bean. Sometimes, however, they've been able to get clues about planets' atmospheres, by analyzing the starlight that filters through. That's because different molecules absorb different wavelengths of light.amount of water vapor in the atmosphere of this particular planet, called WASP-39 b.
"The Hubble observations have been confirmed, but we've gone so much deeper in understanding of this planet by revealing all these different molecules and being able to characterize their abundances much more precisely, and then to see things that we didn't really expect," says Bean.
