Webb‘s ability to analyze exoplanet atmospheres ... to our solar system’s 4.6 billion years. Its planets still radiate heat from their formation, emitting strong infrared signals. These signals allow ...

In particular, it has made strides in the analysis of their atmospheres by studying light from the parent star as it travels through the gas surrounding the planets. JWST recently observed gas giant ...

Yet, Webb‘s ability to directly detect the light from these exoplanets has provided a wealth of new data, including the key ...

"By spotting these strong carbon dioxide features, we have shown there is a sizable fraction of heavier elements, like carbon, oxygen, and iron, in these planets' atmospheres. Given what we know ...

The blue and yellow lines are a best-fit model for an atmosphere that would be either low or high in metals heavier than helium, including carbon, also known as metallicity. The Webb data is ...

They also confirm Webb can do more than infer atmospheric composition ... HR 8799 planets emit large amounts of infrared light that give scientists valuable data on how their formation compares ...

The observations provide strong evidence that the system's four giant planets formed in much the same way as Jupiter and Saturn, by slowly building solid cores. They also confirm Webb can do more than ...

For the first time, Webb has directly detected carbon dioxide in an exoplanet’s atmosphere ... solar system’s 4.6 billion years. Still hot from their violent formation, HR 8799 planets emit large ...

“By spotting these strong carbon dioxide features, we have shown there is a sizable fraction of heavier elements, such as carbon, oxygen, and iron, in these planets’ atmospheres,” said ...

(Pablo Carlos Budassi) In a new Astrophysical Journal Letters paper, researchers from the University of California, Riverside, describe these gases, which could be detected in the atmospheres of ...
