Recently, NASA wrote a piece describing the discovery of the molecule methane in the atmosphere of WASP-80b, as announced by Taylor Bell et al. in Nature.
Taylor Bell explains: “NASA has a history of sending spacecraft to the gas giants in our solar system to measure the amount of methane and other molecules in their atmospheres. Now, by having a measurement of the same gas in an exoplanet, we can start to perform an “apples-to-apples” comparison and see if the expectations from the solar system match what we see outside of it.”
The NASA piece led to widespread reporting of the finding on numerous websites.
