James Webb Space Telescope found carbon dioxide on Pluto’s largest moon

Using the James Webb Space Telescope (JWST), astronomers discovered the presence of carbon dioxide and hydrogen peroxide on the northern hemisphere of Pluto’s largest moon – Charon. To see the existence of the compounds, the James Webb Space Telescope uses a technique called Spectrography. With the spectral analysis, the study found that CO2 is present in pure crystalline form and, possibly, in intimately mixed states on the surface. Charon’s observations also confirmed the signatures of previously known crystalline water ice.
