JWST spectrum

Caption

The fraction of white dwarf starlight blocked by the planet WD1856b varies with wavelength in what is called a transmission spectrum. The planet blocks a record-breaking 56% of the light from its star. The spectrum measured by JWST (white data points) is explained (purple model curve) by absorption from methane (red bands) and small haze particles (slope at the short wavelengths) in the planet's atmosphere.
