The animation shows the results of the measurements carried out with the MIRI spectrograph of the JWST to characterise the exoplanet GJ 1214 b. From left to right: temperature curve along the east-west direction, centred around longitude zero, which indicates the point directly below the central star; heat map of the planet’s surface in Kelvin; emission spectra corresponding to the planet’s illumination phases shown in the centre (white data points). Three line indicate calculated spectra for three different temperatures in Kelvin (coloured).
