They scaled the albedo, which refers to the light being reflected by the Exoplanet dubbed WASP-12b in order to unveil more about the composition of the planet's atmosphere.
As exoplanet WASP-12b is situated close to its parent star WASP-12A, closer than the distance at which Mercury orbits the Sun, it is categorised as a hot Jupiter .
For those planets, it is suggested that things like clouds and alkali metals are the reason for the absorption of light, but those don't work for WASP-12b because it is so incredibly hot," explains Taylor Bell, the lead author of this research.
They found that the exoplanet HD 189733b possessed a deep blue colour, whereas WASP-12b didn't emit light at any wavelength, which made it pitch black.
The pitch black exoplanet WASP-12b is situated closer to its parent star WASP-12A than Mercury orbits the Sun, it is categorised as a 'hot Jupiter'.
