Spectra of Exoplanets

Caption: This graph shows the spectra of all four planets orbiting HR 8799. The plot shows how bright each object is (y-axis) versus the wavelength of light or color measured. Dips and peaks in these plots are due to the presence or absence of certain molecules (indicated at the top of the plot).
