ALT An artist's concept illustration shows three-quarters of a large exoplanet in the right foreground with a distant red star and a companion planet in the distance against the star-filled background of space. The planet is hazy and blue. It is labeled Artist's concept in the bottom right corner. Credits: Illustration: NASA, CSA, ESA, J. Olmsted (STScI), Science: N. Madhusudhan (Cambridge University)
ALT Illustration of an exoplanet planet and its red cool dwarf star on a black background that is speckled with some small stars. The planet is large, in the foreground on the right and the star is smaller, in the background at the lower left. The planet is various shades of blue, with wisps of white scattered throughout. The left edge of the planet (the side facing the star) is lit, while the rest is in shadow. The star has a bright red glow.
ALT The graphic shows the spectra of the exoplanet K2-18 b from NIRISS and NIRSpec in the form of a graph, with the vertical y-axis labelled as Amount of Light Blocked and the horizontal axis labelled as Wavelength of Light (microns). The spectra is plotted as dots with vertical short vertical lines across the plot, with the best-fit model as a blue jagged white line.There are green, yellow and light blue vertical columns of varying thicknesses scattered across the plot indicating where variations in the line represent the presence of methane, carbon di
