ALT Modified version of a previous, popular artist illustration of the TRAPPIST-1 star system. The background is black. At the top there is a “TRAPPIST-1 System” label in bold white text. At far left is a representation of the TRAPPIST-1 star, an M class dwarf star. It is seen as a glowing orange-yellow semi-circle. To the right of the star, illustrations of its planets are shown in a line. There are seven, with slight variations in sizes. They are labeled b, c, d, e, f, g and h, with b being closest to the star. They all resemble mottled clay marbles in browns and dark greens. The planet TRAPPIST-1 b has been spotlighted to stand out. The other planets are dimmed down to be less visible. The planet b also has a white label as opposed to gray letter labels for the rest of the planets. At bottom right is the word “Illustration (2018)” in tiny gray text.
