The background is black. At the center there is a symbol representing a star labeled HR 8799. The star\u2019s light is blocked. There are four exoplanets, which look like fuzzy dots, pictured surrounding the star. Furthest from the star is a fuzzy, faint blue dot, labeled b, at the 10 o\u2019clock position. At the 1 o\u2019clock position, second furthest from the star is a blueish-white fuzzy dot labeled c. Just below that is an orange dot labeled e.
