NASA’s James Webb Space Telescope Could Study Planet 9

NASA’s James Webb Space Telescope (JWST) — arguably one of the most anticipated and talked about pieces of space hardware ever conceived — will certainly make observations of the ends of the universe that will likely shake cosmology to its core. But it would also be able to study the large super-earth — dubbed Planet 9 — that some astronomers think may lie some 900 AU (or Earth-Sun distances) away; at the outermost fringes of our own solar system.
