The James Webb Space Telescope plans to explore strange, new rocky worlds in unprecedented detail.
The telescope’s scientific consortium has an ambitious agenda to study geology on these small planets from “50 light-years away”, they said in a statement Thursday (May 26). The work will be a big stretch for the new observatory, which should exit commissioning in a few weeks.
Rocky planets are more difficult to sight than gas giants in current telescope technology, due to the smaller planets’ relative brightness next to a star, and their relatively tiny size. But Webb’s powerful mirror and deep-space location should allow it to examine two planets slightly larger than Earth, known as “super-Earths.”
