JWST Observes Super-Earth With Magma Ocean
James Webb Space Telescope observations of the planetary nebula RCW 103 support the theory of a jet-driven explosion of its core-collapse supernova remnant. The morphology of RCW 103 closely resembles the brightest regions observed in recent studies. The James Webb Space Telescope has observed planet L 98-59 d, a super-Earth located 35 light-years away. An Oxford-led team reported in Nature Astronomy that the planet's surface is a permanent magma ocean, breaking existing classifications.
