Looking through the telescope, startled to discover "hellish" super Earth
The James Webb Space Telescope has just revealed a "hellish" super Earth with bubbling toxic gases and the ability of volcanic eruptions to create magma oceans in the middle of the universe.

L 98-59 d is a super-Earth just 35 light-years away, orbiting the red dwarf star L 98-59.

(Photo: Science Photo Gallery) The sky of L 98-59 d is filled with sulfur dioxide and hydrogen sulfide – dangerous gases that cannot support life. (Photo: NASA Science) This is the smallest super-Earth whose atmosphere has ever been observed, and also one of the most extreme planets ever recorded.
