The James Webb Space Telescope may offer a solution to the enigma of enigmatic signals emanating from the distant “hell planet” located 40 light-years away from Earth.

This illustration shows one possible scenario for the hot, rocky exoplanet called 55 Cancri e, which is nearly two times as wide as Earth. New data from NASA Spitzer Space Telescope show that the planet has extreme temperature swings. (Image credit: NASA/JPL-Caltech)
