  • Two heads are better than one in the latest images from NASA’s James Webb Space Telescope, which reveal new detail in a mysterious, little-studied nebula surrounding a dying star. Nebula PMR 1 is a cloud of gas and dust that bears an uncanny resemblance to a brain in a transparent skull, inspiring its nickname, the “Exposed Cranium” nebula. Webb captured its unusual features in both near- and mid-infrared light. The nebula was first revealed in infrared light by a predecessor to Webb, NASA’s now-retired Spitzer Space Telescope, more than a decade ago. Webb’s advanced instruments show detail th
