Cropped, close-up, near-infrared image of the exposed cranium nebula from the James Webb Space Telescope, highlighting the core dusty orange region. Some of the whitish outer edge bubble of the nebula and background stars can also be seen.

Summary

The telescope used two instruments to capture mind-bending new views of the little-known nebula PMR 1.

Astronomers are losing their heads over the latest images from NASA’s James Webb Space Telescope, which bear a striking resemblance to a transparent cosmic cranium, revealing the “brain” inside. The nebula, officially named PMR 1, is being created by an aging star that is expelling its outer layers. Webb’s predecessor in infrared space-based astronomy, the now-retired Spitzer Space Telescope, also observed this peculiar nebula, but many of its mysteries remain to be revealed.

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 ...
