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.
