Exposed Cranium Nebula (NIRCam and MIRI Images)
The differences in what Webb’s infrared instruments reveal and conceal within the PMR 1 “Exposed Cranium” nebula is apparent in this side-by-side view. More stars and background galaxies shine through the view of Webb’s NIRCam (Near-Infrared Camera), while cosmic dust glows more prominently in the light captured by MIRI (Mid-Infrared Instrument).
The dark center lane that contributes to this nebula’s distinctive brain-like appearance is more noticeable in NIRCam, but its apparent role in the ejection of material at the top and bottom of the nebula is seen more clearly in MIRI’s view. Observing the cosmos in various wavelengths of light provides a more complete picture of how the universe works.
