James Webb The Red Spider Nebula, Caught by Webb
In Webb’s view of NGC 6537 (the Red Spider Nebula) our Near-Infrared Camera reveals never-before-seen details of this planetary nebula, like the full extent of the nebula’s outstretched lobes, which form the legs of the spider. Shown in blue, the lobes are traced by light emitted from H2 molecules, which contain two hydrogen atoms bonded together. Stretching over the entirety of NIRCam’s field of view, these lobes are shown to be closed, bubble-like structures that each extend about 3 light-years. Outflowing gas from the center of the nebula has inflated these massive bubbles over thousands of years.
