High-speed ‘skirmish’

The James Webb Space Telescope has delivered a first of its kind: a crisp mid-infrared image of four coiled shells of dust around a pair of Wolf-Rayet stars known as Apep. Observations taken prior to Webb only detected one shell, and while the existence of outer shells was hypothesized, ground-based telescopes were unable to uncover any. https://science.nasa.gov/missions/webb/webb-first-to-show-4-dust-shells-spiraling-apep-limits-long-orbit/
