Phys.org / Webb reveals Apep's four 'spiraling' dust shells shaped by Wolf-Rayet stars

NASA's James Webb Space Telescope has delivered a first of its kind: a crisp mid-infrared image of a system of four serpentine spirals of dust, one expanding beyond the next in precisely the same pattern. (The fourth is almost ...
