Astronomers solve decades-old mystery of conflicting dust sizes in massive stars
Some stars don’t just shine; they also manufacture the raw ingredients of future worlds.
The binary system Apep has a stack of four nested dust shells around two Wolf-Rayet stars. A third star creates a wedge-shaped gap in the pattern. Credit: NASA / ESA / CSA / Yinuo Han / Ryan White / ...
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 ...
