Webb watches carbon-rich dust shells form and expand in star system
- The James Webb Space Telescope has observed carbon-rich dust shells forming and expanding in the Wolf-Rayet 140 star system, which is about 5,000 light-years from Earth.
- A study presented at the American Astronomical Society conference revealed that the dust shells are moving outward at over 1,600 miles per second.
- The little red dots observed by the telescope are thought to be a common feature of the early universe, appearing around 600 million years after the Big Bang.
- Researchers indicate that these observations could provide insights into the formation of galaxies and black holes.

The Webb Shows Us Where Cosmic Dust Comes From
Carbon-rich cosmic dust comes from different sources and spreads out into space, where it’s necessary for life and for the formation of rocky planets like ours. When astronomers aim their telescopes at objects in the sky, they often have to contend with this cosmic dust that obscures their targets and confounds their observations. One reason the JWST was built is to see through some of this dust with its infrared vision and unlock new insights i…
