Webb Pulls Back the Dust on NGC 7129

A stellar nursery 3,300 light-years away is finally visible — and it's a chaos of jets, shocks, and newborn stars.

[1][2] Webb's infrared sensitivity pierces through the dense matter that scatters or absorbs other types of light, exposing a region teeming with stellar objects at wildly different life stages. [2]

The most massive (and the most mature) is the region's luminous central star, LkH(alpha) 234, weighing around 5 to 8 times the mass of our Sun. [1][2] A gold cavity stretching about 3.5 light-years to its left marks where outflows from an earlier stage of the star's life cycle carve into the dense molecular cloud of hydrogen. [1] That displaced gas isn't wasted: a large amount is compressed, creating the conditions for even more stars to form. [2]

[2] Multiple outflows from multiple stars overlap from our point of view, leading to the scene's chaotic look. [2]

Star birth has always been violent, but it has rarely looked this legible — each color a different act in the same long drama.
