The James Webb Space Telescope shows many details of HH211's gas flows. Extended bow shock waves (bottom left and top right) give a glimpse of how the gas jets collide with surrounding material. Inside the extended cocoons lies the source of power: almost inconspicuously, thin jet streams propagate in opposite directions. The point of origin of one or more stars is hidden from the observer in the centre of the brown-black veil of dense gas. This image exceeds the detail of earlier images by about five to ten times.

Before the light comes on and a new star shines, enough gas and dust must accumulate in a very small space for a star’s energy source, nuclear fusion, to ignite. This by no means happens at rest. Matter swirls around, and before the star sees the light of day, violent birth labour is not uncommon. The new James Webb Space Telescope has turned its lens on such a spectacle, which reveals itself in unprecedented detail.

An international team, including researchers from the Max Planck Institute for Astronomy, recently captured a spectacular image of the so-called Herbig-Haro object HH211 in infrared light with the James Webb Space Telescope. ...
