The Violent End Stage of Star Formation

EsoCast showcases a new Hubble image of a giant cloud of hydrogen gas illuminated by a bright young star. The image shows how violent the end stages of the star formation process can be, with the young object shaking up its stellar nursery.

A few thousand light-years away, in the constellation of Cygnus, lies the compact star-forming region Sh 2-106, or S106 for short. Despite the celestial colors of this picture, there is nothing peaceful about this scene. A young star, named S106 IR, is being born at the heart of the nebula. In the violent final stages of its formation, the star is ejecting material at high speed, violently disrupting the gas and dust. 3D visualizations show the extent to which the star has carved its surroundings into a complex shape. In particular, the hourglass-like structure of the nebula is a result of jets from the star slamming into the cloud of hydrogen it is forming from.

At the outer edges of these cavities, the gas has been compressed into shock f...
