Widespread Turbulence is Upsetting Star Formation in Stephan’s Quintet

This JWST mosaic of Stephan's Quintet is a composite of almost 1,000 images. While it's a visual quintet, only four of them are in the same compact group. Astronomers recently created a high-resolution map of the movement of star-forming gas in the group. Image Credit: NASA, ESA, CSA, STScI

Stephan’s Quintet contains the most well-studied compact galaxy group. Japanese researchers have mapped star forming gas in the Quintet, along with its turbulence. The results show that the Quintet is an evolved group of interacting galaxies where gas struggles to settle down and form stars. Even where gas is concentrated, turbulence from interactions throttles star formation.
