Widespread Turbulence is Upsetting Star Formation in Stephan's Quintet

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.
