Gif of star cluster G286.21+0.17

Caption

This animated gif shows the structure and motions (speed in direction towards the Sun) of gas in the forming cluster, as seen with ALMA (purple) on top of the infrared Hubble image. The color-scales from pink-purple to blue-purple represent the gas moving at different velocities, from 15km/s to 24 km/s. These motions are controlled by gravity, turbulence and wind and radiation pressure "feedback" from the new-born stars.
