ALMA Mosaic Star Cluster (animated gif)
This animated gif shows the structure and motions (speed in direction towards the Sun) of gas in the forming cluster G286.21+0.17, 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.
