Visualisation of a galaxy undergoing ram pressure stripping

This visualisation shows a jellyfish galaxy in the three-dimensional view of the MUSE instrument on ESO's Very Large Telescope. This combines the normal two-dimensional view with the third dimension of wavelength. This galaxy has undergone ram pressure stripping as it moves rapidly into the hot gas in a galaxy cluster, and streamers of gas and young stars are trailing behind it. These show up as the tentacles extending away from the galaxy as they have different velocities.

A 3D interactive view of this galaxy is available.
