The Sculptor Galaxy in a Myriad of Colors | European Southern Observatory
This animation shows the depth of information that is contained in a new portrait of the Sculptor galaxy. While a normal image contains information in just a handful of colors, here we see the Sculptor Galaxy in thousands of them.
The data were captured with the Multi Unit Spectroscopic Explorer (MUSE) instrument on the European Southern Observatory's Very Large Telescope (VLT). As the video goes through colors (or wavelengths), the galaxy lights up as we see the specific color emitted by certain elements such as hydrogen, oxygen, sulphur or nitrogen. We also see one side of the galaxy light up before the other. This is due to the Doppler effect: as the galaxy rotates, one side of the galaxy is moving towards us, and its light is shifted to bluer wavelengths, whereas the light from the receding side is shifted to redder wavelengths.
