Creating the star cluster NGC 3532

The MPG/ESO 2.2-metre telescope at ESO’s La Silla Observatory in Chile captured this richly colourful view of the bright star cluster NGC 3532. Here can be seen something of the process of creating such a striking image. The cluster is photographed separately through three colour filters, one recording blue light, one recording green light and one recording red light. Combining the three images produces the natural colours of the final image. This enables us to see clearly the different types of star in the cluster. Some of the stars shine with a hot bluish colour, but many of the more massive ones have become red giants and glow with a rich orange hue.

This image forms part of the Living Universe exhibition in ESO'\s Supernova Planetarium & Visitor Centre.
