Our own Galaxy is interesting in all parts of the electromagnetic spectrum. With
our eyes we can see many clusters of stars and the dust lanes that run through the
disk. The dust is warm and so shines brightly at infra-red wavelengths, while we
can look straight through it with radio telescopes, peering right into the heart of
our Galaxy.
This map shows the Galaxy as seen by radio telescopes. Observations were made using telescopes at Bonn in Germany, Jodrell Bank in the UK, and Parkes in Australia, and the results were combined to create this full-sky map. Radio waves allow us to probe the centre of the Galaxy in regions where dust blocks out ordinary visible light.
