The relatively close M83, which is 15 million light years away, is one of the closest spiral galaxies in our neighbourhood. It is half the size of the Milky Way but has a higher rate of star formation. You can see a lot of star clusters with bright blue and relatively young stars (just 1 to 10 million years of age) as well as huge, red emission nebulae. If you want to understand how this galaxy looks with "different eyes" – which means at different wavelengths - you should absolutely read our article about the electromagnetic spectrum. You'll understand a lot more about this galaxy and electromagnetic radiation in general after reading it. A close-up image of the central region taken by the Hubble Space Telescope reveals even more details. Read more about: Emission nebula - Electromagnetic spectrum
