Scientists cannot take pictures of our whole universe, but we can take pictures of what we can see to extreme distance using radio telescopy. I Highly recommend that you watch this video:


Astronomers and scientists alike are able to pick up radio waves in space (that is emitted by stars, galaxies, etc.) and transform it into a coloured image by giving different wavelengths specific colours.
