Cosmic Thoughts – Light

The lights we see from stars and planets emit a beautiful array of colours. But light isn’t just about illumination. Light is the very DNA of a celestial body’s chemical make-up. By using spectroscopy, astronomers can deduce what elements are present on a planet or star. Each and every element in the universe, when burned, gives off a unique set of colours. And these are the same anywhere across the vast universe. Strontium is a reddish purple. Sodium is yellow. Potassium is lilac. Copper is blue. And so on.

If you look at a rainbow, you are also looking at the chemical make-up of our own sun. Our sun is about 70% hydrogen and 28% helium – which isn’t surprising, because those two are the most common elements in the universe. And as you can imagine, for a painter, knowing that colours play such an important role in the decoding of the universe – colours are essentially the bar codes of existence – is a great inspiration. So when you look at the night sky, and you paint it, you pay very careful attention as to what each and every colour you’re using actually means.

Colour then, is the language of the universe. The phrase ‘the music of the spheres’ should be redundant – the universe is quiet, but it has some very loud colours!
