Hello and welcome to my blog about my life (science) and whatever else takes my fancy (hint: it's more science). You may call me Dougal and I'm 19 Earth years old, currently double majoring in physics and chemistry in New Zealand. In reality I have no idea what I'm doing or what I'm going to do though so you'll find a little bit of everything.
The Hertzspring-Russell Diagram is a chart that shows the relationship between luminosity and colour of stars. The chart itself contains information for about 23,000 nearby stars and illustrates the fact that stars only fall within certain allowed regions of the diagram.
