If you look closely at the night sky, you’ll notice that stars come in a variety of shapes and sizes.
If the wavelengths of a star were plotted on a chart, they would make a bell-shaped curve, with cooler stars peaking at red on one side of the graph and hotter stars peaking at blue on the other end.
So where do green stars fit in? Stars of medium heat mostly emit green photons, but they don’t appear green.
