All the Colors of the Stars

Stars appear mostly white to our naked eye in the night sky.
Sometimes maybe a little red or yellow. But only faintly. In
reality however, stars are as colorful as a rainbow! And their
colors tell us a lot about the properties of each individual
star, like a calling card. Their age, size, temperature, past and
sometimes even their future is encoded in their chromatic
appearance.  Paul sets out with you on a tour of the colors
of the night sky, through red, yellow, blue and more!
