... Spectral type – Indicates the color of the star, which is related to its surface temperature. From the hottest to coolest, also from blue to red color, the types are: O, B, A, F, G, K, M. A second number is added for finer classification, like G0, G1, G2, …, G9. A blue star is hotter than a yellow s ...

... Supergiants are the largest and brightest stars in the galaxy. Red supergiants are larger than blue ones, but less hot. When a large star runs out of hydrogen to fuse, it expands to become a red giant. When it reaches the stage of burning helium to carbon, it expands and become a red supergiant. Thr ...
