Blue stars shine blue because of the energy that they are radiating.
Blue is a higher (more energetic) wavelength of the visible spectrum of electromagnetic radiation.
Blue stars have much more energy associated with them, therefore, the majority of the light that they release is in the higher spectrum...blue light.

∙ 8y agoThe more mass a star has the faster it fuses its hydrogen fuel. Faster burning of fuel means more energy is released and so results in higher temperatures. The hotter a star is the shorter of wavelength it emits. Blue light has a shorter wavelength than other colors and so the hottest stars appear blue.

Imagine heating an iron bar. It starts off going red, then orange, yellow and if you heat it long enough it will go white.

The color of a star comes from its temperature. The coolest stars appear red, while the hottest stars are blue. And for a star, the only thing that defines the temperature of a star is its mass. Blue stars are stars that have at least 3 times the mass of the Sun and up. Whether a star has 10 times the mass of the Sun or 150 solar masses, it's going to appear blue to our eyes.

Yes, they can appear blue, as well as other colors.

Trust me, you wouldn't wanna' try somthing like that!

∙ 13y agoSimply they are bigger - they have more mass. Because they are so massive, more pressure is generated in the core, this produces more fusion, which produces more heat.
Wiki User
∙ 10y agoThe color of a star depends on its surface temperature - the surface being the visible part. Hotter stars are blue.

∙ 8y agoNo. A blue star gives off all wavelengths of light. It just emits blue light more than any other color.
