All stars are hot. Blue stars are the hottest. The hotter a star is, the shorter the wavelength of light it emits. Blue light has a shorter wavelengths than most other colors.
It relates to how hot it is because if it was blue it would be a hotstar and it it was red it would be a cool star!
No, it is blue (very hot). Betelgeuse, also in the constellation of Orion, is red.
If the star is a bright blue-whit color then the star is hot....but if its red, or a color that's close top red then the it isn't hot, but its not cold either....its just not as hot as the blue-white star is. You can also find this information and more in the Kelvin Scale below.
It supernovas, and it's collective particles are commonly called a blue waffle
A red star is cooler and has a lower temperature compared to a blue star, which is hotter. Red stars are typically older, while blue stars are younger. The color of a star is determined by its surface temperature, so these differences in characteristics between red and blue stars are consistent.
The blue star is the hottest star.
A red star is cool whereas a blue star is hot.

If a blue star wasn't so hot - it wouldn't be a blue star - it would be a white star.See related question for more details.

Star colors tell us how hot the star is. For example a red colored star is cool and a blue colored star is hot.
a blue star is hotter then a red star because it is younger and thus has more energy. a good example of this is when you look at a flame on a lighter you see blue light at the bottom because blue is hottest and closest to the heat source whereas the red-orange flame at the top is farther away from the heat source and thus is not as hot as the blue.
How hot or cool a star is. For example if a star is red, it's cooler. If a star is more blue, it's hotter.
A star's color tell us how old the star is and how hot the star is. A blue star is very hot and is young, a yellow star is cooler than blue, but hotter than red and is about half way through its lifetime, lastly a red start is cooler than yellow and blue and is near the end of it's life. submitted by: Fabrigar, Lovely Joana Ymas.

Rigel is a blue-white star wich indicates that is a very hot star. you might think red stars are the hottest but no, the hottest are blue-white.
