The color of a star gives information about its temperature and mass.
REPUBLIKA.CO.ID, JAKARTA – When viewed with the naked eye, the stars in the night sky all look very similar to each other. The main difference is that some stars appear brighter than others.
However, jIf you look closely, the stars have different colors.
Most of the stars appear white. However, there are actually red and blue ones. The color of a star tells us of its temperature and mass. Blue stars are the hottest and most massive of all star types.
Blue stars are by far the largest and brightest stars in the galaxy. Reported by Spaceany star that has a mass three or more times that of the sun will tend to appear blue to our eyes.
This condition is independent of other factors such as chemical composition. Blue stars, yellow stars, and red stars are both made up of about 75% hydrogen, 24% helium, and small amounts of other elements.
The following are the facts of the blue star
Why are blue stars so hot? Blue stars are blue because they are very hot. Blue light carries more energy than red light, which means it requires a warmer radiation source to produce it.
This explains why blue stars are hotter than red stars. The analogy is similar when looking at the heated metal in a workshop. At first, the metal glows red, then as it gets warmer it becomes blue-white.
