SPACE — To the naked eye, the stars in the night sky look very similar to each other, the main difference between them being that some are brighter than others. However, if we look more closely, the stars have different colors. Apparently, there is a blue star.
Most stars look white. However, some have a distinctive red color while others are blue. Blue stars are the largest and brightest stars in the galaxy.
Reporting from Space, the color of the star tells us about the temperature and mass of the star. Blue stars are the hottest and most massive.
Any star that has three or more times the mass of the sun tends to appear blue to our eyes. This does not depend on other factors such as chemical composition. Blue, yellow, and red stars together consist of about 75% hydrogen, 24% helium, and small amounts of other elements.
However, the fact is that blue stars are more massive. This means that blue stars generally have a higher intrinsic luminosity than other stars. This means blue stars can be far away in the sky but still visible.
Blue stars are blue because they are very hot. This may sound wrong, because in everyday life, for example on a weather map — red means hot and blue means cold.
However, blue light carries more energy than red light. This means that blue stars require a hotter source of radiation to produce them.
This explains why blue stars are hotter than red stars. Consequences like these can be seen in forged metals.
First, the metal glows red, then as it gets hotter, it turns white-blue.
Blue stars have high temperatures. This means that blue stars are constantly releasing large amounts of energy into space. As a result, blue stars burn all their fuel very quickly, making blue stars the shortest-lived.
Blue stars are most often observed close to the star formation region where they were born.
Although star formation regions produce stars of varying masses, blue stars are not created in equal numbers. Low-mass blue stars far outnumber high-mass ones.
Coupled with the short lifespan of blue stars, this makes blue stars tend to be rare. However, we see quite a lot of blue stars in the night sky, because those that exist are so bright.
