Question

blue stars in space

Answer 1

Blue stars are always young when you compare their age to the age of the universe. Blue stars are larger stars, which burn hotter and therefore more towards the blue part of the spectrum. The smallest stars glow red, because they are cooler. Larger stars, ironically, have shorter lifespans than smaller stars. Although they have a lot more fuel to consume, they consume it at a much faster rate, so paradoxically they die much sooner than a small red star.

All blue stars that are close to us (in our galaxy, for example) are relatively young because they only live for millions or a few billion years, depending on their size. Red dwarf stars can possibly live for up to 100 billion years, by comparison. If you look further out in the universe, you do see more blue stars, because you are looking backward in time and those stars appear to still be burning, even though they may have gone out, exploded or imploded long ago. Depending on their size, the largest stars can simply run out of fuel, explode in a glorious supernova, and/or implode into neutron stars and black holes.

The blue stars live hard and die young, but their deaths create the heavier elements found in the universe. All elements on earth that are more massive than iron were created by the death of a large (and quite possibly blue) star. Our bodies are literally composed of this material that was once part of a star. Blue stars seed the cosmos with heavier elements, and can spawn multiple generations of stars and planets.

Answer 2

There have been several blue stars found that I know about (probably millions or billions). This is not exceptional. Any stars with blue in it's spectrum (every single one) will show up more blue by the time the rays reach earth. Every star you look at in the night sky looks blue. There is nothing to this myth. The hopi people made vague predictions for a reason. Because they can be interpreted to mean almost anything.

Answer 3

All the pictures of new stars i have seen have been reddish due to the evaporating gaseous globules (EGGs) emerging from mounds of molecular hydrogen gas and dust. I am by no means an expert in astrology or astrophysics though, so double check that

Answer 4

Old. Heres some sites

Answer 5

Here's a site on blue giants

Answer 6

Type "star" into the search window of www.wikipedia.org. That link in the answer above looks good too, if you are not an adult.
