The Flaming Star

The Flaming Star

This is a false-color image of the star AE Aurigae (bright source of light near the center of image) embedded in a region of space containing smoke-like filaments of carbon-rich dust grains. Such dust might be hiding deuterium, an isotope of hydrogen, and stymieing astronomers' efforts to study star and galaxy formation. NASA's Far Ultraviolet Spectroscopic Explorer (FUSE) satellite has surveyed the local deuterium concentration in the galaxy and found far more than expected. Because deuterium is a tracer of star and galaxy evolution, this discovery has the potential to radically alter theories about how stars and galaxies form.

Poets might say that the stars are forever, but scientists know that's not true. All star eventually die when they run out of fuel.
   You might think a more massive stars would live longer because it has more fuel to burn. But the heavier a stars is, the faster it burns through its fuel, and the shorter its lifetime is. The most massive stars will live for only a few million years, while the smallest can live for trillion of years.
    All stars spend most of their lives fusing hydrogen ans turning it into helium in their cores. This nuclear fusion creates the energy we see as starlight. Eventually, the stars core runs out of hydrogen. This is the end for low-mass stars like the sun.   When higher-mass stars run out of hydrogen, they can start fusing the helium in their cores, creating carbon and oxygen. The largest stars can keep fusing heavier and hevier elements until their core is full of hot. That's when the stars dies, because no energy comes from fusing iron.
