Stellar Lifecycle Quotes

We are made of star stuff. For the most part, atoms heavier than hydrogen were created in the interiors of stars and then expelled into space to be incorporated into later stars. The Sun is probably a third generation star.

Once a star dies, it's gone forever. There are no new stars to take its place. Eventually, there will be no stars, and the universe will turn black. That really will be the end.

Very, very slowly, the dwarf remnants of what was once our mighty sun will cool and dim, until it embarks on its final metamorphosis, gradually solidifying into a crystal of extraordinary rigidity. Eventually it will fade out completely, merging quietly into the blackness of space.

Stars have their moments then they die.

An ordinary black hole is thought to be the end state of a really massive star's life.

Many billions of years will elapse before the smallest, youngest stars complete their nuclear burning and shrink into white dwarfs. But with slow, agonizing finality perpetual night will surely fall.

Most stars just fuse hydrogen into helium, but larger stars can fuse helium into other elements. Still larger stars, in turn, fuse those elements into slightly bigger ones, and so on.

The objects that are of moderate energy, like our sun or most of the stars that we see in the night sky with the naked eye, are objects in which relatively moderate energy processes are taking place.

We forget how recently astronomers figured out what the stars are made of, what makes them shine, how distant they are, how they are born, and whether they remain immutable or evolve and die.

What do stars do? They shine.

When the Sun shrinks to a dull red dwarf, it will not be dying. It will just be starting to live and everything that has gone before will merely be a prelude to its real history.
