Stellar Core Quotes

What goes on inside a star is better understood than one might guess from the difficulty of having to look at a little dot of light through a telescope, because we can calculate what the atoms in the stars should do in most circumstances.

Now, our Sun will not collapse to a black hole. It's actually not massive enough.

Stars that become supernovae start off at least eight times heavier than our sun. They're so short-lived that, even if they have planets, there is unlikely to be time for life to get started. The surface is 40,000C and, as a result, the colouring will be extremely blue.

The iron from that meteorite and the iron from your blood have common origin in the core of a star.

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.

The sun derives its energy from fusion reactions in which hydrogen is transformed into helium.

At the extreme temperature occurring in the stars, matter can only survive in its most dissociated states. Only simple bodies exist on these incandescent stars.
