Astronomy for Beginners: The Dying Star

An extremely bright star (outshining even the Sun) is called 'a supernova', meaning 'super' and 'novel'.

A supernova is short-lived.

It is bright because it is dying in a vast explosion, which we cannot help noticing.

After exploding, it runs out of energy and becomes what we scientists call 'a remnant of degenerate matter'.

Finally, the star collapses and dies, becoming 'a black hole' which sucks everything in its vicinity into itself with an irresistible and destructive force.

And so the degenerate remnant of the briefly-bright star destroys everything unfortunate enough to get too close to it.

I think that's how it works. Roughly.

  1. Mr. P,

    Linked to your story with the comment that I think you meant a 'brown' hole?

    Just thought I'd arse(k).

  2. Many thanks for the link, WfW. Most kind.

    People perceive black holes according to their particular receptivity to the emissions from different dying stars. Yes, brown, maybe, or jade.
