Define a supernova and a neutron star. What is the key difference between them?.
Model answer
What a good answer should say
- A supernova is a powerful explosion that occurs at the end of a massive star's life cycle, resulting in a dramatic increase in brightness.
- A neutron star is the remnant core left after a supernova explosion, composed almost entirely of neutrons.
- The key difference is that a supernova is an explosive event, while a neutron star is a stable, dense object formed from the remnants of that explosion.
Explanation
Why this works
This answer effectively defines both concepts and highlights the key difference between a supernova and a neutron star. It explains that a supernova is an event, whereas a neutron star is a resultant object, providing clarity on their relationship in stellar evolution.
