What is meant by the statement: We are all made from star dust?

• The celebrities of Hollywood are cool role models for us.

• All elements from nuclear fusion make up planet Earth

• Humans are made up of elements originating from events such as nuclear fusion in extinct stars and supernovae in stars that exploded.

• Star dust traveled over cosmic rays to reach us around the time of human evolution.

What is meant by a supernova?

• A situation when nuclear fusion has gone wrong and the star must implode.

• A supernova is a powerful and luminous stellar explosion. This event happens at the beginning of the stars life.

• An event that only happens in small stars.

• A supernova is a powerful and luminous stellar explosion. This event occurs at the end of a massive star's life.
