Question

Which type of star death causes elements to travel into space?

a planetary nebula

a black hole

a pulsar

a supernova

Answer 1

The type of star death that causes elements to travel into space is a **supernova**. During a supernova explosion, a massive star expels its outer layers into space, enriching the surrounding interstellar medium with heavy elements formed during its lifecycle. While a planetary nebula also ejects material into space, it specifically pertains to the death of medium-sized stars (like our Sun) and primarily consists of lighter elements.
