Assignment 1: the life of a star
The correct order from the birth of a star to its death:
1. C – In this image the protostar is represented. A protostar is a star that hasn’t yet
reached the fusion stage. A protostar can grow by accretion and collecting mass from
the surrounding substances and gases.
2. D – We see a star represented in this image. The majority of stars in the universe
are in this stage. Also the sun is in the ‘star’ stage. The stars shine as nuclear
reactions inside produce light and heat.
3. B – We see a Red Giant. When a star is in the ‘Red Giant’ stage, the star expands
and glows red as it cools, finally the outer layers of the star are blasting away.
4. A – This is a supernovae. Only the most massive stars become supernovae. What
we see at the image, is the result of an explosion of a star.
The images in the correct order:
