Question

Arrange the events in the life of a star in the correct order.

All that remains of the star now is the core. In some cases, the star turns into a black hole.

As the nuclear fusion sets off a chain reaction, the nebula gets hotter and brighter and turns into a star.

The star stays in the main sequence stage for a long time.

The star runs out of hydrogen and turns into a planetary nebula or a supernova, depending on its mass.

Heavy elements are created when the supernova explodes.

The temperature increases in the center of a nebula, and nuclei begin to fuse.
