Next Question
53. How are stars created?
A new star forms when a huge cloud
(made of hydrogen and other
matter) collapses in space.
Gravity at the center of the new star
creates great heat.
Next Question Back to About Stars
54. How do stars produce
energy?
The intense heat inside a star
causes the hydrogen protons to
move so rapidly that they join
together or fuse.
