Guided Exploration: Stars Zone

Part of Hall of the Universe.

 

A schematic drawing of the Hall of the Universe in the Museum's Rose Center for Earth and Space.

Overview: A star is a huge luminous ball of hot gas, mostly hydrogen and helium, held together by gravity. Nuclear reactions in the cores of all stars, including our Sun, produce energy in the form of light. Stars shine because this light works its way to the surface and radiates out into space. This zone explores the various types of stars, their life cycles, and how stars produce the building blocks of life.
