Stars were once regarded as eternal.
|
|
But since astronomers used telescopes to study the stars a few centuries ago, they discovered the spectrum of stars and gradually unveiled the physical properties of stars. It is now established that stars evolve and go through a cycle of birth and death.

Comparing with other scientists, astronomers face greater difficulties in that they cannot perform experiments on the stars in their laboratories. They can only observe the stars at a distance and develop new theories based on the observations.
|
|
In recent decades, with rapid development in space science and computer technologies, astronomers discovered many new and exotic celestial objects. Some celestial objects like supernova 1987A can help to reinforce the theory of stellar evolution. But others such as gamma ray sources pose more headaches and sometimes conflicting theories.

After the supernova SN1987A exploded for more than a decade, the surrounding gas ring gradually brightened up. The bright spots are believed to have formed as shock waves from the explosion clashed with the gas ring and heat it up.

The new sky show "Bizarre Celestial Objects" will take a closer look at these amazing celestial objects. |

the cooler dust in the Elephant Trunk Nebula
to reveal the luminous proto stars behind.
