03-Hubble's Final Frontier 哈勃的最终领域

Hubble's image of Carina shows a region over 50 light-years across.

Here too are the EGGs that will one day become stars encircled by planets.

Among the thousands of newborn stars lurks a surprise.

Within the cloudy halls of Carina, Hubble detects the death throes of a massive star.

For scientists, a dying star is an opportunity to see the future of our own solar system.

What these Hubble images show are shells of gas that serve as tombstones. Their quiet beauty is deceptive.

These walls of color are the outer layers of a star much like our sun.

As a star runs out of fuel, these layers expand, until the gravity of the star can no longer hold them.

Eventually, they are released into space In 2004, Hubble captures an image that gives us a glimpse of our eventual demise. The Helix Nebula.

As these outer layers of a star expand, they leave behind a searing hot ball of solidified oxygen and carbon, astronomers call a "white dwarf".
