Album Info:
The colorful planetary nebula phase of a sun-like star's life is brief. Almost in the "blink of an eye" - cosmically speaking - the star's outer layers are cast off, forming an expanding emission nebula. This nebula lasts perhaps 10 thousand years compared to a 10 billion year stellar life span. Spectacular planetary nebulae are familiar objects to both professional and amateur astronomers.

Star gazing is one of my most favorite things. To even see that there's wonders of such in space makes you just wonder what else is out there. This is Great!! Thanks
