Located about 2000 light years away in the constellation Lepus is planetary nebula IC 418. A planetary nebula is a star that’s entered into the final stage of its life. This particular one is also known as the Spirograph Nebula because of its pattern, which resembles a geometric pattern created by a spirograph. Not much is known about the patterns themselves but while they are working toward a better understanding, we can enjoy its beauty.

As we know, a planetary nebula forms after a star has burned through most of its fuel and begins to grow into a red giant, thousands of years pass and the star then begins to release its outer layers of material into the cosmos where they quickly expand and begin the planetary phase. With the stars outer layers now gone, all that’s left is the incredibly hot inner core of the star, and that core now unabated by its outer shell floods the surrounding area with ultraviolet radiation (light) causing the surrounding stellar material to fluoresce. Eventually, the material will fade and all that will remain is a white dwarf star to remind us of what once was.

  1. I always spent my half an hour to read this weblog’s articles every day along with a cup of coffee.

  2. This design is wicked! You most certainly know how to keep a reader entertained.
    Between your wit and your videos, I was almost moved to
    start my own blog (well, almost…HaHa!) Excellent job. I really loved what you had
    to say, and more than that, how you presented it.
    Too cool!
