You are looking at one of the most intricately structured and dynamic objects ever observed.
The Crab Nebula is a six-light-year-wide expanding remnant of a star's supernova explosion. Japanese and Chinese astronomers witnessed this violent event nearly 1,000 years ago in 1054.
The colours in the image indicate the different elements that were expelled during the explosion. Blue indicates neutral oxygen, green singly ionised sulphur and red doubly-ionised oxygen.
The size of the universe can not be comprehended by little minds like mine.
