The Cambrian Explosion is not an explosion in a literal sense; the Cambrian explosion is actually a period in history, from 570-530 million years ago, in which a huge variety of life emerged on planet Earth.  Fossil records determine a rapid introduction of new life during a time in hisotry called the "Cambrian Period."  Many theories have been created to try to determine the sudden boom of life, but many  contridict each other.  New theories are still being created today, and many are controversial to different groups.  The Cambrian Explosion is a very relevant topic because by determining what happened in the past, we can learn about what could possilby occur in our future.

"BIOLOGY'S BIG BANG"
Astrobiology is the search for life outside of our planet.  Many factors determine whether life is present or not on a planet. 

Astrobiology relates to the Cambrian Explosion in the sense that if we are able to determine what the cause of it was, we can look for life in the universe and determine what is needed for a similar event to occur elsewhere in the universe.
