SUMMARY: Astronomers used to believe that comets were relics of an early solar system, largely unchanged since the time they were created billions of years ago. But a new study from the Southwest Research Institute indicates that comets might not have had it so easy. Over the course of billions of years, they've been bathed in many kinds of radiation; sandblasted by interstellar dust; heated by stars and supernovae; and fragmented by many collisions. Deep core drilling will probably be necessary to get more realistic data about the state of the early solar system.

The resaerchers know nothing of comets. They think they know where and what they're here for but they have been around since the birth of the galaxy.
