Scientists are speculating whether ISON, a comet that has spent 4.5 billion years at the edge of the solar system, will implode from the heat of strafing the sun on Thursday. Astronomers call ISON a relic from when our solar system was formed, adding that it has been travelling to meet the Sun for over a million years, and will only ever be seen once in history. This “comet of the century” is expected to provide clues on the formation of the planets.
