Debris from the most spectacular explosion could explain the puzzling behavior of comets

Debris from the most spectacular comet explosion of all time is visible from Earth this month and astronomers are hoping observations could shed some light on the puzzling event that lit up the skies in 2007.

When the fainting Comet 17P/Holmes erupted with the brightest cometary burst ever observed in October 2007, astronomers watched in awe. It was not the first time that this disappointing 2.1 mile wide (3.4 kilometer) course comet did it. In fact, the ice ball was only discovered thanks to a similar explosion in 1892.
