The scientists calculated that the collision occurred about Feb. 10, 2009. The discovery of the relatively recent event is a rare treat for astronomers, who study events from eons ago. Astronomers peer into the past. They observe galaxies forming millions of years after the fact. They hunt for traces of water that flowed eons ago on moons and other planets.
