BBC Earth - Timeline - The Late Heavy Bombardment and the early Earth

Watch BBC video clips about The Late Heavy Bombardment, a time in the history of the Earth when asteroids and comets peppered the planet.

Late Heavy Bombardment - 'The Late Heavy Bombardment (commonly referred to as the lunar cataclysm, or LHB) is a hypothetical event around 4.1 to 3.8 billion years ago. During this event an extraordinary number of the impact craters on the Moon would have formed, and by inference an extraordinary large number of impacts on Earth...  Extrapolating lunar cratering rates to Earth:   22,000 craters with diameters >20 km,  about 40 > 1,000 km, several > 5,000 km'

New research shows that more than four billion years ago the surface of early Earth was heavily reprocessed as a result of giant asteroid impacts.

The Late Heavy Bombardment (abbreviated LHB and also known as the lunar cataclysm) is a hypothetical event thought to have occurred approximately 4.1 to 3.8 billion years (Ga) ago,[1] corresponding to the Neohadean and Eoarchean eras on Earth. During this interval, a disproportionately large number of asteroids apparently collided with the early terrestrial planets in the inner Solar System, including Mercury, Venus, Earth, and Mars.

Even though the Late Heavy Bombardment is somewhat of a controversial idea, new research has revealed this period of impacts to the Earth-Moon system may h

Lunar scientists shed light on Moon’s impact history Analysis shows that craters formed near the Nectaris impact basin were created by projectiles hitting twice as fast as those found on more ancient.

Incoming! The LHB probably lasted a lot longer than previously thought, with some really big blasts, too.

Late Heavy Bomardment. Migration of giant gas planets such as Jupiter created the biggest meteor storm in our solar system's history, according to a new study. The research in the journal 'Nature Geoscience' paints the clearest picture yet of the causes of the Late Heavy Bombardment, a cosmic tempest 3.9 billion years ago, which shaped the solar system we have today.

I recognise this wonderful old illustration from a late 1960's 'Look & Learn' annual. It's depicting a time long before even the Pre Cambrian when the early Earth & Moon had recently formed & the 'Late Heavy Bombardment' was under way.
