Latest Late Heavy Bombardment Stories
Over four billion years ago, giant asteroid impacts collided with the Earth’s surface and gave the planet a facelift of sorts – mixing, burying and melting the landscape, according to a new terrestrial bombardment model devised by an international team of researchers.
Earth was irrevocably changed when the dinosaurs were wiped out about 65 million years ago by a massive asteroid, but a much bigger asteroid that struck the Earth nearly 3.3 billion years ago is thought to have shaped parts of Africa.
Scientists have long believed that the moon’s trademark craters were created from the impact of massive asteroids, but new research suggests that smaller planetoids might actually have been responsible for pummeling the lunar surface.
Scientists from NASA’s Lunar Science Institute (NLSI), along with researchers from abroad, have discovered that Earth’s own natural satellite shares a striking similarity with Vesta, and perhaps other large asteroids roaming around the Solar System.
Bombardments of 'micro-meteorites' on Earth and Mars 4 billion years ago may have caused the planets' climates to cool dramatically.
The study shows that the comets were probably captured 600 million years after the formation of the solar system, during the Late Heavy Bombardment
British scientists say large bombardments of meteorites four billion years ago might have made early Earth and Mars more habitable for life. Imperial College London researchers said millions of meteor strikes during what's called the Late Heavy Bombardment approximately 3.9 billion years pelted Earth
Large bombardments of meteorites approximately four billion years ago could have helped to make the early Earth and Mars more habitable for life by modifying their atmospheres.
WASHINGTON, May 20 /PRNewswire-USNewswire/ -- A NASA-funded study indicates that an intense asteroid bombardment nearly 4 billion years ago may not have sterilized the early Earth as completely as previously thought.
