Estimates place it at 3.8 billion years old, compared to the oldest impact basin, the South Pole-Aitken basin, which has been calculated to be over 4.3 billion years old.

THE IMBRIUM BASIN The Imbrium basin is one of the largest known impact sites in the solar system. It was formed 3.6 billion years ago when an asteroid smashed into the moon.

Piecing together an ancient impact Canyons and ravines created by streaks of rocky debris radiate from Schrödinger basin. Lunar geologists have always known that the two canyons featured in the ...

A view of the moon's largest impact feature, the South Pole-Aitken basin. This region stretches between Aitken crater and the south pole (hence the name).

New research indicates that these canyons, in an area called the Schrödinger impact basin on the side of the moon perpetually facing away from Earth, were dug out in a matter of less than 10 ...

According to the researchers, the 1,160-kilometer-wide Imbrium basin, along with the main rock in the meteorite, formed when an asteroid struck the moon 3.909 billion years ago.

It was even more devastating than the impact which killed off dinosaurs 65 million years ago. New research shows a massive 155 mile (250km) wide basin which exhibits all the signs of a cavity ...
