Scientists have long sought to determine the age of the moon's South Pole–Aitken (SPA) basin, the largest and oldest known ...

is that the moon formed during a giant impact between the proto-Earth, and another protoplanet roughly the size of Mars, sometimes called “Theia.” In this theory, the moon formed from the impact ...

A major breakthrough in space science has revealed the age of the Moon’s biggest and oldest crater—the South Pole–Aitken (SPA ...

The leading explanation for all of these mysteries is known as the giant impact hypothesis. According to this story, when the ...

judging by meteor impact craters, were significantly younger than the surrounding region, suggesting a more recent formation than expected. "Many scientists believe that most of the Moon's ...

The accretion hypothesis proposes that the Moon was created along with Earth at its formation. The fission theory suggests Earth had been spinning so fast that some material broke away and began to ...

the Moon formed a crust and a mantle below. Giant pools of lava filled impact craters and settled into the lunar lowlands, or maria (Latin for “seas”), while highlands and volcanic domes ...

A new map of the moon’s Mare Orientale basin highlights areas containing original impact melt. These findings could help date the basin’s formation, which is estimated to be 3.8 billion years old.

Scientists are revisiting the age-old question of how Earth's moon formed with the development of two new models that work out the complicated physics of planetary collisions. The idea of a ...

(CNN) — About 3.8 billion years ago, two massive canyons likely formed on the ... larger Schrödinger impact basin, where an object yet to be identified slammed into the moon billions of years ...

In a paper published in National Science Review, a research team from the Chinese Academy of Sciences investigated impact ...
