"During the early solar system's game of cosmic billiards, Earth was struck by a neighbor,” said Dauphas. “It was a lucky shot. Without the moon's steadying influence on our planet's tilt, the climate ...

Research into the formation of the moon was conducted by scientists at the Weizmann Institute of Science in Rehovot, Israel and the Technion-Israel Institute of Technology located in Haifa. Results of ...

The story of how the Moon came to be has always carried a touch of mystery. Picture the young Solar System as a restless place where new worlds grew from swirling gas, dust, and rock. In that chaotic ...

In A Nutshell Inner Solar System origins: By measuring iron isotopes in Moon rocks and meteorites, researchers determined ...

Discover how scientists have used iron isotopes to determine the likely origin of the Mars-sized planet named Theia.

New research suggests that Theia, the object whose collision with Earth is theorized to have caused the formation of the moon ...

Over 4.6 billion years ago, Earth took shape from a spinning cloud of dust and gas surrounding the young sun. Tiny particles within this cloud collided and clumped together, driven by gravity and ...

Scientists continue to explore the deep story of how Earth and the moon formed. One idea has gained attention because it pushes us to imagine the planet in its earliest and wildest days.

The moon was formed 4.5 billion years ago in a "giant impact" that left Earth with a two-hour day, according to new research. Scientists have long debated the circumstances which led to the formation ...

The moon's orbit isn't a perfect circle. Instead, it's more stretched out, kind of like an oval, which means its distance from Earth varies by about 30,000 miles (48,000 km). The surface of the moon ...

The largest and oldest crater on the moon did not form as we initially suspected, a new study suggests. The findings hint that a specific region of the lunar surface could be more scientifically ...
