To our best of our understanding, the Moon formed from Earth following a colossal impact. A Mars-sized world we nicknamed Theia slammed and merged with the primordial Earth, throwing material into space. Some fell back onto the planet, while some spread ...

If NASA’s ambitious lunar exploration plans succeed, scientists will cover the moon with sensors—and find answers to several long-standing questions about the inner solar system

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 setting, a Mars-sized body called Theia likely struck ...

HONOLULU (KHON2) — 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. It suggests that part of an ancient world may ...

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 interesting than we thought — with big implications for ...

Earth and the moon may look very different today, but they formed under similar conditions in space. In fact, a dominant hypothesis says that the early Earth was hit by a Mars-sized object, and it was this giant impact that spun off material to form the moon.

Whether it’s under the stars on the Main Green, from smudged dorm windows or through open sunroofs, we see the moon nearly every night. But a new study by Brown researchers suggests that we know less about the formation of this familiar celestial sight ...
