A Planet Slammed Into Earth 4.5 Billion Years Ago, Forming the Moon. The Projectile May Have Been Our Neighbor
Around 4.5 billion years ago, a planet called Theia is thought to have smashed into newborn Earth. The messy collision kicked ...
Theia, the world that helped form the Moon, came from the Solar System. Chemical clues in Earth and Moon rocks reveal this ...
The Moon is not, in fact, a giant cosmic wheel of Gouda. In a landmark paper published in Nature, researchers from the French National Center of Scientific Research delivered a hard truth: the Moon is ...
New research suggests that Theia, the object whose collision with Earth is theorized to have caused the formation of the moon ...
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 ...
Today, the basic physics of getting to the moon and back seem disarmingly simple. Apply the force of rocket thrust to oppose the force of Earth’s gravity, using it to lift off the ground. Apply ...
