In the previous episode #13, we looked at what happens when three spheres—planets, soap bubbles, and water droplets—collide. This time, we will look at planetary collisions, specifically the theory ...
Known as the giant-impact hypothesis, this proposed event involves a collision between Earth and a hypothetical Mars-sized protoplanet astronomers call Theia.
About 4.5 billion years ago, the most momentous event in the history of Earth occurred: a huge celestial body called Theia collided with the young Earth. How the collision unfolded and what exactly ...

The moon may have formed through Earth’s collision with close neighbor, a new study finds. One bright day on Earth about 4.5 billion years ago, everything changed. A massive object slammed into the ...
Earth’s unusually large Moon may not have assembled gradually from a vast ring of debris after all. Under the right conditions, much of it could have emerged as an intact body only hours after another ...
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 ...
A new study has determined with 99.9% accuracy that the Moon was formed 95 million years after the birth of the Solar System. This pegs the Moon as being a lot younger than we previously thought -- ...
New clues to the origin of the Moon surfaced this week, which reveal that the Earth and Moon are not as similar as previously thought, and part of the protoplanet that helped create the Moon may still ...
