Here's how interstellar objects and rogue planets can be trapped in the solar system

When 'Oumuamua traversed our solar system in 2017 it was the first confirmed Interstellar Object (ISO) to do so. Then in 2019, Comet 2l/Borisov did the same thing. These are the only two confirmed ISOs to visit our solar ...

New lunar map can help guide future sample return missions

Billions of years ago, a giant asteroid struck the moon with so much energy that it melted rock until it was super-heated and white-hot, or what scientists call impact melt. This eventually cooled and hardened, creating a ...
