That's unbelievable. 200 meters on a broken fibula. Thanks to his efforts, the team qualified for the next round.



NASA's Voyager 1 is approaching the Heliopause, the boundary between our solar system and interstellar space. It will become the first manmade object to leave our solar system.


The Supermoon happened in early May. It's an astronomical event where a new (or full) Moon coincides with the point in the Moon's elliptical orbit where it is closest to Earth, creating the illusion of a larger-than-normal size, and it's definitely not filled with super villains.
