It's 100 years since Captain Scott and his team of British explorers arrived at the South Pole.
They were among the first people to try to cross the vast wasteland of Antarctica back in 1912.
Unfortunately Scott reached the pole five weeks after another explorer - Norwegian Roald Amundsen.
Sadly, Scott and his men never returned home but he discovered things that changed the way we understand the world forever.
Along the way Scott recorded new species and collected important rocks and fossils which helped scientists have a better understanding of the area.
He was one of the first people to experience such extreme conditions and his team had to deal with temperatures as cold as -30 degrees.
They didn't have very good equipment and it was hard for them to keep warm which made the expedition very difficult.
On their return from the Pole, bad weather delayed them and they failed to reach a vital supply store and none of the explorers survived.
It may have been 100 years ago that Captain Scott and his four companions reached the South Pole but they're still seen as British heroes to this day.
