Will Greta Thunberg win the Nobel Peace Prize?
Barack Obama, Malala Yousafzai and Nelson Mandela are just some of the people who've been given one of the most famous prizes in the world - the Nobel Peace Prize.
It's a pretty nice thing to get because it's saying you've done amazing work to help bring good into the world.
It's not the only Nobel prize - there are others including Literature, Chemistry and Physics. Among the winners are famous scientists like Albert Einstein and Marie Curie.
The prize is named after Sweden's Alfred Nobel who's most famous for inventing dynamite - a bit strange when his most famous prize is for peace!
It's been given out since 1901 and this week we'll find out who's won for 2019. Climate campaigner Greta Thunberg is thought to have a good chance to get it!
