From the International Space Station to the Vatican, tributes have poured in for rock legend David Bowie following his death at 69 from cancer.
Taking to social media as well as in statements, music world collaborators and fans praised Bowie's groundbreaking oeuvre and offered their own recollections of the singer, known for a string of hits such as "Space Oddity" and "Let's Dance".
Below are some of the tributes to Bowie, who released his last album "Blackstar" on Friday, also his birthday:

"He always did what he wanted to do. And he wanted to do it his way and he wanted to do it the best way. His death was no different from his life - a work of Art. He made 'Blackstar' for us, his parting gift. I knew for a year this was the way it would be. I wasn't, however, prepared for it. He was an extraordinary man, full of love and life. He will always be with us. For now, it is appropriate to cry."
