It has been 50 years since the first episode of Star Trek was broadcast, bringing Mr Spock, Captain Kirk and Lieutenant Nyota Uhura to our TV screens.
Naturally, Trekkies are excited.
Fans paid tribute to the timeless TV show on its birthday.

One fan yearned for her own moment of tenderness like Captain Kirk and Mr Spock.
I just want someone to look at me the way Captain Kirk looked at Mr. Spock.#StarTrek50 pic.twitter.com/pmiYmTYWcU

People paid tribute to the show, which featured a diverse cast and the first inter-racial kiss between a white man (Kirk) and a black woman (Uhura, as played by Nichelle Nichols) on television.

The best and most inspiring dream of Star Trek is the all inclusive multi-racial multi-species crew

showed us that sometimes the best thing you can do for the worst parts of society is to let them self-destruct. History always marches on.
