Star Trek actress Nichelle Nichols, who played Lieutenant Nyota Uhura, has died aged 89.
Nichelle's son Kyle Johnson announced the news on Instagram today.
He said: "Friends, Fans, Colleagues, World.
"I regret to inform you that a great light in the firmament no longer shines for us as it has for so many years.
"Last night, my mother, Nichelle Nichols, succumbed to natural causes and passed away. Her light however, like the ancient galaxies now being seen for the first time, will remain for us and future generations to enjoy, learn from, and draw inspiration."
Nichelle made history when she shared the first interracial kiss ever aired on TV, with white actor William Shatner.
The ground breaking actress played the ship's communication officer in the space opera series, which first aired in 1966, and concluded in 1969, it's impact lasting for decades.
Hers was one of the first large roles for a black woman in a US TV show, and she broke stereotypes that had limited black female actors.
She often recalled how the Rev Martin Luther King Jr was a fan of the show and praised her role and personally encouraged her to stay with the series.
Like other original cast members, Nichols also appeared in six big-screen spinoffs, starting in 1979 with Star Trek: The Motion Picture and at Star Trek fan conventions.
Her son's statement continued: "Hers was a life well lived and as such a model for us all.
"I, and the rest of our family, would appreciate your patience and forbearance as we grieve her loss until we can recover sufficiently to speak further."
Concluding his post, and referencing a famous Star Trek quote, Kyle said: "Live Long and Prosper."
Nichelle served for many years as a Nasa recruiter, helping bring minorities and women into the astronaut corps.
More recently, she had a recurring role on television’s Heroes, playing the great-aunt of a young boy with mystical powers.
Tributes to the pioneer have poured in.
