"Star Trek" actress Nichelle Nichols died on Sunday, according to a post shared by her son Kyle on her official Facebook page. She was 89.

"I regret to inform you that a great light in the firmament no longer shines for us as it has for so many years," he wrote. 

"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."

Nichols was known for playing Lieutenant Nyota Uhura on all three seasons of the original show, which ran from 1966-1969. She also starred in each of the six "Star Trek" films from 1979 through 1991.

Sending my love and condolences to her family."

"We lived long and prospered together," Takei wrote. "I shall have more to say about the trailblazing, incomparable Nichelle Nichols, who shared the bridge with us as Lt. Uhura of the USS Enterprise, and who passed today at age 89. For today, my heart is heavy, my eyes shining like the stars you now rest among, my dearest friend."

She earned accolades for breaking stereotypes for black actresses, with the Rev. Martin Luther King Jr. personally encouraging her to stay with the TV series when she expressed doubts about continuing working on the program. 

She met him at a civil rights gathering in 1967, at a point when she had decided not to return for the show's second season.

He said, 'You cannot do that,'" Nichols recalled. "You've changed the face of television forever, and therefore, you've changed the minds of people," she said the civil rights leader told her during a meeting.

During the third season of "Star Trek," Nichols and Shatner made television history when they shared an interracial kiss.
