Out actors Zachary Quinto and George Takei are among the countless paying tribute to the late actor Leonard Nimoy, who passed away Friday at his home in Los Angeles. He was 83.

Quinto, who took over Nimoy's role of Spock in the Star Trek reboot, tweeted: “I love you profoundly my dear friend, and I will miss you every day. May flights of angels sing thee to thy rest.”

Quinto worked with Nimoy on two films.

Takei, who played Lieutenant Sulu in the original Star Trek, said of Nimoy's passing: “Today, the world lost a great man, and I lost a great friend.”

He continued: “We return you now to the stars, Leonard. You taught us to 'Live Long And Prosper' and you indeed did, friend. I shall miss you in so many, many ways.”

Nimoy succumbed to chronic obstructive pulmonary disease.
