Leonard Nimoy has died at the age of 83, and Hollywood has taken to social media to mourn the “Star Trek” icon, from fellow “Trek” alums like William Shatner and George Takei to comedy stars including Seth MacFarlane and Jason Alexander.

The Hollywood Historic trust also announced that flowers will be placed on Nimoy’s star on the Hollywood Walk of Fame at 10:30 a.m. Friday. The star is located at 6651 Hollywood Blvd.

Rod Roddenberry, CEO of Roddenberry Entertainment and son of “Star Trek” creator Gene Roddenberry, released a statement on Nimoy’s passing: “The death of Leonard Nimoy is indeed an immense loss to us all. I only hope that during this difficult time we can all take comfort in the everlasting impact he has made. As Spock he portrayed the first Roddenberry character, an outsider who truly let us see ourselves. Leonard Nimoy’s talent allowed millions to learn more about who we are and who we want to be. I will always thank him for that.”

President Obama also paid tribute to Nimoy, writing: “I loved Spock. In 2007, I had the chance to meet Leonard in person. It was only logical to greet him with the Vulcan salute, the universal sign for “Live long and prosper.” And after 83 years on this planet – and on visits to many others – it’s clear Leonard Nimoy did just that. Michelle and I join his family, friends, and countless fans who miss him so dearly today.”
