The galaxy is mourning "Star Wars" actress and successful author Carrie Fisher, who died on Tuesday after suffering a heart attack. Among the countless heartfelt tributes from fans and Hollywood luminaries alike that have been pouring in since the news broke are several touching remembrances from Fisher's "Star Wars" costars and extended Lucasfilm family.

Mark Hamill, who plays Luke Skywalker in the series -- and brother of Fisher's Princess Leia -- tweeted out a short, stunned response to Fisher's passing, sharing a photo of the stars together and writing that he was "devastated" and had "no words."

Harrison Ford, who played Fisher's onscreen love interest Han Solo (and with whom Fisher recently revealed she had an affair while filming the original trilogy) released a statement praising the actress, and offering his support to her family and friends. His statement said:

"Carrie was one-of-a-kind...brilliant, original. Funny and emotionally fearless. She lived her life, bravely...My thoughts are with her daughter Billie, her Mother Debbie, her brother Todd, and her many friends. We will all miss her."

Many more costars paid tribute to Fisher on social media, including Billy Dee Williams (Lando Calrissian), Peter Mayhew (Chewbacca), Anthony Daniels (C-3PO), David Prowse (the original Darth Vader), and Warwick Davis (Wicket the Ewok from "Return of the Jedi").

More recent costars from "The Force Awakens" and the upcoming "Episode VIII" -- Lupita Nyong'o (Maz Kanata), Gwendoline Christie (Captain Phasma), and Andy Serkis (Supreme Leader Snoke) -- also offered their condolences, as did "Force Awakens" director J.J. Abrams and upcoming "Episode IX" director Colin Trevorrow.

Sweet Carrie.

"Star Wars" creator George Lucas released a statement praising Fisher's acting and writing talents, and "very colorful personality." Her Leia was "a great and powerful princess -- feisty, wise, and full of hope," he said.

Lucasfilm president Kathleen Kennedy also released a statement:

"Carrie holds such a special place in the hearts of everyone at Lucasfilm it is difficult to think of a world without her. She was Princess Leia to the world but a very special friend to all of us. She had an indomitable spirit, incredible wit, and a loving heart. Carrie also defined the female hero of our age over a generation ago. Her groundbreaking role as Princess Leia served as an inspiration of power and confidence for young girls everywhere. We will miss her dearly."

Disney CEO Bob Iger remembered Fisher in his own statement:

Fisher suffered a heart attack while on a flight from London to Los Angeles on December 23. She was rushed to a local hospital, where she remained until her death on Tuesday morning. She was 60.
