Actress Mira Furlan, who played Minbari Ambassador Delenn on the sci-fi drama series Babylon 5, passed away Jan. 20. She was 65.

Furlan’s death was announced by Furlan’s Twitter account and confirmed by Babylon 5 creator J. Michael Straczynski, who paid tribute to the accomplished actress.

Upon her arrival in the U.S., Furlan quickly landed the role of Ambassador Delenn in Babylon 5, which ran for five seasons.

Following the end of the Yugoslav Wars in 2001, Furlan started traveling back and forth between Hollywood and Croatia, acting in film and TV projects in both countries. In the U.S., she played Danielle Rousseau on ABC’s Lost.
