CBS will celebrate 'Star Trek' Day 2020 with an epic Trek panel marathon. Here's what to know.

It's been an incredible 54 years since "Star Trek" first debuted. On Tuesday (Sept. 8), actors from across the multi-decade franchise will celebrate an online "Star Trek" day with panels and discussions, while discussing the series' emphasis on diversity.

More than three hours of free virtual panels will play at the Star Trek Day website here starting at 12 p.m. PDT (3 p.m. EDT or 1900 GMT).

The multi-hour online event comes in the wake of a CBS announcement Sept. 2 that "Star Trek" will feature its first nonbinary and transgender characters in Season 3 of "Star Trek: Discovery," which premieres Oct. 15. Adira will be a nonbinary character played by non-binary actor Blu del Barrio, while transgender actor Ian Alexander will play Gray.
