Calling all Trekkies!
Today marks the 50th Anniversary of Star Trek and Trekkies are celebrating the galactic milestone all around the world.
On September 8, 1966, exactly 50 years ago today, the very first episode of Star Trek aired.
People are using the hashtag #StarTrek50 on Twitter to share their best Trekkie selfie.
Even Facebook has gotten in on the celebration with custom like buttons.
There have been more than a dozen Star Trek series over the years, but in honor of the 50th anniversary, we're taking it back to the original series for all the OG Trekkies.
