The following is a brief look at the chronological events that have taken place in the Star Trek Universe. These entries (up to the beginning of the second season of DS9) are taken from work derived by Michael and Denise Okuda, and can be found in greater detail in the book Star Trek Chronology: The History of The Future. These lines can also be found in The Star Trek Encyclopedia. From the second season of DS9 onwards I've tried to highlight Trek events as faithfully as possible. Although I have an updated chronology going to the very end of the seventh season of DS9, I've kept my original entries (in Blue) that I added to the old list that only went up to 2370. In a few cases, I've added a few amendments and updates from established information, which had either not 'occurred' at the time the original list was published, or was omitted for whatever reason. This page will be updated as and when…

Entries in the list are separated and governed by the year in which they occurred. My own inserts are in Blue 

Star Trek Universe Time Line
1609: Galileo Galilei builds the first astronomical telescope. His observations about the moon, planets in the solar system, the sun, and individual stars in the Milky Way confirm Copernican theories. The sky is no longer the sole domain of mystics.
1799: Astronomer Giovanni Schaiparelli observes what he believes are markings on Mars, which he calls canali – Italian for channels or furrows. Canali is misinterpreted as "canals," suggesting artificial structures. With subsequent writings by Percival Lowell and others, humans actively speculate about intelligent life on other worlds.
1873: Crew of Enterprise-D travel back to nineteenth century to thwart incursion by Devidians. There they meet Mark Twain. Picard first meets Guinan.
1903: The Wright Brothers build and fly the first motorized airplane in Kitty Hawk, North Carolina, forever giving mankind "wings."
1905: Albert Einstein introduces his Special Theory of Relativity and contributes to the development of quantum theory. Introducing the concept of space-time and postulating that mass and energy are equivalent and transposable, he formulates the equation E=mc². In doing so, Einstein predicts that the velocity of light is the absolute "speed limit" in the universe.
1927: Aviator Charles Lindbergh makes the first nonstop solo transatlantic airplane flight and galvanizes world interest in aviation.
1936: American warship USS Enterprise CV-6, a Yorktown-class carrier, launches. After barely missing the Japanese attack on Pearl Harbor in 1941, the Enterprise will participate in every major battle in the Pacific theater during World War II and become one of the most decorated ships in U.S. history.
1937: Aviator Amelia Earhart, who captured the world's attention as the first woman to match Lindbergh's transatlantic flight, vanishes somewhere over the Pacific Ocean while attempting to circumnavigate the globe.

- Although unverified, its been reported that in October of this year a Vulcan scientific party observes Earth and the Sputnik launch. After three weeks of surreptitious intelligence gathering, the party is forced to land on the planet. The fate of the four Vulcans remains a mystery.

1960: Radio astronomer Frank D. Drake carries out humanity's first attempt to detect interstellar radio transmissions in an effort called SETI (Search for Extraterrestrial Intelligence). The stars chosen by Drake for the first SETI search are Tau Ceti and Epsilon Eridani.
