As was said by Q (TNG: Q Who?), the galaxy is wondrous, with treasures to satiate desires both subtle and gross. From the discovery of space lifeforms in the very first episode of TNG to a brilliant scientist igniting a star that had burned out, to the beauty of stellar phenomena, the galaxy is full of wonder.
No less wondrous, and part of Trek, is the exploration of human potential, and the things that can be achieved when people of disparate ethics and believes work together. In many ways, from Kirk and Spock working out how to act, and encountering the strange on the frontier of the history of Trek, to Deep Space Nine, where the crew focused on defending the ideals of the Federation, to where Burnham fought to preserve the integrity of the Federation in a time of near-certain defeat, to crews discovering new scientific mysteries across the franchise, and exploring new ways to think of life as we know it, Jim.
Trek is both the exploration of the galaxy, and the exploration of potential and evolution, and across its 54 years, 9 series, 13 episodes, and 780 episodes have shown us many wonders and challenges.
What do you think the most wondrous part of the Trek franchise is?
