The photo is a Twitter thread. A user (@egzodus) posted about a historical rivalry ending, possibly between Adana and another region, and sending a representative to a certain location (presumably the sun, in a metaphorical sense). Another user (@iyikiogrendim) responded with news about Deniz Burnham, an Adana-born candidate for NASA astronaut training. The joke, in Turkish, plays on the juxtaposition of a seemingly historical or political statement ("1000 yıllık düşmanlık son buluyor. Adana, Güneşe temsilci gönderiyor") with the much more contemporary and positive announcement of a local person achieving a significant goal. It highlights the absurdity and humorous contrast between these two different kinds of "sending a representative." It's a lighthearted commentary on the unexpected and possibly exaggerated nature of the first post. The implied humor is that a historical, potentially tense, event is now overshadowed by the achievement of a local.
