Fireworks display
From Memory Alpha, the free Star Trek reference
A fireworks display is a celebratory event comprised of explosions of light and sound given off by a firework or other light source.
In 2371, Benjamin Sisko successfully navigated a replica of an eight hundred-year-old Bajoran spaceship from Deep Space 9 to Cardassia, giving evidence to the theory that ancient Bajorans had done the same. Upon reaching Cardassia, he was greeted with fireworks. (DS9: "Explorers")
In early 2373, Enrique Muniz, who was in delirium shortly before his death, mistook the Dominion's ultritium concussion shell bombardment of the ship he and others were trapped in on Torga IV, as a fireworks display like those of the carnival he had attended before. (DS9: "The Ship")
In an alternate timeline, in which the USS Voyager did not return to Earth until 2394, the ship was greeted in San Francisco with fireworks. (VOY: "Endgame")
In another alternate timeline, the Delta Flyer reached Earth by using a quantum slipstream drive. When they reached Earth they were received with antimatter fireworks. (VOY: "Timeless")
