The substance that comes out of a jet is primarily called jet exhaust, which consists of gases and water vapor produced during combustion in the engines. This exhaust can also contain small amounts of unburned fuel, carbon dioxide, nitrogen oxides, and other pollutants, depending on the engine's efficiency and operating conditions. When the hot exhaust gases mix with the cooler surrounding air, it can create visible water vapor trails, commonly known as contrails.
