Create a futuristic detailed but symmetrical city-size deep-space spaceship, the SF-6410 ATHENA, with two distinct sections joined by a thick, reinforced connector. The front section is sleek and larger, tapering towards the front with angular windows. No windows on top. The rear section is a rounded rectangular shape, housing four large glowing blue nacelles, two on each side. The two sections are connected by a thick, cylindrical structure that is heavily armored and features visible conduits running along its length.

The background is a starry expanse with a faint nebula, highlighting the ship's presence in deep space --s 888  --ar 19:13
