[Mass Effect] Why are slugs fired by ships glowing?

Ships in ME fire metal slugs propelled by mass effect fields, sort of like a railgun. So why do the ones in space glow? I understand when firing the guns in atmosphere they rounds move so fast they turn the air around them to plasma so them glowing makes sense, but why in space are the slugs glowing bright blue?

The shells are glowing because they are hot, A result of very strong and unevenly applied gravity field during launch. The same tidal differences that would spagetify a human are at work on the slug, because gravity is orders of magnitude stronger at the tip of the slug (where the attractor field is generated) than at the base. The heat is generated by the friction of the slugs molecules resisting the spaghettification and remaining in shape.
