Non blinking bright blue light slowly in sky over highway i57 illiniosmy friend and I were headed north on illinois 57, a highway at a speed of about sixty at ten at night when I was glancing threw the sky, I've been seeingstrange lights recently so I decided to keep looking while we traveled home from a friend. I noticed a brighter blue light light than any other star, showed my friend and said this looks weird like I've never seen something that bright here in chicago. While watching it while driving we saw that it was moving at us but that it was not blinking and was far but did pass over us, like I said we were traviling fast. I then took two photos and watched confused as it went into the distance. When it did finally pass we noticed two lights or engins, seems kind of yellow but blue and definitely blended together cuz of distance. It made progress threw the clear night sky but not that fast. Object traveled from north west and was going east at about ten pm.
