150ft+ maybe bigger Transparent single ufo with lights disappears above heads, below and behind plane

Above Venus a transparent, elongated object started moving vertically with 1 bright, solid light at the top. It appeared to be moving away from us at first, pretty similar to a rocketships trail. I pointed asking my spouse what that was when we were on the porch, and we both couldn't take our eyes off it because it seemed different. We continued to watch and it started to come across the sky slowly. It appeared as one object, but almost transparent but could still make out a shape, the best thing to call it would be a saucer, the size was unreal I'm guessing 150ft long maybe more. It finally started hovering above our yard, and we both agreed there was distanct 7 lights in a line with even spaces. This was clearly from one object and it was lower than the plane that was passing near it to the right of it infront. The odd part of it was as my spouse reached for his phone to finally take a video as it was right above us. I was keeping my eyes on it and all the lights slowly dimmed and disappeared before he even looked back up. We both have seen questionable things in the sky before, as we are outdoor folk and have been in remote locations with open sky's but nothing has compared to this experience. We both questioned each other after, "Did we really just see that?" After that I felt eerie or as if being watched from a distance and was hearing some odd sounds that I couldn't explain, so we went inside. Its something you hear about but to see yourself was an experience.
