I was just sanding outside having a smoke looking up at the sky and I saw something weird. It looked like the sky was being magnified

As the title says. The sky looked magnified it looked kinda like a v wing shape with a tail wing. That's the best way I can put it towards ya. The sky was magnified around the shape of it as it moved really realty fast north to south. I can't quite say what it was I'm just blown away how quiet it was. Other aircraft where flying around, but I couldn't, couldn't hear a damn thing from it.
The leading edge was curved and the stars or what ever pattern it was bent around the edge.
