Above the skies in Huntsville.I was on my way to work, coming off 565 West via exit 13 for Madison Blvd. I happened to look in the sky and saw a bright, white or silver disc-shaped object in front of some clouds.From my perspective, the object was heading towards my right. My first thought was that it was simply an airplane, although it appeared to be moving a bit fast for an airplane. However, its smooth appearance, lack of visible wings or propellers of any kind, and sheer brightness, made me think twice about that. Having seen and watched many helicopters, I knew it wasn't a helicopter from its shape and the way it was moving through the sky.The object disappeared from my view, being blocked by some trees, and I didn't think anything of it, until I saw it heading from behind the trees going towards my left (again from my perspective) At that point I had to make a turn, which led to the object being behind me and I lost sight of it.
