Answer:
I am the second L in LOL.
I am seen in the water. If seen in the sky I am in the rainbow a jay's feather and lapis lazuli.
I have thirteen hearts but no body or soul.
I soar without wings I see without eyes. I've traveled the universe to and fro. I've conquered the world yet I've never been anywhere but home.
I start new then become old. Start clean but be one dirty. I usually start big then become little.
It's what light turns into in the night
