VERY big sun

I logged into Minecraft 1.9, and was happy to see it was released. I went into my hard-worked 1.8 world to have a fun time, and I'm instead created with a giant, distracting sun. There's no way it's not a bug, so I had to report it. I hope it can be fixed, cause I had a lot on my 1.8 world I intended to keep.

I expected the sun to be normal sized...

The sun was was instead gigantic.

Steps to Reproduce:
1. Use the minecraft 1.9 version and log into a 1.8 world

That should be all. It's a little creepy, not gonna lie.

Note the moon is the normal sized, it's just the sun that's huge.
