Sunset in Adelaide

Yesterday evening I left the Synagogue and beheld this magnificent sunset. It got me thinking, why is there no blessing on a beautiful sunset. We make a beracha on smelling a nice smell, like a rose. And this blessing could be made every day. So why not on a beautiful sunset every day?

We make blessings when seeing the ocean, the grand canyon and other magnificent creations of G-d.

Anyone have an answer?
