In the article"The Possibility of Life on Europa and Enceladus" by Craig Levin, his theory was that billions of years ago, Jupiter and Saturn were very hot which was "the result of the respective planet's collapse into a dense ball of rock, metal, and liquid metal hydrogen." Could this have produced UV rays? This article was published in 1990, and I was wondering if this was actually possible or may have even happened.
