premise: A team of European and American astronomers say that a recently discovered extrasolar planet, located not far from Earth, contains oceans and rivers of hot solid water. The team discovered the planet, Gliese 436 b, which is roughly the size of Neptune, using the Geneva Observatory and it is roughly 33 light-years away from Earth. "The water is frozen by the pressure but it's hot. It's a bit strange — we are used to water changing conditions because of temperature, but in fact water can also be solidified by pressure. It's not a very welcoming planet," said one of the astronomers who discovered the planet, Frederic Pont.
hypothesis: Gliese 436 b was found by scientists from America and Europe.
