Alien oceans are home to some unusual chemistry

Exoplanets rich with water appear to be common around other stars. A new study examines conditions at the bottom of these massive seas in other worlds. Alien oceans may be common throughout the Universe, but little is known about conditions deep underwater on massive worlds orbiting alien stars. A new study recreated these extreme conditions, with surprising results. Neptune, at the edge of our own Solar System, is a perfect example of a massive, water-rich world. Astronomers believe such planets, where layers of water hundreds or thousands of miles deep surround rocky cores, are common around other stars. Water worlds…
