Ocean planets as a research area concerns the theoretical prediction, characterization, and observational identification of exoplanets with deep, global water layers potentially hundreds of kilometers thick, lacking significant exposed landmasses. This field integrates planetary formation models, high-pressure water and ice phase diagrams, interior structure and heat transport modeling, and atmospheric-ocean coupling to assess habitability and observable signatures. Research focuses on how volatile delivery, disk chemistry, and migration produce water-rich worlds, how high-pressure ice mantles affect geochemical cycling and climate regulation, and how spectroscopic biomarkers and bulk density constraints can distinguish ocean planets from terrestrial, mini-Neptune, or sub-Neptune exoplanets in current and future surveys.
According to astronomers, water worlds, though admittedly not those containing Kevin Costner, are one of the most common types of planets in our solar system. This is partly due to low density estimates and the abundance ...

At first glance, Saturn's moon Enceladus seems rather unremarkable: it is much smaller than the Earth's moon and is far away and completely covered in ice.

For astrobiologists, the search for life beyond our solar system could be likened to where one would look in a vast desert—essentially, where there's water. And it turns out that one of the most common types of exoplanet ...

People have long wondered what life was first like on Earth, and if there is life in our solar system beyond our planet. Scientists have reason to believe that some of the moons in our solar system—like Jupiter's Europa and ...

On Earth, water is so intertwined with life that our search for life on other worlds is essentially a search for water. When scientists find exoplanets around distant stars, a primary consideration is if they're in the stars' ...

Hycean worlds are also called ocean worlds. They're planets covered in oceans that also have thick hydrogen atmospheres. There are no confirmed hycean worlds but many candidates. Even though they're only candidates so far, ...

Scientists are revolutionizing the search for extraterrestrial life by challenging our somewhat Earth-centric assumptions about where and how life might exist in the universe. A new review argues that we must embrace the ...
