"Lava planets are in such extreme orbital configurations that our knowledge of rocky planets in the solar system does not directly apply." ...

Astro Brief is a collaboration between KSMU, the Missouri Space Grant, and MSU's Department of Physics, Astronomy and ...

Scientists have developed a new and improved method to better understand "steam world" exoplanets, a move that could refocus ...

Among the most extreme planets discovered beyond the edges of our solar system are lava planets: fiery hot worlds that circle so close to their host star that some regions are likely oceans of ...

The reliable detection of a large ocean on an exoplanet would be an exciting discovery. It would open the door to a new understanding of exoplanets, their potential habitability, and even how ...

An ultra-short period planet is spiraling toward destruction within 31 million years. Its extreme heat and dense composition reveal a violent past. Our circumstances here on the wondrous, ...

More water worlds than we thought might support life Too much water on exoplanet surfaces would mean high pressure ices, not life.

Astronomers have detected the most promising signs yet of a possible biosignature outside the solar system. The most likely reason (when combined with other observation) for seeing 1000 times more of ...

NASA's James Webb Space Telescope discovered a super-Earth exoplanet that may have an ocean of water approximately the size of the Atlantic.

The James Webb Space Telescope (JWST) has captured its first direct image of a previously unknown exoplanet — a planet that orbits outside the solar system.

Scientists have proposed that sub-Neptune exoplanets orbiting in the habitable zone, where liquid water can exist on the surfaces of planets, could be massive ocean worlds with thin hydrogen-rich ...

While lava worlds represent an exciting new frontier in exoplanet science, much remains unknown about their dynamics, interiors and evolutionary paths.
