Climate Model Flags 87-Light-Year Exoplanet as Liquid-Water Candidate
3 articles · Updated · iowaparkleader.com · May 21
3D simulations identified several climate states in which the exoplanet could keep surface temperatures within a liquid-water range, making it a plausible—though unconfirmed—candidate for habitability.
The model found those outcomes under different atmospheric setups, including hydrogen-rich air that redistributes heat and nitrogen-CO2 mixes whose clouds reflect enough starlight to prevent overheating.
Some promising runs produced an “eyeball” ocean—liquid water on the star-facing side and ice on the nightside—while efficient day-night heat transport kept freezing from spreading too far.
At 87 light-years, the planet is close enough for follow-up spectra and thermal phase curves that could test for water vapor, CO2, methane, atmospheric mass and stellar activity.
Researchers stressed the work does not detect life or oceans; uncertain clouds, aerosols, surface conditions and flare-driven atmospheric loss still leave the planet’s true habitability unresolved.
This alien world may have water, but does it have the active geology needed to sustain life for billions of years?
This nearby 'eyeball' world could have a liquid ocean, but how can we prove it's not just a barren, tidally-locked rock?
If we detect signs of life on this world, how can we be certain it is not just a chemical or geological false alarm?
HD 137010 b: Discovery and Habitability Prospects of a Nearby Earth-Sized Exoplanet Colder Than Mars
Overview
The recent discovery of HD 137010 b, announced in early 2026 and published in The Astrophysical Journal Letters, has captured the attention of astronomers due to its Earth-like size and intriguing characteristics. Although it shares similarities with Earth, HD 137010 b is much colder because it receives less than one-third of the sunlight our planet gets. This makes it a fascinating candidate for further study, especially in the search for habitable worlds. Its unique features highlight the importance of continued observation and advanced research to understand its true nature and potential for supporting life.
