In a groundbreaking study, USA’s National Aeronautics and Space Administration (NASA) scientists have unearthed a treasure trove of 17 exoplanets beyond our solar system that could potentially host oceans of liquid water beneath their icy exteriors.
The 17 confirmed exoplanets share Earth’s size but differ in density, suggesting a composition rich in ice and water rather than dense rock.
What sets these distant worlds apart is the possibility of occasional eruptions, akin to geysers, venting through their icy crusts.
The research delved into the depths of these exoplanets, revealing the prospect of subsurface oceans.
Among them, two exoplanets orbit close enough to Earth, presenting an exciting opportunity for astronomers to witness these icy eruptions firsthand through powerful telescopes.
While the exact makeup of these distant worlds remains shrouded in mystery, initial estimates propose surface temperatures much colder than Earth, hinting at a frosty-exterior-concealing hidden oceans.
The revelation has sparked intrigue as scientists ponder the potential existence of life within these subsurface oceans.
The key lies in the existence of essential elements, a viable energy supply, and compounds crucial for biological processes.
Drawing parallels to Earth’s enigmatic ocean depths, where thriving ecosystems exist in complete darkness around hydrothermal vents, the researchers are optimistic about the possibility of life beyond our home planet.
The study took a leap forward by refining surface temperature estimates for each exoplanet.
Leveraging the known properties of Europa, Jupiter’s moon, and Enceladus, Saturn’s moon, researchers recalculated surface temperatures using surface brightness data.
Additionally, the shape of each exoplanet’s orbit became a crucial factor in estimating internal heating, providing a more comprehensive understanding of these distant icy realms.
As the scientific community eagerly awaits further exploration, these findings mark a significant stride in our quest to unravel the mysteries of the cosmos.
