In a recent breakthrough, NASA has discovered 17 exoplanets that may harbor oceans of liquid water beneath icy shells. Although these distant planets lie outside the habitable zone of their host star, they defy expectations by maintaining the potential for liquid water through internal heating. This exciting finding has increased prospects of finding signs of life on these icy exoplanets.
Interestingly, this phenomenon is not exclusive to these newly discovered exoplanets. Moons such as Europa of Jupiter and Enceladus of Saturn also possess liquid oceans beneath their icy surfaces despite limited sunlight exposure. The similarities between these moons and the newfound exoplanets have piqued the curiosity of scientists, who believe these icy worlds could serve as promising targets for scientific exploration.
NASA’s research team has even estimated the amount of geyser activity that could potentially occur on these exoplanets. Geyser activity involves water erupting through the icy crust, creating visible plumes. Of particular interest are two exoplanets, Proxima Centauri b and LHS1140 b, which are located close enough for telescopes to potentially observe these eruptions. This unprecedented opportunity may bring us closer to understanding the dynamics of these distant worlds.
While these exoplanets are roughly Earth-sized, they differ significantly from our planet in terms of density and surface conditions. The lower density and extreme cold on these exoplanets suggest that their surfaces are predominantly covered in ice. Nonetheless, the anticipated geyser activity on Proxima Centauri b and LHS1140 b could potentially surpass that of Europa by hundreds to thousands of times.
Scientists believe that telescopes are most likely to detect geological activity on these two promising exoplanets due to the predicted proximity of the oceans to their surfaces. By observing the eruptions and studying their characteristics, researchers hope to gain insights into the composition and potential habitability of these icy worlds.
In conclusion, the recent NASA study identifying 17 exoplanets with potential liquid water beneath icy shells has sparked excitement within the scientific community. Despite their remote locations and frigid environments, these exoplanets hold the promise of revealing signs of life. With Proxima Centauri b and LHS1140 b in close range of telescopes, the quest for understanding these mysterious, icy worlds reaches an unprecedented milestone, offering astronomers a chance to observe geological activities in distant corners of the universe.
