An unprecedented cryovolcanism
A team of planetary scientists recently published an article in: where they explain that the images and data provided by strongly suggest that a region southwest of the Sputnik Plain does contain cryovolcanoes, but manifests in a way never seen before when considering other known cryovolcanoes in the solar system. †
This region had already caught the attention of researchers in 2015 because it seemed very different from the others and since then the analyzes of the images and the topography it revealed have continued. According to planetary scientists, other geological processes have shown that cryovolcanoes to create the observed features are unlikely. For example, the area has significant differences between the elevations of the terrain’s fortunes that could not have been created by erosion.
Data on the chemical composition of the intriguing structures that have been detected suggest that it is mainly water ice. But given Pluto’s average temperature, about 40(-233°C), even taking into account a small additional component with ammonia or methanol, the supposed cryovolcanoes should not emit liquid water and the visible flows should rather be comparable to those of the although it is indeed a matter of movements of analogous to that of liquid lava spewed out by volcanoes.
This is enough to revive speculation about the exact energy sources that make Pluto a still-living celestial body.
† One of the benefits of exploring new places in the solar system is that we find things we didn’t expect. These gigantic, eerie cryovolcanoes observed by New Horizons are a prime example of how we are expanding our knowledge of volcanic processes and geological activity on icy worlds. † stated Kelsi Singer, assistant scientist on the project new horizons from Southwest Research InstituteBoulder, Colorado, and senior author of the published article.
