Scientists Recreate Icy Moon Volcanoes in Lab, Unlocking Secrets of Cryovolcanism
A team of scientists has successfully simulated the volcanic processes on icy moons like jupiter’s Europa and Saturn’s Enceladus within a specialized low-pressure chamber nicknamed ‘George’. This facility, officially known as the Large Dirty mars Chamber at the Open University in England, allowed researchers to study a phenomenon called effusive cryovolcanism, which has been challenging to observe directly.
europa and Enceladus are of particular interest to scientists searching for extraterrestrial life due to the presence of vast subsurface oceans and observed geological activity. Enceladus, for instance, experiences explosive cryovolcanism, ejecting massive jets of water vapor into space at its frigid equatorial temperatures of -193 degrees Celsius. Scientists also hypothesize that effusive cryovolcanism, where liquid is released onto the surface like lava flows on Earth, occurs alongside these explosive events.The research team focused on understanding this less-understood effusive process. By introducing large volumes of water into the near-vacuum of the Large Dirty Mars chamber, they observed its behavior as the pressure decreased. Contrary to previous assumptions that a thick ice crust would form and seal off the water, the experiments revealed a dynamic process.As the pressure dropped, the water began to bubble and boil despite its low temperature. This boiling caused heat to dissipate, leading to the formation of a thin ice layer on the surface. However, the liquid water beneath continued to boil, creating bubbles that broke thru and deformed the ice. This allowed liquid water to escape through cracks onto the surface, mimicking effusive cryovolcanism.
These findings challenge earlier studies that used smaller water volumes and suggested a complete sealing of the water. The researchers believe their new understanding of this “boil-freeze-bubble-crack-repeat” cycle could be crucial in identifying ancient signs of cryovolcanic activity on icy moons and other celestial bodies. This,in turn,could help pinpoint specific locations in the ongoing search for evidence of ancient microbial life.
