Saturn’s Enceladus could have the types of geologic features that prompted life on our planet. An investigation distributed this week in the diary Nature suggests that data from Cassini (a space probe studying Saturn and its natural satellites ) gives proof of potential hydro-thermal activity on the cold moon. Numerous planets and moons show proof of old springs and geysers, yet this is the first time researchers have discovered hints of continuous action.
The signs are in little grains of stones found close Saturn more than 10 years ago. Lately, researchers have discovered that the tiny grains are generally comprised of silica, which is available on sand found on our planet. They were extraordinarily uniform in size, proposing that some special process must have shaped them.
As per an exploration group lead via Sean Hsu, an research partner at the University of Colorado at Boulder’s Laboratory for Atmospheric and Space Physics, hydro-thermal vents in Enceladus’ sea are the most probable cause.
Frank Postberg, a Cassini CDA group researcher at Heidelberg University in Germany and study co-writer noted:
“We methodically searched for alternate explanations for the nano-silica grains, but every new result pointed to a single, most likely origin.”
Hsu further explained that the researchers believe that because of the gravitational analysis of the moon there is fluid water streaming between the frozen surface of Enceladus and the rock underneath. Yet for such consistent particles of silica to structure, there must be high temp water – about 200 degrees Fahrenheit – swirling up from deep inside the moon and hitting the cool of the surface.
Hsu was quoted by the Washington Post saying:
“Basically, we think that hot water interacting with rocks leeches out silica. And as the temperature drops, nanoparticles start to form. Depending on the condition of the silica solution, the particles will form at very particular sizes, like the ones we’ve detected.”
In the event that Saturn’s satellite is experiencing these dynamics, then it could have the required fixings to develop life. That doesn’t imply this is really happening according to the formula.
Hsu clarified that in the absence of sunlight something like hydro-thermal activity is necessary to give energy to life. This hydro-thermal activity would give energy and heat siphon minerals out from rock, and obviously involve fluid water.
Regardless of the possibility that the vents are there, Hsu said, scientists don’t know to what for how long they’ve been there and in order for life to develop it needs a stable environment.
