More recently, scientists reviewed data over the past decade and came to the conclusion that the two satellites of Jupiter and Saturn can have an environment suitable to sustain life. During a flight over Saturn’s moon Enceladus in October 2015, the Cassini spacecraft was struck by a gas release, which is likely to have been hydrothermal geyser, which pierced the icy surface of the satellite. The researchers suggest that such emissions are evidence of a sufficient amount of chemical energy for the development of primitive organisms. Also through research of similar geysers on Europa (Jupiter’s moon), NASA announced that the two celestial bodies can support life.

More recently, scientists reviewed data over the past decade and came to the conclusion that the two satellites of Jupiter and Saturn can have an environment suitable to sustain life. During a flight over Saturn’s moon Enceladus in October 2015, the Cassini spacecraft was struck by a gas release, which is likely to have been hydrothermal geyser, which pierced the icy surface of the satellite. The researchers suggest that such emissions are evidence of a sufficient amount of chemical energy for the development of primitive organisms. Also through research of similar geysers on Europa (Jupiter’s moon), NASA announced that the two celestial bodies can support life.

How was it discovered?

In the release through which Cassini flew by, had traces of hydrogen. Scientists believe that the gas produced by the chemical reaction that takes place in geothermal sources at the bottom of the oceans of Enceladus. There are similar sources in the same places, where hydrogen is combined with carbon dioxide produces methane in a process known as “methanogenesis”. Theoretically it is considered to be a key component for microbial life on our planet.

More precisely, scientists have found microbes on Enceladus, but they are confident in the processes that produce the chemical energy necessary for life. Even if researchers will find any germs, they will not be similar to the earth, because they appeared in a completely different chemical environment. But any evidence of life, even bacteria, will be an incredible discovery. Also, like the geysers (although much less) erupt on Europa, which has an icy surface like Enceladus. Potentially, this provides the same conditions for life.

Employees of the Space center’s Goddard compared ultraviolet images of Europe taken by the Hubble space telescope in 2014 (then was first discovered the gas emissions from the satellite) with those taken in 2016 and again found the geysers. Although 12 images, which filmed the area of location of the emission, traces of hydrogen geysers are only two, that’s enough to continue the search. The potential similarity of hydrothermal processes on Europa to Enceladus is confirmed by infrared images taken by the Galileo probe, where the thermal activity was observed directly under the location of the gas emission.

What’s next?

September 15 SAP probe will plunge into the atmosphere of Saturn and burn up in it, so the spacecraft will not be able to make a new photo of Enceladus. But the new space station Europa Clipper, which will be launched in the next decade, will carry out a flight over Europe on the way to its main goal – to Jupiter. New infrared photos from this probe will help you take a closer look at the same place that Galileo was filmed 15 years ago. While Europa Clipper will be additional equipment, such as ultraviolet sensors to collect additional data. Now that scientists know where and what to look for, NASA will send the latest spacecraft in one of the places in the Solar system where life might exist.
