Scientists looking at data pulled from NASA's Cassini spacecraft may have found out how Saturn's ocean moon Enceladus remains geologically active.

The research, published in Nature Astronomy, suggests that tidal currents flow through the moon's porous core where rocks rub together and generate heat that warms the ocean. According to the European Space Agency, this tidal heating is primarily caused by the gravitational pull of Saturn.

Writing in 2008, the space agency speculated that the deep sea vent theory could apply to life on Enceladus. When applied to Earth, this suggests life originated from chemical, heat and tidal interactions beneath the seabed.

NASA previously said Encedalus has all the ingredients for life, reported CNET, citing the space agency.
