Revealing the secret of the ocean outside Earth, suspecting new life

New data from NASA shows that moons in the Solar System have giant oceans hidden under thick layers of ice.

Oceans are not only found on Earth. Many celestial bodies in the Solar System such as Europa, Enceladus or Titan are believed to possess giant underground oceans under their ice layers. Photo: Pinterest.

Europa – a moon of Jupiter – may have more water than Earth. Beneath Europa’s ice crust tens of kilometers thick is an ocean hundreds of kilometers deep, where microbial life may exist. Photo: Pinterest.

Enceladus spews water into space. This moon of Saturn was photographed by the Cassini spacecraft as plumes of water vapor and ice particles spewed from its subterranean ocean through fissures at its south pole. Photo: Pinterest.

Titan, another moon of Saturn, has seas and lakes made of methane. Unlike water, liquid methane exists at extremely low temperatures, creating a “rain-river-lake” cycle similar to Earth but with a completely different chemistry. Photo: Pinterest.

Ganymede is the largest moon that could contain multiple ocean layers. Models show that the Jupiter satellite has alternating layers of liquid water and ice, making it a “multi-ocean” world . Photo: Pinterest.

Pluto may also have an underground ocean. Data from New Horizons suggests that beneath the dwarf planet's icy nitrogen layer lies a layer of liquid water that hasn't completely frozen. Photo: Pinterest.

These oceans could sustain life. Heat from the planet's core or tidal interactions with the parent planet would keep the water from freezing completely, creating conditions for life to develop. Photo: Pinterest.

Exploration plans are underway. NASA missions like Europa Clipper and Dragonfly will soon explore “extraterrestrial oceans,” opening a new chapter in the search for life in the universe. Photo: Pinterest.
