Examples include Jupiter’s moon Europa and Saturn’s moon Enceladus. These worlds have become prime candidates in the search for extraterrestrial life.
Earth's Unique Oceans
Earth’s oceans cover over 70% of its surface and are home to diverse ecosystems. These vast bodies of water play a crucial role in our planet’s climate and are essential for supporting life.

For instance, the salty subsurface ocean of Europa is thought to be chemically similar to Earth’s oceans. This similarity raises intriguing questions about the potential for life on other planets.
The Role of Hydrothermal Vents
Hydrothermal vents on Earth’s ocean floor support unique ecosystems that thrive without sunlight. These vents are powered by the planet’s geothermal energy, creating a rich environment for life.
