What is the first criterion to defining a habitable environment for humans? Water to sustain life. Through NASA’s Hubble Space Telescope, scientists were able to observe water vapor above the south polar region of Europa, providing the first solid evidence of the existence of an ocean under Europa’s icy crust.

Researchers are able to speculate that the water vapor is most likely generated when water plumes erupted on the surface. If these findings are proven to be true, this would make Europa the second moon in the solar system known to have water vapor plumes. Also, the evidence provides a general idea of the chemical makeup of Europa and its potential of becoming a habitable environment, without digging through the layers of ice.

Since this moon has a strong gravitational pull, majority of the -40°F vapor would fall back onto the surface, rather than escaping into space. This new observation, if confirmed, can demonstrate the reliability and power of the Hubble Space Telescope, and its ability to explore new worlds for potentially habitable environments in our solar system.
