Water Vapor Detected For The First Time On The Largest Moon In The Solar System, Ganymede

Suara.com – Astronomers find evidence of water vapor in the atmosphere wrong Jupiter’s moon and the largest moon in the solar system, Ganymede, for the first time.

Ganymede has a surface covered with a layer of ice.

Experts believe Ganymede may have a liquid ocean 161 kilometers below its surface.

Such an ocean is likely to hold evidence of life.

By analyzing data from the Hubble Space Telescope collected over the past two decades, scientists at NASA eventually found evidence of water vapor in Ganymede’s thin atmosphere.

Reported from Science Alert, Wednesday (28/7/2021), this water vapor may not come from the subsurface ocean.

On the other hand, the ice may evaporate from the moon’s surface.

While there is no definitive evidence it harbors alien life, this water vapor has helped add to expert knowledge of Ganymede’s atmosphere.

Previously, researchers only knew that the moon’s atmosphere contained oxygen.

“So far only molecular oxygen has been observed in its atmosphere,” said Lorenz Roth of the KTH Royal Institute of Technology in Stockholm, Sweden.

Previous research has only revealed that oxygen is produced when particles erode the surface of the ice.
