Hubble Detects Water Vapor on Jupiter's Ganymede

Scientists and astronauts still observing near-Earth planets to detect any evidence of water on them. Therefore, the prestigious Hubble space telescope announced on Monday detecting water vapor on Jupiter's Ganymede moon.

The official website of the telescope's staff explained that it captured vapor which is a significant sign of water's presence on Ganymede. This announcement came after 20 years of the huge telescope's work of analyzing data of the previously mentioned moon.

The website stated on its official website: "Previous research has offered circumstantial evidence that Ganymede ...contains more water than all of Earth's oceans."

It added: "However, temperatures there are so cold that water on the surface is frozen solid. Ganymede's ocean would reside roughly 100 miles below the crust; therefore, the water vapor would not represent the evaporation of this ocean. Astronomers re-examined Hubble observations from the last two decades to find this evidence of water vapor."

The telescope's staff tweeted: "With Hubble data, astronomers found evidence of water vapor in the atmosphere of Jupiter’s icy moon Ganymede! Through sublimation (solid-gas), charged particles from the Sun turn ice into water vapor."

Ganymede is considered the biggest moon in the whole solar system and the ninth-largest object in the whole solar system.
