Discover Water Vapor on the Moon Ganymede – La Nouvelle Tribune

icy satellite JupiterAnd GanymedeIt is the largest moon in the solar system. But also the third order in terms of distance from the ‘Galilee Moons’ or ‘Galilee Moons’ from Jupiter. an interest Ganymede, according to research astronomers lies in the fundamental role that the Moon plays in the Galilee Satellite System and its unique magnetic and plasma interactions with Jupiter and its environment. But also in the fact that it provides a natural laboratory for the analysis of nature, evolution and the possibility of habitation in frozen worlds in general. In Monday’s publication in the scientific journal ‘“Nature Astronomy”, astronomers from NASA Connect their discovery.

Water vapor in the crisp atmosphere of a frozen moon…

This Monday, in their publication in the scientific journal NASA, the researchers outlined their discovery: atmospheric water vapor held by an icy moon. An important discovery, in that it gave scientists the basis for interesting work on the creation of life on planets and of course on the means of preserving it as much as possible. The apparent discovery of water vapor came after researchers compared two observations of Ganymede in 1998 to another round of observations made in 2018.

The team’s analysis combined data from two instruments: the Cosmic Origins Spectrometer of Hubble in 2018 and archive images from the Space Telescope Imaging Spectrometer (STIS) 1998-2010. An analysis that allowed scientists to understand that ice is on the surface GanymedeIce cream is produced at temperatures as low as -185 degrees CelsiusIt can evaporate under the influence of the sun. Water vapors were observed when the Sun’s influence was at its zenith on the planet, that is, around noon.

Suddenly, according to scientists, the observation of this phenomenon made it possible to better understand the Jovian system, the separation of its history, from its origin to the possible emergence of habitable environments and of course ” A better understanding of how gas giant planets and their satellites form and evolve Additionally, according to NASA. We hope that new information about habitability will be found in Jupiter-like exoplanet systems » Especially during the mission juice, which is scheduled to be launched in 2022. A large-scale research expedition fromEuropean Space Agency (which – which).
