Jupiter "Europe" moon from water vapor
The moon of Jupiter, Europe, finally confirmed the presence of water in the form of water vapor. NASA has confirmed that there is water vapor on Jupiter's Europe satellite, CNET IT media reported today.
Meanwhile, scientists have predicted the possibility of a sea of water under the thick ice of Europe. In particular, in 1979, Voyager was believed to have formed the sea under a thick layer of ice, capturing a myriad of cracks in the surface of the ice, like blood snow. However, in the last 40 years, the presence of water has not been confirmed by direct observation. We also see giant eruptions that look like water vapor in Europe, but we can't prove that they contain real water.
According to NASA, the team led by Dr. Lucas Paganini, a planetary scientist at the Goddard Space Flight Center, was able to fill the Olympic pool in minutes with the latest issue of Nature Astronomy magazine. It was confirmed that it ejected a quantity of water (2,360 kg per second).
Researchers say the steam eruptions are rare enough to be captured only once during the 17 observation nights in 2016-2017, but are sufficient to capture from Earth.
Europe is one of the four largest moons of 79 Jupiter satellites, first discovered by Galileo Galilei in 1610. In 2013, the Hubble Space Telescope captured the hydrogen and oxygen atoms that make up water molecules (H₂O) in Jupiter's atmosphere. and a few years later, when Europe passed in front of Jupiter, a vapor column was captured, proving its existence. There was no conclusive evidence. The steam observations support the hypothesis that there could be twice as many oceans under Europe's ice layer, several kilometers thick.
It seems that we will have to wait a little longer to completely solve the mystery of Europe. NASA will send a spacecraft on the Europa Clipper mission in mid-2020 to explore life-sustaining water.
The team predicted that if Europa Clipper were launched in the mid-2020s, it could orbit Europe's orbits to capture water vapor images and analyze mass samples found in the atmosphere by mass spectrometry. Europa Clipper will also find a place for future landings to settle and collect samples.
