Evidences of 💧WATER in outer space

"We found water vapor, a salty reservoir and organic from Enceladus’s polar jets"

  • Although it was ‘very exciting to find these organics’, it is not yet possible to say whether they were formed by living things or not, she explains. ‘The instrument doesn’t have a way to make that distinction, we need to go back with more powerful mass spectrometers, going out to a much larger range that could look for large-chain parent molecules such as amino acids and fatty acids.’

  • Other energizing discoveries in the crest information where the abundance of hydrogen and the location of small grains of nanosilica, which can just shape in high temp water.

  •  'Those two snippets of data together indicated proof of aqueous vents on the ocean bottom of Enceladus,' says Spilker.


  • Aqueous vents structure at areas where seawater meets magma. Water goes down splits into the center, is warmed and after that returns out again in power.

Europa

  • The gas giant Jupiter, the next planet beyond Mars in the solar system, is inhospitable to life in any currently imaginable form. But its icy moons – especially Europa – have potential. 
  • A number of missions have flown past Jupiter and its moons on route to other places, but Nasas Galileo mission was the first designed to specifically orbit the planet and study its moons. It collected images and data in the Jovian system from 1995 to 2003, passing Europa 12 times.

  • Pictures and data collected by this spacecraft suggest that Europa has a layered structure like Earth: an iron-rich core, a rocky mantle and a crust of ice. 

  • Magnetic field measurements found an electric current inside, consistent with a salty liquid ocean beneath the thick crust of ice around the whole planet. Photographs showing huge cracks in the ice, taken by the same mission, support this idea.

  • The Hubble Space Telescope also detected water vapor above Europa’s South Pole and it was proposed this came from erupting water plumes.
