What is the evidence for a liquid water ocean on Europa?
What is the evidence for a liquid water ocean on Europa?
Mounting Evidence for Water The measurements suggested to scientists that electrically conductive fluid, likely a salty ocean beneath Europa’s ice layer, was causing the magnetic disturbances. When researchers analyzed the magnetic disturbances more closely in 2018, they found evidence of possible plumes.
What is NASA doing to search for water on the moon?
NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA) has confirmed, for the first time, water on the sunlit surface of the Moon. This discovery indicates that water may be distributed across the lunar surface, and not limited to cold, shadowed places.
Why does NASA look for water?
Find out if life ever existed on Mars. NASA scientists will look for water and places where living things might use heat energy from under ground. They will also look for signs of carbon, which is an element needed for life as we know it.
Is there evidence of water on Saturn?
ESA’s Herschel space observatory has shown that water expelled from the moon Enceladus forms a giant torus of water vapour around Saturn. The discovery solves a 14-year mystery by identifying the source of the water in Saturn’s upper atmosphere.
What moon of Saturn has water?
moon Enceladus
Is the water on Enceladus drinkable?
The giant planets Neptune, Uranus, Saturn and Jupiter are the giants of the solar system. This may be the case inside Europa (Jupiter) and Enceladus (Saturn), but chemical reactions with the rock would make the liquid water salty, so not good to drink
Is there life on Saturn’s moon?
The sixth-largest moon of Saturn, this very bright, icy moon contains everything that astrobiologists consider is critical for life as we know it to exist—water, organic compounds and energy
How do you see Saturn and Jupiter conjunctions?
To see the great conjunction, go outside anytime this month shortly after sunset. Look for the two bright dots low in the southwest. Jupiter appears as a bright star, while Saturn is slightly less-bright with a yellow hue. Each day they drifted closer together until 21 December, when they almost appeared to touch.
What happens when Jupiter and Saturn align?
When they line up, their vibrations blend and work together. A Great Conjunction happens when Jupiter and Saturn align. Both planets are associated with authority, but each very differently.
Which planet is closest to the sun and which farthest?
The next-closest planet to the Sun is Venus, followed by Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. Nine planets orbit the Sun. Mercury is the closest and Pluto the farthest away.
