Physicist’s magnetic device discovered saltwater ocean on Europa Moon (the smallest of the four Galilean moons orbiting Jupiter). The data has collected Margaret Kivelson and her team of physicists.
“It was December 1996, and the spacecraft Galileo had just flown by Europa, an icy moon of Jupiter. The readings beamed back to Earth suggested a magnetic field emanating from the moon. Europa should not have a magnetic field, yet there it was — and not even pointed in the right direction”, states www.dispatch.com.
″This is unexpected, ″ Margaret Kivelson recalled saying as the weird data rolled in. ″And that’s wonderful”. The results are very important and surprising for Kivelson’s team.
The team had devised the magnetometer that had returned the anomalous data. And then Kivelson and her team would soon prove that they had discovered the first subsurface, saltwater ocean on Europa moon.
Kivelson is a professor emerita of space physics at the University of California, Los Angeles. She will turn 90 this month, and for 40 years, she has been an active part of almost every major NASA voyage beyond the asteroid belt.
[Most recently, Kivelson has been an investigator working on the plasma instrument for the Europa Clipper, NASA’s next great voyage to the outer solar system. Scheduled to launch in 2022, the spacecraft will study the habitability of Europa, Jupiter’s ocean moon. Kivelson’s work will help answer whether life could be there by determining the ocean’s depth and salinity, among other features].
About Europa Moon
Europa is the smallest of the four Galilean moons orbiting Jupiter, and the sixth-closest to the planet. It is also the sixth-largest moon in the Solar System. The moon was discovered in 1610 by Galileo Galilei which was named after Europa (the legendary mother of King Minos of Crete and lover of Zeus).
