Jupiter's moon Europa has an ice shell about 18 miles thick — and that could be bad news for alien life
Using data gathered by NASA's Juno Jupiter orbiter, scientists estimate that Europa's ice shell is about 18 miles thick — which could make it hard for nutrients to get down to its buried ocean.
Europe, one of Jupiter's faithful companions, is potentially considered a place of extraterrestrial life. For this purpose, the bottom of the vast sea under the moon's ice crust has now been investigated.
Europa’s ice thickness and subsurface structure characterized by the Juno microwave radiometer
Jupiter’s moon Europa is thought to harbour a saltwater ocean beneath a variously disrupted ice shell, and it is, thus, one of the highest priority astrobiology targets in the Solar System. Estimates of the ice-shell thickness range from 3 km to over 30 km, and observations by the Galileo spacecraft indicated widespread regions of ice disruption (chaotic terrain) leading to speculation that the ice shell may contain subsurface cracks, faults, po…

Europa’s Ice Shell is Much Thicker than Previously Thought
New microwave measurements from NASA’s Juno spacecraft reveal Europa’s ice shell may stretch nearly 29 km (18 miles) deep, reshaping planetary scientists’ understanding of how the icy moon’s hidden ocean might exchange life-giving chemicals with the surface.

Juno Measures The Thickness Of Europa’s Ice Shell - Astrobiology
Results from the solar-powered spacecraft provide a new measurement of the thickness of the ice shell encasing the Jovian moon’s ocean. Data from NASA’s Juno mission has provided new insights into the thickness and subsurface structure of the icy shell encasing Jupiter’s moon Europa. Using the spacecraft’s Microwave Radiometer (MWR), mission scientists determined that the […] The post Juno Measures The Thickness Of Europa’s Ice Shell appeared fi…
