Old NASA spacecraft points to new evidence of watery plumes over Europa

Old NASA spacecraft points to new evidence of watery plumes over EuropaA fresh look at data from a 1997 flyby of Jupiter’s moon, Europa, suggests that NASA’s Galileo spacecraft flew directly through a watery plume, raising hopes of probing the jets for signs of life around the second planet from Earth. The revelations Monday came after scientists revisited a puzzling reading from an instrument aboard Galileo, which in 1995 became the first spacecraft to enter the orbit of a gas giant planet. What they found was the most direct evidence yet of plumes emerging from Europa’s frozen surface, researchers reported in the scientific journal Nature Astronomy.
