Description
Outgassing from plumes might enhance the neutral density in Europa’s atmosphere locally and affect the electromagnetic interaction of the moon. In the last seven years, various studies have claimed evidence for plumes erupting from Europa’s surface using a variety of methods from remote-sensing observations from Earth to in-situ plasma measurements. We discuss the studies claiming such plume evidence and compare the results in terms of derived plume properties such as location, density or duty cycle. We also discuss the general advantages and disadvantages of the different methods. Finally, we look at ongoing and future remote sensing programs and elaborate on the prospects for JUICE and Europa Clipper.
