The Voyager spacecraft have left the heliosphere and entered the interstellar medium,
making the first observations of the termination shock, heliosheath, and heliopause. New …

A detailed overview of the knowledge gaps in our understanding of the heliospheric
interaction with the largely unexplored Very Local Interstellar Medium (VLISM) are provided …

The solar wind (SW) and local interstellar medium (LISM) are turbulent media. Their
interaction is governed by complex physical processes and creates heliospheric regions …

In situ observations of interstellar neutral (ISN) helium atoms by the IBEX-Lo instrument on
board the Interstellar Boundary Explorer (IBEX) mission are used to determine the velocity …

Nearly incompressible magnetohydrodynamic (NI MHD) theory for β∼ 1 (or β≪ 1) plasma
has been developed and applied to the study of solar wind turbulence. The leading-order …

Past analysis has shown that the heliosphere structure can be deduced from correlations
between long-scale solar wind pressure evolution and energetic neutral atom emissions …

Jupiter's moon Europa has a predominantly water-ice surface that is modified by exposure to
its space environment. Charged particles break molecular bonds in surface ice, thus …

Interstellar pickup ions are an ubiquitous and thermodynamically important component of
the solar wind plasma in the heliosphere. These PUIs are born from the ionization of the …

Water‐group gas continuously escapes from Jupiter's icy moons to form co‐orbiting
populations of particles or neutral toroidal clouds. These clouds provide insights into their …

Abstract Interstellar neutrals (ISNs), pick-up ions (PUIs), and energetic neutral atoms (ENAs)
are fundamental constituents of the heliosphere and its interaction with the neighboring …
