Abstract The Interstellar Mapping and Acceleration Probe (IMAP) is a revolutionary mission
that simultaneously investigates two of the most important overarching issues in …

The exploration of interplanetary space and our solar bubble, the heliosphere, has made a
big leap over the past two decades, due to the path-breaking observations of the two …

The long-anticipated encounter by Voyager 2 (V2) of the region between the heliosphere
and the very local interstellar medium (VLISM) occurred toward the end of 2018. Here, we …

Abstract NASA's Interstellar Boundary Explorer (IBEX) mission has operated in space for a
full solar activity cycle (Solar Cycle 24), and IBEX observations have exposed the global …

The classic accepted view of the heliosphere is a quiescent, comet-like shape aligned in the
direction of the Sun's travel through the interstellar medium (ISM) extending for thousands of …

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 …

Abstract The Interstellar Boundary Explorer (IBEX) mission has shown that variations in the
energetic neutral atom (ENA) flux from the outer heliosphere are associated with the solar …

For more than five decades, the shape and interactions of the heliosphere with the local
interstellar medium have been discussed in the context of two competing models, posited in …

As a sharp feature in the sky, the ribbon of enhanced energetic neutral atom (ENA) flux
observed by the Interstellar Boundary Explorer (IBEX) mission is a key signature for …

Observations with the Interstellar Boundary Explorer (IBEX) have shown enhanced
energetic neutral atom (ENA) emission from a narrow, circular ribbon likely centered on the …
