Multifractal structure of the large-scale heliospheric magnetic field strength fluctuations near 85AU [PDF]

Nonlinear Processes in Geophysics, 2004
During 2002, the Voyager 1 spacecraft was in the heliosphere between 83.4 and 85.9AU (1AU is the mean distance from the Sun to Earth) at 34° N heliographic latitude.

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

Experimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Mercury's Alfvén Wing Current System Under Sub‐Alfvénic Solar Wind Conditions: Insights From Global MHD Simulations

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Mercury's proximity to the Sun results in the lowest average Alfvénic Mach number in the upstream solar wind compared to any other planet. Under extreme conditions, the upstream Alfvén speed can exceed the solar wind speed, resulting in a sub‐Alfvénic interaction in which standing Alfvén wings form.

Multifractal two-scale Cantor set model for slow solar wind turbulence in the outer heliosphere during solar maximum [PDF]

Nonlinear Processes in Geophysics, 2011
To quantify solar wind turbulence, we consider a generalized two-scale weighted Cantor set with two different scales describing nonuniform distribution of the kinetic energy flux between cascading eddies of various sizes.

Mercury's Eccentric Orbit as a Driver of Significant “Seasonal” Change in Upstream Solar Wind Forcing

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Mercury experiences the most intense and variable solar wind (SW) conditions in the solar system due to its close, eccentric orbit about the Sun. In addition to variation driven by coronal source and solar cycle, the SW arriving at Mercury varies periodically as the planet's heliocentric distance changes by over 50% per orbit.

The Passage of the Solar System through the Edge of the Local Bubble

The Astrophysical Journal
The Sun moves through the interstellar medium (ISM) at a velocity of ∼19 pc Myr ^−1 , making the conditions outside the solar system vary with time over millions of years.

Particle Acceleration on the Sun and in the Heliosphere [PDF]

Symposium - International Astronomical Union, 2001
Examples of the acceleration of energetic ions and electrons are given for the Sun, the middle heliosphere, and the outer heliosphere. The characteristics of the acceleration are revealed only after the effects of energetic particle propagation are understood.

Plasma Stability in Turbulent Magnetic Flux Ropes Downstream of a Collisionless Shock

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract How pre‐existing solar wind turbulence, and coherent structures such as magnetic flux ropes within it, influence the transition of plasma across a shock is still poorly understood. Recently, in situ observations from the Earth's magnetosheath have been used to study plasma stability against ion kinetic instabilities. In the turbulent flow, the

The Heliosphere through the Solar Activity Cycle

, 2008
Understanding how the Sun changes though its 11-year sunspot cycle and how these changes affect the vast space around the Sun – the heliosphere – has been one of the principal objectives of space research since the advent of the space age.

A solar storm observed from the Sun to Venus using the STEREO, Venus Express, and MESSENGER spacecraft [PDF]

, 2009
The suite of SECCHI optical imaging instruments on the STEREO-A spacecraft is used to track a solar storm, consisting of several coronal mass ejections (CMEs) and other coronal loops, as it propagates from the Sun into the heliosphere during May 2007 ...
