Space Weather, Volume 24, Issue 6, June 2026.Abstract Ejections of magnetized plasma from the Sun, known as coronal mass ejections, can drive major geomagnetic activity if Earth‐directed, and are therefore monitored by space weather forecasters. The current focus being the forecast of the arrival time of a coronal mass ejection at Earth and the level of geomagnetic impact.

Using hydrogen energetic neutral atoms to study the heliosphere [PDF]
, 2021 The interaction between the solar wind and the partially ionized gas of the local interstellar medium (ISM) creates a bubble known as the heliosphere. Classically, the shape of the heliosphere has been regarded as comet-like, with a long tail pointed in ...

Solar Energetic Particle Forecasting With Multi‐Task Deep Learning: SEPNET
Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.Abstract Solar energetic particle (SEP) events pose severe threats to spacecraft, astronaut safety, and aviation operations. Accurate SEP forecasting remains a critical challenge in space weather research as a result of their complex origins and highly variable propagation.

Eos, Transactions American Geophysical Union, 1991 Coronal mass ejections (CMEs) are playing increasingly important roles in models developed to understand solar‐terrestrial physics. A CME is characterized by a disruption or change in a helmet streamer, one of the radiant petals so prominent in solar eclipse pictures.

Signatures of Reconnection and a Split Heliospheric Tail in High-energy Energetic Neutral Atoms
The Astrophysical JournalThe shape of the heliosphere, regarded as comet-like since the 1960s, has recently been the subject of intense debate in the last decade. There is disagreement as to whether the heliospheric tail extends to ∼10,000 au in a comet-like shape or if it is ...

Solar Energetic Particle Prediction in the Inner Heliosphere Using Deep Learning and PSP/IS⊙IS Data
Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.Abstract Solar events, such as coronal mass ejections and solar flares, accelerate large numbers of energetic charged particles, producing solar energetic particle (SEP) events that can harm astronauts, damage satellites, and potentially damage infrastructure on Earth.

3D pressure-corrected ballistic extrapolation of solar wind speed in the inner heliosphere
Journal of Space Weather and Space ClimateSolar wind parameters at different locations in the inner heliosphere can be estimated using various solar wind extrapolation methods. The simple ballistic method extrapolates solar wind parameters from the point of measurement to a chosen heliospheric ...
