Space physics explores the dynamic environment surrounding our planet and the wider solar system, focusing on how charged particles, magnetic fields, and solar winds interact with celestial bodies. This field helps us understand phenomena like auroras, space weather that can disrupt satellites, and the fundamental behavior of plasma in the vacuum of space. It bridges the gap between astronomy and particle physics, revealing the invisible forces that shape our cosmic neighborhood.

This paper introduces EMBER, an open-source machine-learning pipeline that successfully automates the detection of modulated ion acoustic waves in Parker Solar Probe data, achieving high accuracy while confirming their role in driving core-electron heating without relying on temperature data for identification.
This study statistically analyzes 39 multipoint ICME events observed between 2016 and 2023 to reveal that shock acceleration efficiency for energetic particles consistently increases with heliocentric distance up to 0.7 au before declining at greater distances.
This review synthesizes observational findings from the IRIS mission regarding the morphology, dynamics, and heating mechanisms of solar transition region loops, highlighting their distinct nature from coronal loops and outlining critical future research directions to better understand energy and mass transport in the solar atmosphere.
This study demonstrates that real-time observations from Solar Orbiter, positioned far upstream at 0.53–0.60 au, can successfully predict the magnetic structure and geomagnetic impact of coronal mass ejections with significantly improved lead times compared to current L1-based capabilities, validating the potential of far-upstream monitors for enhanced space weather forecasting.
This paper reports the first observation of three very-near-Earth reconnection events occurring within a single storm main phase, demonstrating that these frequent, pre-midnight phenomena drive energetic particle injections and magnetic dipolarizations essential for powering the ring current.
This paper introduces a physically-informed fuzzy clustering method using an expectation-maximization algorithm and modified Bayesian information criterion to automatically determine the optimal number of tracks and separate vertical sounding ionograms, even under disturbed ionospheric conditions, by incorporating adaptive noise filtering and extraordinary mode removal.
This paper provides a pedagogical overview of state-of-the-art cosmic ray-magnetohydrodynamics (CR-MHD) modeling on galactic scales, identifying systematic pitfalls in traditional assumptions while highlighting recent theoretical and observational progress in connecting micro-to-macro scales to better constrain cosmic ray transport and its impact on galaxy formation.
This study presents the first multipoint analysis of magnetohydrodynamic turbulence within the October 2024 extreme solar storm using four spacecraft at the L1 point, revealing significant spatial variability and differing turbulence maturity across mesoscale separations that underscore the complex role of internal processes and shock interactions in ICME evolution and space weather impacts.
This paper presents multi-spacecraft observations demonstrating that precursor interplanetary coronal mass ejections (ICMEs) located beyond 1 AU can reflect impulsive solar energetic electrons back toward the Sun, creating hazardous counter-streaming beams that pose a previously unidentified radiation risk for astronauts exploring deep space.
This paper presents the first batch of spin period measurements for 2,321 asteroids derived from Euclid Ecliptic Survey data, successfully determining 889 high-quality periods (including 16 candidate super-fast rotators) and establishing a robust pipeline that validates its accuracy against existing literature while providing an open-access catalogue for the majority of objects previously lacking period data.
