Small-scale and transient extreme ultraviolet kernels in solar flare ribbons

Astronomy & Astrophysics
Aims. Flare ribbons form when energy released by coronal magnetic reconnection is deposited in the low layers of the solar atmosphere. Therefore, by studying the dynamics of flare ribbons, one obtains an indirect measurement of reconnection in the corona.

Benchmarking Deep Learning Models for Real‐Time Prediction of Post‐Peak Solar Flare Irradiance Using FISM2 Data

Space Weather, Volume 24, Issue 9, September 2026.
Abstract This study presents a deep learning framework for real‐time prediction of post‐peak solar flare irradiance. The model targets the soft X‐ray band (0.1–0.8 nm) and three extreme ultraviolet (EUV) wavelength bands (9.0–9.9 nm, 13.0–13.9 nm, and 30.0–30.9 nm), and produces forecasts at 1‐min cadence for 3 hr after the flare peak.

Study of Reconnection Dynamics and Plasma Relaxation in MHD Simulation of a Solar Flare

Self-organization in continuous systems is associated with dissipative processes. In particular, for magnetized plasmas, it is known as magnetic relaxation, where the magnetic energy is converted into heat and kinetic energy of flow through the process ...

Did Space Weather Delay the 10:05 p.m. Train Departure From Exeter on 18 October 1841?

Space Weather, Volume 24, Issue 9, September 2026.
Abstract Although the Carrington Event of 1859 is typically cited as the first extreme space weather event of the scientific era, it is not the earliest example of modern human technology being impacted by geomagnetic activity. The literature includes reliable accounts of disturbances to telegraph equipment during geomagnetic storms dating to the late ...

Personalization and Fortification of In‐Space Manufactured Emulsified Beverages for Long‐Term Space Travel

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 5, September 2026.
ABSTRACT The current trend of individualized food items (nutrient content and flavor) can be particularly valuable to support people's health and well‐being in isolated environments where access to fresh foods and diverse nutrition is difficult. At the same time, bioactive compounds and micronutrients can be employed to countermeasure any health ...

Green Defence in the Racial‐Colonial Anthropocene: Militarized Twin Transitions and the Necropolitics of ‘Conflict‐Free’ Mineral Securitization in Eastern Congo

Antipode, Volume 58, Issue 5, September 2026.
ABSTRACT This article argues that powerful Western militaries are central architects of the necropolitics underpinning contemporary green and digital transitions. As climate change is increasingly framed as a security threat, NATO, the United States and the European Union pursue climate‐resilient defence infrastructures whose material foundations ...

Disentangling Thermal and Abundance Characteristics in a Solar Flare Using SDO/AIA, Hinode/XRT, and MinXSS-1 Observations

The Astrophysical Journal
We investigate the thermal properties of a solar flare by the observations of the soft X-ray Telescope on board Hinode and the Atmospheric Imaging Assembly (AIA) on board the Solar Dynamics Observatory. Our analysis reveals a tenuous but hot plasma cloud

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

Experimental Physiology, Volume 111, Issue 9, Page 4015-4040, 1 September 2026.
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 ...
