Abstract

This review is focused on recent {\sl Self-Organized Criticality (SOC)} literature of astrophysical phenomena, covering the last decade of (2015-2025), while previous SOC literature (1987-2014) is reviewed elsewhere. The selection of literature is mostly based on searches with the NASA-supported {\sl Astrophysics Data System (ADS)}. The discussed astrophysical SOC phenomena are subdivided into solar flares, solar atmosphere (photosphere, chromosphere, corona), heliospheric systems (coronal mass ejections, solar wind, solar energetic particles), planetary systems (asteroids and small bodies, lunar cratering, Saturnian ring systems, magnetospheric systems), stellar flares, and galactic systems (pulsar glitches, gamma ray bursts, soft gamma-ray repeaters, supergiant fast X-ray transients, fast transient radio bursts, magnetars, blazars, black holes).
