We trace the evolution of research on extreme solar and solar-terrestrial events from the
1859 Carrington event to the rapid development of the last twenty years. Our focus is on the …

Solar eruptive phenomena embrace a variety of eruptions, including flares, solar energetic
particles, and radio bursts. Since the vast majority of these are associated with the eruption …

Coronal mass ejections (CMEs) are the largest-scale eruptive phenomenon in the solar
system, expanding from active region-sized nonpotential magnetic structure to a much larger …

The heliosphere represents a uniquely accessible domain of space, where fundamental
physical processes common to solar, astrophysical and laboratory plasmas can be studied …

We present an overview of solar flares and associated phenomena, drawing upon a wide
range of observational data primarily from the RHESSI era. Following an introductory …

Significant new opportunities for astrophysics and cosmology have been identified at low
radio frequencies. The Murchison Widefield Array is the first telescope in the southern …

The Sun, as an active star, is the driver of energetic phenomena that structure interplanetary
space and affect planetary atmospheres. The effects of Space Weather on Earth and the …

Coherent radio bursts detected from M dwarfs have some analogy with solar radio bursts but
reach orders of magnitude higher luminosities. These events trace particle acceleration …

Global extreme-ultraviolet (EUV) waves are spectacular traveling disturbances in the solar
corona associated with energetic eruptions such as coronal mass ejections (CMEs) and …

Using the potential of two unprecedented missions, Solar Terrestrial Relations Observatory
(STEREO) and Reuven Ramaty High-Energy Solar Spectroscopic Imager (RHESSI), we …
