The Daniel K. Inouye Solar Telescope, the largest solar telescope on Earth, has resolved features as small as 30 km on the Sun's surface, 150 million km away. Texas-sized granules on a boiling face, magnetic threads just 20 km wide. SORABUMI explains how a ground-based instrument managed to see that clearly.
A Japanese research team has pinpointed a massive solar storm that struck around 1200–1201 CE. The evidence comes from two sources: a sharp spike in carbon-14 trapped in the rings of a buried tree from northern Japan, and a line in the medieval diary of poet Fujiwara no Teika describing 'a red light in the northern sky.'
