Don’t Touch: How Scientists Study the Reactions Inside Stars

Right: SOHO-EIT image from 14 September 1997 showing a huge eruptive prominence in the resonance line of singly ionized helium (He II) at 304 Angstroms in the extreme ultraviolet. The material in the eruptive prominence is at temperatures of 60,000 - 80,000 K, much cooler than the surrounding corona, which is typically at temperatures above 1 million K.
