For around half a century, scientists have been puzzled by the odd spectral lines produced by solar flares. Now we may have some answers.
Anew study looking at solar flares may have solved a 50-year-old mystery about our host star, finding that solar flares may be far hotter than we realized.

Solar flares are a common event on the Sun’s surface. They can be seen regularly throughout the year, and particularly during the solar maximum phase of the Sun’s cycle.

“A solar flare is an intense burst of radiation coming from the release of magnetic energy associated with sunspots. Flares are our solar system’s largest explosive events. They are seen as bright areas on the Sun and they can last from minutes to hours,” NASA explains...
