Why solar flares are way hotter than researchers thought
Summary
Researchers have found that solar flares are much hotter than previously believed, reaching temperatures up to 180 million degrees Fahrenheit. This discovery challenges earlier assumptions and could improve our understanding of solar flares, which may help in protecting satellites and astronauts.Key Facts
- Solar flares occur when magnetic energy is released and energizes particles like ions and electrons.
- Recent research shows that ions in solar flares could heat up more than previously thought, reaching temperatures over 100 million degrees Fahrenheit.
- This temperature is more than six times what scientists believed before.
- The new findings come from computer simulations and measurements taken in near-Earth space.
- Previous methods mainly focused on electron temperatures, assuming they were the same as ion temperatures.
- Improved understanding of solar flares can help protect satellites and astronauts from their effects.
- Scientists are developing new models to study how these flares evolve.
