The Physics of Super Flares in Stars
The sun regularly releases solar flares that have the potential to impact Earth, causing disruptions like blackouts and interference with global communications. However, NASA's Kepler and TESS missions have identified a more formidable phenomenon — "Super flares." These intense flares emanate from stars 100–10,000 times brighter than our sun, surpassing the solar flares we typically observe.
Researchers Discover Aurora-Like Radio Signals Emanating Above a Sunspot
In an article featured in Nature Astronomy, astronomers affiliated with the Center for Solar-Terrestrial Research at the New Jersey Institute of Technology (NJIT-CSTR) have presented radio observations capturing a remarkable aurora-like phenomenon taking place at an altitude of 40,000 km above a relatively dim and cool area on the sun identified as a sunspot.
