New Study Finds Solar Flares Hotter Than Ever Estimated
US · Published Sep 12, 2025
New study suggests solar flares can reach over 100 million degrees Fahrenheit, 6.5 times hotter than previously estimated.
Intense solar flares can disrupt satellites, power grids, and radio signals, while also creating auroras.
The findings necessitate a reevaluation of space weather models and strategies to protect critical infrastructure.
New research reveals intense solar flare temperatures
New research indicates that solar flares might be more intense than previously thought, potentially reaching temperatures over 100 million degrees Fahrenheit, which is 6.5 times hotter than earlier estimations. These flares, originating from the Sun's outer atmosphere, are powerful bursts that can severely impact our technology and environment. The consequences of such intense solar activity include the disruption of satellites, potential blackouts in power grids, and disturbances in radio signals. Furthermore, these flares contribute to the creation of auroras, showcasing both the destructive and beautiful aspects of space weather.
