Watch the Sun unleash three powerful X-class solar flares in rapid succession

NASA's Solar Dynamics Observatory recently recorded a rare triple event of X-class solar flares. This video showcases these intense solar outbursts across multiple ultraviolet wavelengths, providing a unique look at the complex, multi-layered structure of the Sun's atmosphere.

Between February 21 and 22, 2024, the Solar Dynamics Observatory (SDO) observed three distinct X-class flares. These events are captured in the video using various blends of extreme ultraviolet light, such as 131, 171, 304, and 1600 angstroms. By combining these specific wavelengths, researchers can isolate different solar features and plasma temperatures.

The 131-angstrom wavelength is particularly useful for observing the Sun's activity, as it reveals both cooler plasma at 400,000 Kelvin and the extremely hot plasma associated with flares, which can reach between 6 and 10 million Kelvin. This multi-wavelength approach allows scientists to visualize the dynamic layers of the solar surface and corona during high-energy events.
