NASA's Solar Dynamics Observatory captured sunspot AR3386 blast a long-duration X1.6-class solar flare and X1 flare. See time ...

When sunspots erupt at nearly the same time, it could be something known as "sympathetic solar flares." A double eruption ...

The latest solar flare follows an M-class one, the second-highest on the scale, that occurred days earlier on June 15. It caused a shortwave radio blackout across North America, with a loss of signal ...

The awe-inspiring moment that a powerful solar flare erupted from the sun earlier this week has been captured by NASA. The space agency’s Solar Dynamics Observatory spotted the super hot stre… ...

Solar flares can last mere minutes, or can drag on for hours, depending on their intensity. NASA classifies solar flares based on their strength, with B-class being the smallest and X-class ...

NASA’s Solar Dynamics Observatory saw a powerful “X1-class” solar flare that caused a radio blackout for 30 minutes as the sun's activity continues to increase.

NASA says that Solar Cycle 25 is already exceeding predictions. As a result, the space agency says that solar flares will increase over the next few years. And that it could cause some problems ...

The video, taken by NASA's Solar Dynamics Orbiter, shows mesmerizing close-up views of solar flares blasting off the sun between Monday and Thursday (Oct. 25-28), ending with a major X1-class ...

X-class flares also have the potential to create global transmission problems and world-wide blackouts, NASA says. New Year's Eve solar flare is strongest in 6 years.

NASA’s Solar Dynamics Observatory (SDO) has captured footage of a rare quadruple solar flare eruption. The eruption began around 1 a.m. on Tuesday, April 23. The near-simultaneous outbursts ...

NASA's Solar Dynamics Observatory captured this image of a solar flare — as seen in the bright flash in the upper right portion of the image — on March 31, 2022. (Image credit: NASA) ...
