Solar flares can impact radio communications and pose risks to spacecrafts and astronauts, according to NASA.

The strongest solar flare in over six years erupted from the sun Thursday afternoon, causing radio blackouts here on Earth, primarily in South America. Within the next couple of days, solar ...

Only 12 flares more powerful than X10-class have ever been recorded. The most powerful solar flare of this solar cycle so far occurred on October 3, hitting X9.0-class in strength.

Solar flares are intense bursts of radiation coming from the sun. They are the most powerful explosions in our solar system, according to NASA. The biggest solar flares are labeled as X-class flares.

On Oct. 3, the sun released the most powerful solar flare this solar cycle, a colossal X9.05 eruption — and it's heading for Earth.

This week, the sun let out a powerful solar flare - the most powerful since 2017, and among the most powerful recorded to date.

The sun spit out the largest solar flare in more than a decade on Tuesday, though after a week of being pummeled by plasma, the Earth could be in the clear this time.

The strongest solar flare in half a decade just launched off the sun from the same sunspot group that triggered dazzling auroras last weekend. But don't expect northern lights this time around.

A hyperactive sunspot recently unleashed its third X-class flare in under 24 hours. The X6 flare is the most powerful since 2017 and could be followed by equally massive explosions.
