Watch sunspot region 4114 erupt with its most powerful solar flare yet. The X1.9 class flare triggered radio blackouts across the Pacific Ocean.

It was an X-class flare — the most intense kind, NASA said. Solar flares are essentially "giant explosions on the sun" that send energy, light and high-speed particles into space, according to NASA.

NASA captured an image of the sun emitting a powerful solar flare that could interfere with technology on Earth.

The M-class flare was accompanied by a coronal mass ejection currently forecast to land Earth with a glancing blow on June 18.

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

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.

The sun has had quite a busy week hurling solar flares at our planet, causing blackouts across the globe. “After weeks of calm, solar activity is suddenly high again,” reports Spaceweather.com ...

A strong solar flare erupted from the sun's surface, impacting radio transmissions on Earth's sunlit side on Tuesday.

Watch the sun erupt with an X2.7-class flare on May 14, causing radio blackouts across Europe and Asia. More solar activity could be on the way.

NOAA: A strong X1.2 solar flare erupted, raising the risk of geomagnetic storms, northern lights and possible technological disruptions. Here's what to know.

As the sun reaches its solar maximum, a strong solar flare erupted on March 28, which may enhance the visibility of the northern lights and disrupt technology.

Solar flares are bursts of radiation from the sun’s surface, sometimes followed by a bubble of magnetized plasma particles called a coronal mass ejection (CME). If they happen to spray out in ...
