A research team led by Dr. Shen Jinhua from the Xinjiang Astronomical Observatory (XAO) of the Chinese Academy of Sciences has investigated rapid spatiotemporal vertical electric currents (VECs) ...

A powerful X-class solar flare erupted on June 19, disrupting radio signals and potentially setting the stage for geomagnetic storms and rare aurora sightings.

An active region of the Sun, known as sunspot 4114, has just produced an X1.9-class flare. This event, which occurred on June 19, had an impact on Earth and our communications. X-class solar flares ...

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.

Solar flares can affect us on Earth, and radiation from this flare caused a shortwave radio blackout. A map released by the ...

Another X-class solar flare triggers US communication blackouts as the sun continues to emit intense solar flares during the solar maximum.

What is an X-class solar flare detected by NASA Solar flares are powerful bursts of radiation from the Sun, and X-class flares are the strongest among them.

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