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

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 explained from blackouts to stunning auroras as Nasa issues warning An X-class solar flare erupted from the Sun, causing a radio blackout across Europe, Asia, and the Middle East.

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