NASA cameras capture huge solar flares


NASA cameras captured images of what the agency is calling at least two "significant" solar flares. The first one peaked at 7:42 a.m. ET Tuesday, followed by a second, lesser blast at 8:52 a.m. ET.

The short-lived explosions were expected to disrupt high-frequency radio communications on Earth, although NASA scientists said they pose no threat to humans. Even with all its power, the sun doesn't have enough energy to hurl a fireball 93 million miles at the Earth.

Solar flares are powerful bursts of radiation that send gases, plasma and other matter into the solar system. Harmful radiation from a flare cannot pass through Earth's atmosphere to affect humans, but when intense enough, the explosions can disturb GPS and communications signals, NASA said.
