'X-class' solar flares caught on film
Images released by Nasa show the Sun releasing two "significant" solar flares on Tuesday.
Nasa's Goddard Spaceflight Centre said the flares were classified as "X-class", which is the most intense type.
Nasa says that solar flares pose no direct threat to the Earth, but very intense ones can potentially disrupt GPS and other communications signals.
