The solar fireworks at the weekend were recorded by several satellites, including Nasa’s new Solar Dynamics Observatory which watched its shock wave rippling outwards.
Astronomers from all over the world witnessed the huge flare above a giant sunspot the size of the Earth, which they linked to an even larger eruption across the surface of Sun.
The explosion was aimed directly towards Earth, which then sent a “solar tsunami” racing 93 million miles across space.
Images from the SDO hint at a shock wave travelling from the flare into space, the New Scientist reported.
Experts said the wave of supercharged gas will likely reach the Earth on Tuesday, when it will buffet the natural magnetic shield protecting Earth.
It is likely to spark spectacular displays of the aurora or northern and southern lights.
Scientists have warned that a really big solar eruption could destroy satellites and wreck power and communications grids around the globe if it happened today.
