X2.7-class eruption from sunspot AR4087 disrupts radio signals as the active region rotates toward Earth, raising the risk of more flares ahead.

A colossal solar storm just blasted Earth, causing radio blackouts across five continents — and experts warn this fiery space weather may only be the beginning.

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

The Earth-directed X-flare action was captured by NASA's Solar Dynamics Observatory.
