Two gigantic solar flares erupting from the sun have been recorded by NASA.
The space agency has said the resulting solar storm could strike Earth tomorrow and may disrupt satellites and cause power outages in some places.
However, the charged particles that make up the solar storm could create stunning views of the Northern Lights as they interact with our atmosphere.
Timing is a crucial factor.
The arrival of the solar storm coincides with the formation of 'equinox cracks' in Earth's magnetic field, which form around the equinoxes on March 20 and September 23 each year.
