As ridiculously huge balls of burning hydrogen tend to do from time-to-time, the Sun occasionally throws off huge bursts of radiation and charged particles in a coronal mass ejection (CME).
And sometimes those CMEs are thrown towards Earth.
In fact these happen all the time - and usually cause few problems on Earth except some communications interference - despite the possibility that one day they might pose a bigger problem to infrastructure.
One of the most recent occurred on 17 March, when an M1-class solar flare erupted from sunspot AR1692, which larger than our planet, and hurtled towards the Earth.

His amazing time-lapse film captures 2464 views of the sky during the resulting aurora. It's an inspiring reminder of how small we are compared to the universe.
