Astronauts orbiting Earth aboard of the International Space Station sometimes witness incredible phenomena happening on our planet that are invisible to us!
This intense lightning storm filmed over Houston is one of these amazing moments.

These hypnotic lightning flashes from within a thunderstorm above Houston, Texas were captured by US astronaut Reid Wiseman from the ISS on June 27, 2014.
As you know, the lightning phenomenon remains mysterious and some even entirely unclear (“sprites,” “blue jets” and “elves”) to scientists.
