A spectacular Southern Lights display has been captured on camera from space.
Nasa astronaut Jessica Meir filmed the timelapse from onboard the SpaceX Dragon shuttle.
The Southern Lights are just as common as the Northern Lights, and regularly take place over Antarctica, but relatively few people live in latitudes close to the South Pole, so they are not as well-known as their northern counterpart.
These lights occur near the poles because Earth's magnetic field channels charged particles from the Sun toward those regions, where they collide with the atmosphere and create shimmering waves of colour.
