A breathtaking timelapse video has been released by NASA, offering a unique perspective on the Southern Lights from 400km above Earth. Captured by astronaut Jessica Meir aboard the International Space Station (ISS), the footage is a mesmerising display of vibrant, dancing lights that illuminate the atmosphere.
The aurora australis is a natural light show predominantly seen in high-latitude regions around Antarctica. Its northern counterpart, the aurora borealis or Northern Lights, can be spotted in areas such as Scandinavia, Canada, and parts of Scotland.
The display occurs when charged particles from the sun collide with gases in Earth's upper atmosphere, exciting atoms and molecules to emit light. The resulting colours depend on the type of gas involved and the altitude at which the interaction takes place.
This remarkable footage adds to a growing collection of imagery and data gathered by the ISS as it orbits our planet. Such visualisations captivate audiences worldwide while contributing to scientific understanding of space weather's effects on Earth's atmosphere and technological systems.
Witnessing auroras from space provides invaluable context for researchers studying atmospheric physics and solar-terrestrial interactions. The clarity and scope of Meir's timelapse offer insights that ground-based observations often cannot, enhancing our appreciation and comprehension of these powerful celestial events.
