A newly released time-lapse video captured from space has offered a breathtaking view of the Aurora Borealis, or Northern Lights, as seen from an entirely different perspective—high above the Earth’s atmosphere. The video, which has quickly gone viral, reveals the ethereal beauty of this natural phenomenon as it unfolds in a vibrant cosmic dance of light and color, highlighting the sheer grandeur of the auroras from outer space.
A View From Above: The International Space Station’s Stunning Footage
The time-lapse video was captured by astronauts aboard the International Space Station (ISS), which orbits the Earth at an altitude of approximately 250 miles. As the ISS orbits the planet, it occasionally passes over regions where the auroras are active, giving astronauts a rare and spectacular vantage point. The video shows the Northern Lights as shimmering waves of green, purple, and red light flickering over the Earth’s polar regions, offering an unparalleled perspective of the auroras in motion.
From space, the auroras appear as vast, glowing bands that wrap around the polar regions, illuminating the atmosphere in a soft, otherworldly glow. The colors, which are created by charged particles from the sun interacting with gases in Earth’s atmosphere, shift and change rapidly in the time-lapse video, creating a visual spectacle unlike any seen from the ground.
The Science Behind the Aurora Borealis
The Northern Lights occur when solar wind, which is a stream of charged particles emitted by the sun, collides with Earth’s magnetosphere. This collision excites gases in the atmosphere, such as oxygen and nitrogen, causing them to glow. The auroras typically appear as green, red, purple, and blue lights, with green being the most common color due to the interaction of the particles with oxygen at altitudes of around 60 miles.
What makes the time-lapse video so unique is that it captures the full extent of the auroras from above, allowing viewers to see the phenomenon in its entirety rather than just a segment of the sky. This provides valuable insight into the scale and reach of the auroras, which can stretch for thousands of miles across the Earth’s atmosphere.
A Cosmic Dance of Light
In the video, the auroras are seen flickering and moving in a wave-like motion, as if performing a cosmic dance. This movement is caused by fluctuations in Earth’s magnetic field, which guides the charged particles from the sun toward the poles, where they interact with the atmosphere. As the ISS moves at speeds of approximately 17,500 miles per hour, the time-lapse effect compresses several minutes of auroral activity into just a few seconds, amplifying the dynamic motion of the lights.
The vastness of the auroras is particularly striking in the video. From space, the lights can be seen curving along the Earth’s surface, outlining the curvature of the planet. The ISS’s orbit allows for multiple passes over the auroras, capturing them from different angles and lighting conditions as they shift and evolve over time.
The Significance of the Video
While ground-based views of the Northern Lights are always awe-inspiring, the time-lapse footage from space adds a new dimension to our understanding of this natural wonder. It demonstrates the scale and power of solar activity and how it interacts with Earth’s atmosphere, reminding us of the fragile boundary between our planet and the space beyond.
