If you've ever seen auroras in the night sky, then you are one of the lucky few who has enjoyed a view of one of nature's most colorful and spectacular phenomena. But for the very lucky, very few who've seen auroras from space, the view is on a whole other level!
What is it?
When charged particles streaming constantly from the sun, also known as the solar wind, reach Earth and interact with our atmosphere, it creates what we call auroras. Seeing these spectacular, colorful displays in the sky is on many people's bucket list, as auroras can light up the sky in a rainbow of colors. But this beautiful phenomenon happening in our atmosphere can also be seen from space.
European Space Agency astronaut Sophie Adenot, who is currently aboard the International Space Station as part of the εpsilon mission, spotted the aurora australis, or auroras over the Southern Hemisphere. (Lights in the Northern Hemisphere are known as the aurora borealis.)
And the image she captured of the moment really speaks for itself. Neon green swirls look truly otherworldly against a haze of bright purple blanketing Earth, which also seems enveloped in a ruby red glow. The reddish glow of the auroras can even be seen against the outside of the space station in this photograph.
Why is it incredible?
While her photograph speaks for itself, Adenot actually shared her own thoughts on the view via social media. One incredible thing about human spaceflight in the modern world is that, even from an orbiting laboratory, astronauts can share their experiences with the world in real time.
"Day 127, orbit 1968 — That aurora was absolutely spectacular… shimmering and dancing beneath us, stretching as far as the eye could see, and so intense it lit up the Station in shades of green," Adenot said. "We’ve seen several since the beginning of the mission, but this one was on a completely different level — far too bright for my usual aurora camera settings. Moments like these never get old up here; the whole crew suddenly find themselves vying for a good spot at a window!"
