Ring of Fire in the Sky! A Spacecraft Just Filmed the Northern Lights From Above the North Pole
Quick Summary
A spacecraft called SMILE has captured something almost no human has ever seen: the full ring of northern lights glowing around Earth’s North Pole, all at once, from high above in space. Today, NASA chose this video as its Astronomy Picture of the Day. It is the first time a spacecraft has filmed the complete aurora ring in ultraviolet light since 2008.
What Happened?
You have probably seen photos of the northern lights — those colorful ribbons of green, purple, and pink that dance across the sky on dark nights near the Arctic. They are beautiful. But here is something surprising: from the ground, you can only ever see a tiny piece of them. The full display actually forms a huge glowing ring around Earth’s North Pole, like a giant halo. It is so large that no person standing on the ground could ever take it all in.
But a spacecraft can.
SMILE stands for Solar wind Magnetosphere Ionosphere Link Explorer. It is a joint mission built by scientists from Europe and China. After launching on May 19, 2026, SMILE climbed into a special oval-shaped orbit that swings very high above Earth’s North Pole — about 121,000 kilometers up. That is about 10 times farther from Earth than the International Space Station. From that height, SMILE can watch the entire aurora ring at once, the way you might look down at a hula hoop laid flat on the floor.
SMILE’s special camera, called an Ultraviolet Imager, recorded the full auroral ring on July 24. The camera sees ultraviolet light — a kind of light our eyes cannot detect. That matters because ultraviolet light cuts right through sunlight’s glare, letting SMILE spot auroras even on the dayside of Earth, where it is bright and sunny. No previous spacecraft had pulled off that trick since NASA’s Polar mission ended in 2008.
The footage shows the ring of light brightening and rippling as a burst of energy from the Sun — called an auroral substorm — raced through Earth’s magnetic field. The camera can record for up to 45 hours in a single orbit, like a very patient watchman.
Why Does It Matter?
The northern lights are not just pretty. They are a sign that the Sun’s invisible wind of charged particles is crashing into Earth’s magnetic shield. Sometimes these crashes are strong enough to knock out satellites, disrupt GPS, and even damage power grids.
By watching the whole aurora ring at once, scientists can track storms in Earth’s magnetic field like a weather forecaster tracks a hurricane. SMILE will help researchers predict dangerous space weather before it causes trouble — protecting astronauts, satellites, and the electrical systems people depend on every day.
Big Words
- Aurora — a glowing light display caused when particles from the Sun crash into Earth’s upper atmosphere
- Ultraviolet light — a type of light that is invisible to human eyes but can be detected by special cameras
- Magnetosphere — the invisible magnetic bubble that surrounds Earth and protects it from the Sun’s wind
- Substorm — a sudden burst of activity in Earth’s magnetic field that causes the aurora to flare brighter
- Solar wind — a constant stream of tiny particles flowing outward from the Sun in all directions
Fun Fact
The full auroral oval around the North Pole can be thousands of kilometers wide — about the same distance as driving across the entire United States from New York to Los Angeles!
Think About It
If you could travel 121,000 kilometers above Earth to watch the auroras from space, what do you think the view of our whole planet would look like?
