Earth glows like a half moon while a giant aurora writhes over the North Pole in this ultraviolet image from the new Smile spacecraft.<\/p>\n

Quick facts<\/p>\n

What it is: An aurora on the sunlit side of Earth<\/p>\n

Where it is: Over the North Pole, as seen from about 75,000 miles away<\/p>\n

When it was shared: Sept. 30<\/p>\n

The debut images from a new Earth-observing satellite have just given us a view of the impossible: giant auroras<\/a> rippling over the North Pole in broad daylight.<\/p>\n

Earth’s auroras are one of our planet’s signature wonders \u2014 a sight worth advertising in interstellar travel guides, alongside our perfect total solar eclipses, bright shooting stars and majestic blobfish<\/a>. They are the beautiful result of electrical storms in the atmosphere, appearing when charged solar particles skate along Earth’s magnetic-field lines and collide with light-emitting molecules near the poles. (Auroras do exist on other planets<\/a>, but they are usually not in bright visible colors like ours.)<\/p>\n

<\/p>\n

To human eyes, auroras come out only at night and rarely stray from the poles. That’s what makes these first observations from the joint European-Chinese Smile mission<\/a>, which officially began science operations this week, so special.<\/p>\n

Captured in ultraviolet light, the stunning images show a huge, serpent-like ring of charged particles coiling around the North Pole in July 2026. In the foreground, Earth appears ghostly and featureless, glowing like a half moon. The aurora writhes around our planet’s sunlit side, covering about a third of it, while Earth’s dark nightside bleeds into the background sky. Far behind, bright stars fall like raindrops as Smile shifts subtly in its orbit.<\/p>\n

Smile tested its soft X-ray imager on the light of the distant supernova remnant Cassiopeia A (center), located 11,000 light-years from Earth.<\/p>\n

The view alone is worth smiling about, but the new images also promise exciting science to come. Taken just two weeks after scientists first turned Smile’s Ultraviolet Aurora Imager on, the observations show that the satellite’s instruments are working as they should and that the joint European Space Agency (ESA) and Chinese Academy of Sciences mission can officially begin.<\/p>\n

Launched on May 19, Smile will spend the next three years watching Earth from a highly elliptical orbit that takes it about 75,000 miles (121,000 kilometers) over the North Pole \u2014 about a third of the way to the moon. From there, Smile can observe the North Pole for a record-breaking 45 hours at a time, offering an unprecedented view of solar activity there.<\/p>\n

In addition to the Ultraviolet Aurora Imager, Smile carries three more science instruments to detect X-rays, magnetic fields and light ions over Earth.<\/p>\n

This week, scientists also tested the spacecraft’s soft X-ray imager by pointing it at the distant supernova remnant Cassiopeia A, located about 11,000 light-years from Earth (image above). Although the camera is working fine, the detector is still picking up a bit too much light when aimed at Earth, so it will require a bit more calibration from scientists on the ground.<\/p>\n
