Astronaut Kimiya Yui recently unveiled an extraordinary timelapse video captured aboard the International Space Station (ISS). The footage highlights dazzling zodiacal light, vibrant auroras, and the Pleiades star cluster, all viewed from the vantage point of low-Earth orbit. This release commemorated Yui’s impressive milestone of spending 300 days in orbit.
The timelapse begins with an impressive showcase of zodiacal light, transitions into lively green auroras, and culminates with the appearance of the Pleiades cluster. Such visuals are unique from this orbital perspective, offering views unattainable from Earth’s surface.
Zodiacal Light: A Celestial Glow Above Earth
The video opens with a breathtaking sight of zodiacal light, a luminous band that becomes visible shortly after sunset or before sunrise. This phenomenon results from sunlight reflecting off tiny dust particles dispersed throughout our solar system, creating a subtle, radiant glow along the horizon. Viewed from the ISS, the light extends elegantly over Earth’s curved silhouette, presenting a rare and splendid spectacle.
Zodiacal light is typically observed in remote, dry environments with minimal light pollution, yet in space, it appears with remarkable clarity. As detailed by Space.com, Kimiya Yui’s video brings this natural marvel into crystal-clear focus for viewers worldwide.
“As a token of gratitude for allowing me to have such a precious experience over 300 days, I’d like to introduce a slightly unusual timelapse from the window,” Yui posted on X, sharing the video along with the message.
Earth’s Auroras Light Up the Night
Once the zodiacal glow dims, the focus shifts to the vibrant auroras shimmering in Earth’s upper atmosphere. According to NOAA, these colorful lights occur when solar wind particles collide with the planet’s magnetic field, energizing atmospheric gases and creating dazzling displays near polar regions.
Yui’s sequence reveals the auroras swirling above northern latitudes, glowing brilliantly against the dark expanse of space. The video also demonstrates the ISS’s solar panels rotating to maintain optimal sun exposure.
The Pleiades Seen from Space
Near the conclusion of the timelapse, the Pleiades star cluster—often called the “Seven Sisters”—comes into view. Located within the constellation Taurus, this cluster of bright stars is easily visible to the naked eye on Earth. Yui’s footage offers a striking vantage point as the cluster moves across the ISS’s orbit.
Scientists have extensively researched the Pleiades to better understand star formation and lifecycle processes. This remarkable video was recorded from a space station circling approximately 400 kilometers (250 miles) above our planet.
