Early risers in North America and Europe might spot something special on Christmas morning—a bright, silent light gliding across the sky just before sunrise. This won’t be a blinking airplane or a shooting star. Instead, it will appear suddenly, move steadily, and fade away within minutes. For kids wide awake with excitement, it could seem like a magical journey happening in the dawn sky.
What’s happening? This Christmas, the International Space Station (ISS) will reflect sunlight and shine like a star during early morning passes, making it one of the brightest objects overhead. This fleeting sight can be both a seasonal wonder and a modern marvel.
But why is the ISS visible? The ISS orbits Earth about every 90 minutes, reflecting sunlight as it glides through the atmosphere. This makes it a spectacular sight with no special equipment needed—just your eyes and a clear sky.
Here are some key times to catch this Christmas surprise in a few major cities:
- New York: Dec. 24, 6:43-6:48 a.m. EST (~5 min)
- Chicago: Dec. 24, 5:42-5:45 a.m. CST (~3 min)
- London: Dec. 24, 7:04-7:10 a.m. GMT (~6 min)
- Rome: Dec. 25, 7:19-7:22 a.m. CET (~3 min)
Spotting the ISS is simple. Just find a place with a good view of the sky. You might not have to wait long; even just a few minutes can lead to a beautiful spectacle. The excitement of seeing the ISS can spark curiosity about space and science, especially among young viewers.
Many people share their ISS sightings on social media. Posts often include photos and videos, expressing awe at the sight. You might find hashtags like #SpotTheStation or #ISS Christmas lighting up feeds during the holidays, showing just how captivating astronomy can be. In fact, a recent survey showed that nearly 60% of families in the U.S. express interest in stargazing and other astronomy-related activities during the holiday season.
If you’re curious about future sightings, NASA’s Spot the Station provides updates on when the ISS will be visible from your location.
