Hundreds of Facebook posts are urging parents around the world to take their children outside on Christmas Eve to scan the heavens for Santa Claus and his reindeer.
Assuming the skies are clear, there’s a good chance they will see a bright light crossing the skies. The light could be Santa — but it is actually the International Space Station, which has been orbiting the earth for 14 years.
The posts are pointing parents to Nasa’s “Spot the Station” web page where they can find the exact time the ISS passes over their town (17:22 in London and 18:35 in New York). The campaign has snowballed, with thousands sharing posts over the past few weeks to keep the story of Santa alive.
