Residents in parts of Spain and Portugal were treated to a spectacular light show when a fragment of a comet blazed across the sky, creating a brilliant blue fireball. An observer described the event as “feeling like a movie.”
The footage of the celestial event, shared by the European Space Agency (ESA) on social media platform X on Sunday, was said to be taken by the ESA’s own “fireball camera.”
Initially believed to be a “stunning meteor,” the ESA later clarified that the blue streak seen above the city of Caceres in Spain was the result of a “small piece of a comet” and not an actual meteor. The fragment disintegrated over the Atlantic Ocean, traveling at an estimated speed of 28 miles per second.
According to the ESA, there is a very low chance of recovering any meteorites following the event.
Several videos from different cities in Spain and Portugal circulated on social media platforms, capturing the high-speed comet fragment as it illuminated the skies in shades of blue and green.
This is congruent with NASA’s explanation that meteors containing magnesium often burn with a blue-green glow.
Scientists from the Spanish Calar Alto astronomical observatory revealed that preliminary analyses conducted by the Andalusia’s Institute of Astrophysics indicated the object had a “cometary origin”. CCTV footage provided by Cadiz’s mayor’s office captured the fireball passing overhead at 12.46am local time (11:46pm UK time).

In another striking moment, a performer at a concert in the Portuguese city of Barcelos was overshadowed by the fireball as it tore across the sky. Residents in Porto, Portugal’s second-largest city, also witnessed the nocturnal skies burst into light for a few seconds.
Following the event, there were numerous calls made to emergency services.
One Lisbon local, Bernardo Taborda, described the intense green light that lit up the night: “It was as bright as daylight… we all saw it.” Taborda, along with his friends, was awestruck by the unexpected event, commenting further, “It was like something out of a movie, we were all stunned… it was incredible.”
