In brief
On Wednesday, a vibrant fireball illuminated the darkened skies near Mexico City, mesmerizing onlookers as videos of the event quickly circulated on social media. This remarkable phenomenon, known as a bolide, was identified by the Associated Press. According to experts, bolides are intense fireballs that explode brilliantly upon entering Earth’s atmosphere and often display visible fragmentation.
Jérôme Gattacceca, editor of the Meteoritical Bulletin, explained that while meteors reaching the ground are termed meteorites, a bolide refers solely to the luminous spectacle occurring during atmospheric entry. As described by Dr. Gattacceca, fireballs are classified as meteors brighter than Venus, but bolides happen less frequently yet remain relatively common. Guadalupe Cordero Tercero, a researcher at the UNAM Institute of Geophysics and lead of the Mexican Meteor Network project, shared that a body at least one meter in diameter enters the Earth's atmosphere every two and a half days, although many go unnoticed as they fall in oceanic or unpopulated regions. Denton Ebel, a curator at the American Museum of Natural History, remarked on the excitement surrounding this event, noting that while meteors are more commonly reported due to fireball tracking networks, they occur more frequently than most believe.Reports indicated that the bolide produced a sonic boom as it dazzled observers, suggesting fragmentation at a low altitude, which may likely have resulted in meteorites reaching the ground. The sound has been described as reminiscent of a freight train, indicating substantial energy release. Dr. Gattacceca highlighted that all meteors originate from space rocks impacting the atmosphere at high velocities, with even small fragments generating a fireball effect. The event captivated the attention of Mexico City’s vast population of over 22 million, with experts assuring residents that such displays pose no danger, as no casualties have ever been recorded from falling meteorites in history.
