In brief
On Wednesday, a vibrant fireball streaked across the early morning sky near Mexico City, mesmerizing locals who recorded the event and shared it widely on social media. Known as a bolide, this astronomical spectacle captivated the public, leading to inquiries and discussions about these brilliant celestial occurrences.
According to reports from The Associated Press, a bolide is a type of fireball that explodes in a luminous flash, and may also exhibit visible fragmentation. The distinction is made by astronomer Jérôme Gattacceca, editor of The Meteoritical Bulletin, who explained that while a meteorite is a space rock that reaches Earth’s surface, a bolide is simply the bright phenomenon associated with its entry into the atmosphere.Dr. Gattacceca noted that meteors brighter than Venus are classified as "fireballs." While meteors and fireballs are common sights in the night sky, bolides are comparatively rare—though they do occur frequently, as highlighted by Guadalupe Cordero Tercero from the UNAM Institute of Geophysics. Cordero-Tercero estimates that an object measuring at least one meter in diameter enters Earth’s atmosphere approximately every two and a half days. Most of these entries go unnoticed as they fall into oceans or uninhabited regions.Denton Ebel, a curator at the American Museum of Natural History, expressed excitement about the event, stating that meteors are more common than many realize, particularly due to advancements in observational technology like fireball networks that capture these events on cameras. The recent incident also produced a sonic boom as the fireball traveled across the sky, suggesting that it fragmented at a relatively low altitude. Gattacceca explained that this type of noise indicates that meteorites likely reached the ground.Meteors originate from the asteroid belt, and when they enter the atmosphere, their high velocity enables even small rocks—sometimes as small as a walnut—to generate spectacular fireballs. The stunning display in Mexico City sparked widespread fascination among its more than 22 million residents, with experts assuring that there is no cause for alarm as no fatalities from falling meteorites have been recorded in history.Aimee Ortiz continues to cover breaking news and various topics from Mexico.
