Astounding footage shows an asteroid captured disintegrating as it entered Earth's atmosphere. Astronomers estimated it was one of the 40 to 100 tonnes of extraterrestrial matter that enters the planet every night. Dr. Michael Aye from the Berlin Institute for Planetary Research documented the event on Sunday, January 21.

Tiny Asteroid Detected Hours Before It Exploded Into a Harmless Asteroid
In the early hours of Sunday, a tiny asteroid streaked through the sky, colliding with Earth's atmosphere near Berlin. The impact resulted in a luminous, yet harmless, fireball that illuminated the surroundings for miles.
Such celestial events, although occurring a few times annually, gained distinction as this particular asteroid was unprecedentedly identified by scientists approximately three hours prior to its collision. This marked the eighth instance in which researchers detected a space rock before its impact.
The celestial body disintegrated upon entry around 1:30 am near the town of Nennhausen in Brandenburg. Discovered by astronomer Krisztián Sárneczky at Hungary's Konkoly Observatory, using the 60-cm Schmidt telescope, the asteroid, named 2024 BXI, prompted NASA to issue a detailed prediction of the meteor's striking location and time shortly after its discovery.
A live camera positioned in Leipzig, northern Germany, recorded the meteor's extraordinary brightness as it flashed into view and vanished within seconds.
Measuring around 3.3 feet (1 meter) in width before impact, the asteroid likely began disintegrating approximately 30 miles (50 kilometers) west of Berlin, potentially depositing meteorites along its trajectory, according to Denis Vida, a meteor physics postdoctoral associate at Western University.
Dr. Aye managed to capture the brief but vivid moment of the event on camera. The footage displayed a rapid descent of a bright white flame, indicating the ignition of the roughly one-meter-diameter asteroid.
The astronomer's fortuitous capture of this atmospheric phenomenon was made possible by a timely tip from his friend Franck Marchis, a renowned planetary astronomer at the SETI Institute, just as Aye was preparing to walk his dog.

The Quest for Early Detection Technologies
In recent years, Sárneczky detected asteroid 2022 EB5 around two hours before its impact on Earth's atmosphere, using data from the Konkoly Observatory. His exceptional ability to identify incoming space rocks is noteworthy since nearly 99% of near-Earth asteroids smaller than 98 feet (30 meters) remain undiscovered, as per the European Space Agency.
The challenges of detection increase with diminishing asteroid size, necessitating closer proximity to Earth for observation, making advance impact predictions more challenging. It is evident with certain near-Earth asteroids that can elude discovery by hiding in the sun's glare.
The 2013 Chelyabinsk meteor, emerging from the direction of the rising sun, serves as an example, causing widespread damage in Russia. To address such risks, government space agencies are actively developing advanced technologies for early asteroid detection.
Initiatives like NASA's NEO Surveyor satellite, scheduled for launch in 2027, and ESA's NEOMIR, expected after 2030, are part of these efforts. The Vera C. Rubin Observatory in Chile, funded by the National Science Foundation and operational from 2025, is poised to significantly enhance asteroid-hunting endeavors by cataloging the solar system from the ground.
Mario Jurić, the lead of the Rubin Observatory's solar system discovery team, notes that identifying 1.2 million asteroids took 200 years, but Rubin is set to double that count in its first three to six months, significantly advancing our understanding of the solar system's asteroid population.
