Mysterious Green fireball seen streaking across Moscow skies at Dawn: Heavenly body or something more?

The sky is home to numerous mysterious celestial objects that even science is unaware of, and more often than not, when one such heavenly object streaks across the sky, it sparks both fascination and fear among the masses.


Recently, the night sky over Moscow was set ablaze by a spectacular green fireball, captivating early morning commuters and residents across the Russian capital. This mysterious celestial light show, captured in numerous videos and shared widely online, has stirred not only amazement but also thoughtful discussions around space objects, their identity.

A mysterious green glow ball was spotted streaking across the Moscow sky

On October 27, 2025, at dawn, people across Moscow and nearby areas witnessed a bright, vividly green fireball streaking across the sky. This glowing object was visible for several seconds, trailing sparks and leaving a spectacle behind. The green colour and fragmentation patterns looked similar to a "fireball," as the scientists call it, which is a particularly bright meteor burning up in Earth's atmosphere.

According to a Gulf News report, Geologist Sergio Almazan compared this sighting to the 2013 Chelyabinsk meteor, also seen in Russia, which caused injuries and reminded the world of the potential dangers these space rocks can pose. Fortunately, no damage or injuries were reported from the Moscow fireball this time, making it just a beautiful visual event rather than a destructive one.

What is the 2013 Chelyabinsk meteor incident

According to a report by the National Museum of Scotland, the 2013 Chelyabinsk meteor was a massive asteroid about 20 meters wide that entered Earth's atmosphere over Chelyabinsk, Russia, on February 15, 2013. Traveling at nearly 69,000 kilometers per hour, it exploded in the air about 30 kilometers above the ground, releasing energy equivalent to 400-500 kilotons of TNT, which is roughly 30 times the power of the atomic bomb dropped on Hiroshima.

The bright flash was visible over a wide area, and the blast wave shattered thousands of windows, injuring around 1,500 people.

What gives colour to fireballs burning in the sky

The green hue is typically caused by the presence of nickel in the meteor's composition. Magnesium and nickel are common materials in both natural meteoroids and space debris, such as defunct satellites. A netizen explained on social media, “Magnesium and/or nickel burning up during reentry gives this hue. So it's a meteorite made mostly of that, or a satellite of some kind as those materials are commonly used for making them.” Another added, “If it's truly burning green, that means a 1970s or before satellite from lots of copper wiring.”

A scientist says it was a meteor

Sergi Bogatchev, a scientist at Russia's Space Research Institute, told Russian media that the object was most likely a small meteor burning up in the atmosphere. The trajectory and disintegration of the fireball resembled typical meteoric behaviour, caused by friction as the object entered the Earth's atmosphere at high speed.

Social media response

Social media responses ranged from awe to humorous speculation, with one user jokingly saying, “Thor landed in Russia,” and others attributing the spectacular sight to secret weapons or unidentified aerial phenomena. Regardless of the theories, experts emphasize that such fireballs are natural occurrences, with the green glow resulting from the burning of specific metals.


This sighting also renewed interest in objects like Comet 3I/ATLAS, which has attracted attention for its unusual characteristics, leading astrophysicists like Avi Loeb and Michio Kaku to speculate about its nature.
