• Residents of Chelyabinsk, Russia believe the green snow came from space
  • Chelyabinsk was once hit by the powerful mid-air explosion of a meteor
  • Local agencies were able to determine the nature of the green snow

Residents of a city in Russia that was once damaged by a violent mid-air explosion of a meteor are worried about the sudden appearance of green-colored snow. Many of them believe the green snow that blanketed parts of their city could be dangerous dust from space.

Earlier this week, the Russian media site Kurs Dela posted photos and videos of green-colored snow covering most of the city of Chelyabinsk. This prompted many residents in the area to believe that the odd-looking snow might be cosmic dust or a sign of an impending space threat coming their way.

Fears over the strange phenomenon stem from Chelyabinsk’s history involving threats from space. About seven years ago, the city was terrorized by a powerful explosion caused by a meteor.

According to reports, a meteor that was about 66 feet wide hit Earth in February 2013. Traveling at speeds of about 34,000 miles per hour, the meteor burnt up and exploded in the sky at an altitude of around 19 miles.

The explosion occurred over Chelyabinsk and released energy equivalent to over 30 atomic bombs. The powerful blast damaged over 7,000 buildings in the city. More than 1,000 people were injured due to the incident.

Due to this destructive incident, the city’s residents are worried that the recent appearance of green snow could be related to a looming cosmic disaster. In response to the speculations about the nature of the green snow, Russia’s Ministry of Ecology launched an investigation. Fortunately, the agency was able to provide a more Earth-based explanation regarding the origin of the strange substance.

According to the agency, the color covering the snow was most likely produced by natural dust that came from a nearby granite quarry. It stated that since the dust particles came from rocks and other natural materials, they are most likely not hazardous. The agency noted that it will still measure the air quality in the region to ensure public health safety.

Local authorities are also planning on investigating the quarry to learn more about the dust and why it was scattered all over the city.
