On February 28, 1986, the small town of Dalinergorsk in the Russian Far East witnessed an incredible sky phenomenon. At 7:55 PM, a red sphere traversed the sky from the southwest, ultimately crashing in the suburbs at 611 Heights. Witnesses described the sphere as being about 2 to 3 meters in diameter, silent, and leaving no trace behind. Upon impact, the sphere struck a cliff, causing the rocks to heat up and glow, resembling the arc light produced by a short circuit or welding.
The crash site was littered with lead alloy pellets, weighing a total of approximately 70 grams and ranging from 0.5 to 6 millimeters in diameter. Some of these lead pellets were irregular hexagons with sharp surfaces, the heaviest weighing about 2 grams. Laboratory tests revealed that these pellets contained various elements, including rare earth elements such as lanthanum, zirconium, praseodymium, cesium, molybdenum, tungsten, and yttrium. Additionally, around 30 grams of small iron beads were found, along with a black, brittle, net-like substance.
The origin of these materials remains a mystery, sparking widespread speculation within the scientific community. Some believe it could be a rare natural phenomenon known as ball lightning, while others speculate it might be debris from a satellite or rocket. Some scholars even suggest it could be part of a malfunctioning device from extraterrestrial intelligent beings.
This incident attracted the attention of the Russian Academy of Sciences, which dispatched an investigation team to conduct detailed research in an attempt to uncover the secrets behind the red sphere.
