Late last night, the National Astronomical Observatory-Rozhen detected a glowing object the size of a car or a bus. The observatory’s director Nikola Petrov told BNT that it was not a meteorite or asteroid, but debris from artificial satellites orbiting the Earth. According to him, these non-functioning objects are called "space junk", with over 200,000 such pieces currently in space. 

Similar phenomena in the sky are likely to become more frequent in the near future. While this debris is still safe for now, in 20-30 years it could potentially pose a threat to the Earth's inhabitants, said Nikola Petrov.
