CALIFORNIA — It was big, bright and mysterious – the perfect recipe for a social media frenzy.
A set of lights streaked across the sky in the southwest portion of the country late Wednesday night.
The fireball exploded into several pieces in the night sky over California, Nevada, Utah and Colorado.
Many people on social media hypothesized the lights were from a meteor or missile or even aliens.
But the National Weather Center in Salt Lake City splashed cold water on those theories.
It was just space junk re-entering the atmosphere.
Correction, the object in question was not a meteor but rather a piece of "space junk." https://t.co/iJkQtddAG6

Jonathan McDowell, an astronomer at the Harvard-Smithsonian Center for Astrophysics, said the space junk was a Chinese rocket burning through the sky.
Observation reports from Utah indicate the second stage from the first Chang Zheng 7 rocket, launched Jun 25, reentered at 0440 UTC
