A mysterious fireball fell to earth in Texas over the weekend - prompting speculation that it was related to the orbital collision of two stallites last week.

The US Federal Aviation Administration said it had received numerous reports of a fireball and falling debris across Texas on Sunday.
A television station in Austin, Texas was filming a marathon at the time, and caught the pictures of the debris falling from the sky.
A spokesman for the Williamson County Sheriff's Office in Georgetown said that deputies and firefighters were out looking for debris after callers said they thought they saw a plane crashing.
The department took its helicopter up to search for the source of the debris, but found nothing, the spokesman said.
Golfers at Avery Ranch Golf Club in Austin, Texas say they looked up and saw something zooming through the sky with flames trailing behind.
One golfer, Jim Havener, said the debris looked like a 'bright ball that had an elongated gold-ish tail on it.'
Another golfer, Jerry Swartz said he was expecting to see some kind of explosion.
The FAA had notified pilots on Saturday to be aware of possible space debris after the collision on Tuesday between US and Russian communication satellites.
However, the US Strategic Command insisted there was no connection to the sightings over Texas and Tuesday's collision of satellites from the US and Russia.
The chief of Russia's Mission Control says clouds of debris from the collision will circle Earth for thousands of years and threaten numerous satellites.
