A family in Houston is counting their lucky stars that no one was hurt after a cantaloupe-size meteorite smashed through the roof of their home and ricocheted around an empty bedroom. The space rock is most likely a fragment of a meteor that witnesses saw breaking apart with a bang in the bright-blue Texas sky.

The exploding space rock is one of several other “fireballs” that have been spotted streaking across the U.S. over the past few days. These unusually frequent light shows are the result of a peculiar trend that scientists still don’t fully understand.
