NASA wants you ... to help find meteorites
The blazing meteor lit up the Alabama sky on May 18
This composite, wide-angle view of the meteor was captured from NASA's Marshall Space Flight Center on May 18. NASA has put out a call for any meteorites from the event.
The blazing meteor lit up the Alabama sky on May 18 and was spotted by all-sky cameras at NASA's Marshall Space Flight Center in Huntsville and the Walker County Science Center near Chickamauga, Ga.
Scientists estimate the space rock, which came from the asteroid belt, weighed about 60 pounds (27 kilograms), though it may have broken into pieces if any reached the ground.
"Expert opinion is that one or more pieces of this meteor survived to make it to the ground as meteorites, and calculations indicate that the area of the fall lies north of a line joining Woodville and Scottsboro," NASA officials said in a statement.
NASA is asking residents who saw the meteor, or those who may have noticed or picked up an unusual rock in the vicinity, to contact the Meteoroid Environment Office at the Marshall Space Flight Center.
