What is believed to be a meteor lit the sky over eastern Cuba and caused an explosion, scientists on the island said Saturday. There were no reports of damage or injury.

The head of the National Seismological Service, Enrique Arango Arias, told the official Cubadebate news site that the phenomenon was noticed in the towns of Moa, Sagua de Tanamo and Maisí .

He said the service's instruments "registered the expansive wave" of the explosion.

Social media users reported seeing red and white light followed by an explosion at about 10:06 p.m. local time Friday.

President Joe Biden has chosen a former senator from Florida who flew on the space shuttle just days before the Challenger launch accident to lead NASA.

Biden on Friday announced his intent to nominate Bill Nelson as the space agency's administrator.

Nelson, 78, grew up near Cape Canaveral and was serving as a Democratic congressman when he launched aboard space shuttle Columbia in January 1986. His commander was Charles Bolden Jr., who later served as NASA administrator under President Barack Obama—at Nelson's urging.

Nelson was elected in 2000 to the Senate, where he served until his defeat in 2018.

If confirmed by the Senate, Nelson will become NASA's 14th administrator, succeeding another former member of Congress, Jim Bridenstine, a Republican from Oklahoma.

This is a critical time for NASA as momentum accelerates in the commercial space program.

SpaceX is about to launch its third flight of astronauts to the International Space Station for NASA; Boeing is expected join the crew delivery effort later this year. Space station supply runs, meanwhile, have been handled by private companies under contract to NASA for nearly a decade.
