British Astronomer Patrick Moore Dies at 89

British astronomer and broadcaster Patrick Moore died Sunday, according to friends and colleagues. He died at his home in the coastal town of Selsey in southern England, according to a statement released Sunday. No specific cause of death was given, but he had heart problems and been confined to a wheelchair.

Moore was well known for his long-running BBC television show "The Sky at Night," which was credited for popularizing astronomy with generations of Britons. He had presented the show for more than half a century. It was signed by various staff members and friends, including Queen guitarist Brian May. May said Moore was irreplaceable and had stirred millions through his broadcasts.

"Patrick will be mourned by the many to whom he was a caring uncle, and by all who loved the delightful wit and clarity of his writings, or enjoyed his fearlessly eccentric persona in public life," May said.

He was known for his trademark monocle and his occasional xylophone performances and his frequently professed love of cats. He wrote dozens of books using a 1908 typewriter he received as a gift when he was 8. Moore had long expressed an interest in traveling into space, but said he wasn't medically fit to do so.
