Stargazers in the Northern Hemisphere will be able to see one of the oldest known meteor showers starting next week if they can avoid bad weather and excessive artificial light.
Why it matters: The Lyrids meteor shower has been viewed by humans annually for around 2,700 years, with the first recorded sighting of them going back to 687 B.C. by the Chinese.
Heavy, relentless rains flooded Pittsburgh-area streets and prompted water rescues Thursday night, as a severe storm system threatened parts of the eastern U.S. into Friday.
The big picture: A rare flash flood emergency, the National Weather Service's highest flood alert category, was issued for parts of Pittsburgh, where up to 4 inches of rain had fallen just before 9:30pm Thursday.
