The ban on incandescent lightbulbs has officially gone into effect in the U.S., more than a decade after the federal government first passed a rule prohibiting the non-energy efficient lighting. The issue was first addressed in 2007 with the enactment of the Energy Independence and Security Act, which set maximum power requirements for all general service lightbulbs.

It was simply excess fuel that had been released from a SpaceX rocket that launched from California about three hours before the spiral appeared. Sometimes rockets have fuel that needs to be jettisoned, said space physicist Don Hampton, a research associate professor at the University of Alaska Fairbanks Geophysical Institute. “When they do that at high altitudes, that fuel turns into ice,” he said. “And if it happens to be in...
