On January 27, 1880, Thomas Edison received a patent for an electric lamp using "a carbon filament or strip coiled and connected to platina contact wires." This wasn"t exactly the first light bulb, but it was the first practical and inexpensive one, a key technological innovation that introduced a new era. To mark the day, we"re looking at the bright lights of New York City and its surrounding area, as seen from the International Space Station.
