As the coronavirus sweeps through the world, shutting thousands of factories and locking down millions, the impact is visible from space. A satellite that detects traces of human activity — tailpipe emissions, fossil fuel burned in power plants and other industrial activities — shows striking reductions in pollution over China and Italy.

Both countries have taken unprecedented measures to limit the movement of people in order to slow down or contain the spread of the disease.

On January 25, the global death toll was 41, all of them in China. By February 14, 1,383 people had been killed, all but two of them in China. An average 65 new deaths occurred daily in China from January 25 to February 14, peaking at 254 deaths of February 13 before falling to just 13 on February 14. China got some grip on the number of daily deaths thereafter.

“It’s the first time in history we’ve seen something live this,” said Marco Percoco, a transportation exonomist at Bocconi University in Milan, referring to the speed and size of the pollution declines.
