Eastern China including the capital Beijing is facing extreme air pollution these days. You can imagine the extent through the fact that the smog is visible from space.
Here is a photo revealed by NOAA. This picture was taken by Suomi NPP Satellite which is 824 km above the Earth’s surface and is jointly managed by NASA, NOAA and DoD.
As per USEPA standards, the air quality was measured 755. An air quality measuring 500 is considered very bad. Anything exceeding 500 is extremely toxic and hazardous.
The smog is so dense that anything is barely visible even at a very short range. Look at another photograph. It’s not an alien colony in some extraterrestrial planet. It is a photograph taken at Beijing.
