NEW DELHI:  NASA has just released new global maps of the Earth at night - the first since 2012. The stunning satellite images of Earth at night, referred to as "night lights," have been released every decade or so for nearly 25 years. Now, NASA scientists are trying to see if the night lights imagery can be updated more frequently - perhaps even daily. Doing so would drastically change how we forecast weather, improve natural disaster responses and even help track the effects of war.

Take a look at these two images of India showing how cities have grown and populations have spread in the past few years. The image below is from 2016. Compare it to the the second one from 2012.
