A new set of updated maps showing Earth's urban night lights can be accessed on NASA's new Worldview website:

However, note this: "Worldview uses a set of browser technologies that are not currently supported by Internet Explorer. We are awaiting the release of IE version 10 and are hopeful that it will load Worldview properly. In the meantime, please try loading this page in Mozilla Firefox, Google Chrome, Apple Safari, or a tablet device."
Can zoom to Malaysia / Singapore and see the newly updated maps. However, it seems that the resolution is not as high as that on Google Earth's current night city lights feature/layer.

And here are some news items:
"Scientists unveiled today an unprecedented new look at our planet at night. A global composite image, constructed using cloud-free night images from a new NASA and National Oceanic and Atmospheric Administration (NOAA) satellite, shows the glow of natural and human-built phenomena across the planet in greater detail than ever before."

"The scientists were surprised by some of the things they discovered using VIIRS, like something called "night glow," which is the glow of the upper atmosphere that can illuminate clouds and ice well enough to see detailed visible light features at night even better than in infrared."

"The importance of a telescope is not how big it is, how well made it is.
It is how many people, less fortunate than you, got to look through it."
